1 GENERAL 1.1 This Procurement Specification covers non–electrolytic anticorrosive coatings derived from water or solvent dispersions of zinc and aluminum flakes and following stoving, for ferrous material parts. Stoving temperatures can vary from about 180°C for solvent–based organic systems, to about 300°C for water–based inorganic systems. Topcoat finishing additional treatments can be applied on the base coating to improve the corrosion and abrasion resistance, to give a particular color and/or to modify the friction coefficient by adding, in this case, special additives such as wax or PTFE. 1.2

Purpose Main purpose of the coating dealt with in this Procurement Specification is to give to treated parts a high resistance to corrosion and to ensure a controlled value of the friction coefficient.

Coatings covered in this Procurement Specification shall comply with prescriptions in Annex CK of P.S. 9.01102 and shall be completely free from chromium compounds. 1.3

Field of application Depending on the type of parts to be treated, non–electrolytic coatings with zinc and aluminum flake base can be applied following one of these procedures: – bulk dip / spin; – rack dip / spin;

As a general rule, bulk processes are suitable for small or medium–size parts, while rack processes are suitable for medium–size or large parts. For parts with indents – blind holes, socket screw heads, nuts – and/or fine threads, it is necessary to use systems and working cycles able to avoid product deposits in these areas or to guarantee their removal. These coatings must not be utilized in the following cases: – Self–locking nuts with polyamide core. – Parts for which a good electrical conductivity is required (e.g. ground connections). – Only as concerns the coatings obtained by water dispersions, for components made of materials for which the temperatures of 300°C cause a decay of the mechanical characteristics. Furthermore they are not recommended for: – Internal and external threads < M6. – Parts for which welding operations are foreseen after the application of coating. For parts to be used on exposed areas (e.g.: under floor, engine compartment, vehicle exterior), assembled with stainless steels, magnesium alloys copper alloys, rubber or other elements subject to create contact corrosion with zinc, it is necessary to use coatings with appropriate additional finishings, to specify on drawings.

PIn these cases, it is always advisable to check the suitability of the solution chosen by means of targeted corrosion tests, to be agreed upon between Customer and Supplier. 1.4

Flexibility and resistance to shocks The coating must resist normal extensions and compressions required to springs, as well as normal bending stresses to which elastic washers and flat springs are subject during the assembly, without showing scaling or loss of adhesion from the base metal. Moreover, it must resist the normal handling and storage conditions without showing scaling, detachment from the base metal or other important damages. 1.5 Look Unless otherwise specified on drawings, the coating shall present a uniform semi–opaque silver grey color (Silver). A different color can be required (e.g. black), it is usually obtained by applying one or more additional finishing coats which can affect the thickness of the coating (indicatively greater than 15 mm total), making it potentially critical for fine metric screw threads. 1.6 Classification, designation, indication on drawing and use

If the Designers think it is necessary to bind the use of a specific product/process, it is possible to indicate on the drawing the commercial name of the products used and of their Manufacturers (see Annex 2 and § 2.5.3)  The application of the lubricants can be carried out also on Type II coatings. In this case, the drawing prescription of the coating shall be: RIV/EC 5 F LUB P.S. 9.57513 and shall complulsorily be followed by the indication of the dispersion limits of the Cf required.  All colors different from silver grey shall be explicitly indicated on drawing, e.g.: RIV/EC 8 PL Black P.S. 9.57513, or RIV/EC 5 LUB Green P.S. 9.57513 (see Annex 2).  Cf dispersion limits different from 0.10 to 0.16 shall be specified on drawings (see § 2.5). 1.7

Dimensions and tolerances of the coated part 1.7.1

1.7.1.1 If not otherwise indicated, dimensions and tolerances indicated on the part drawing are considered as including the coating. 1.7.2

Coating thickness on bolts 1.7.2.1 When applied on threaded elements, the coating must not affect the normal assembly and dismounting operations. The measure of the coating thickness is defined as per the tolerance of the ISO metric thread, according to Standard UNI 5541, with tolerance classes: – g , f and e for outer threads (screws); – H and G for inner threads (nuts). In case of outer threads, these tolerances are considered before applying the coating while, in case of inner threads, they are considered after coating. After coating, the higher deviation must not exceed zero (nominal dimension) in case of outer threads and be lower than zero in case of inner threads. a) Screws

The thickness values of coatings for screws are defined in function of thread pitch and tolerance field of thread. Table 1 shows the maximum theoretical thickness values that can be required; they are obtained from the values of the main deviations from tolerance positions g, f and e.

Even thickness values higher or lower than the indicated ones can be required. Thicknesses higher than the indicated ones must be agreed upon by Purchaser and Supplier, for, in addition to the main deviation, a part of the thread tolerance could be utilized and a decrease of some micrometers could occur on the average diameter in position “h/H”; nevertheless, in any case the screw – nut coupling must not be compromised. b) Nuts

Differently from the electrolytic coatings, the coatings dealt with in this Procurement Specification tend to accumulate in inner threads too. Therefore the female threads must be suitably increased in order to ensure the meeting of tolerance 6H after applying the coating.

2 REQUIREMENTS FOR THE COATING QUALIFICATION 2.1 Submit the component to tests and checks indicated in the following paragraphs, checking the compliance of the test result with the values/limits indicated in the design and/or in the annexed “Specifications Data Sheet”, concerning the specific type. 2.2 Test environment (unless otherwise specified) Temperature : 23 ± 5 °C Atmospheric pressure : 860 to 1060 mbar Relative humidity : 45 to 70 % PUBLISHED BY SATIZ - NORMAZIONE

Coating materials and processes The material and coating processes that are approved by FIAT AUTO are listed in Annex 2 . 2.4

Characteristics The characteristics indicated below refer to the significant surface of the part. The term significant surface means the surface part that is essential for the look and/or utilization of the treated component. It can be indicated on drawing or agreed upon when ordering; otherwise the whole part surface is considered to be significant. In case of bolts, the significant surface includes head and stem of screws, operation slots, possible inseparable washers and the outer surface of nuts. 2.4.1 Visual inspection The part surface must be free of defects such as porosity, inclusions, cracks, blisters, drops, etc. and of zones without coating. The coating must have a look conforming with what required in § 1.5, it must be catalyzed perfectly, with a not greasy or sticky hand (for versions LUB too); it must resist normal handling, storage and installation operations without flaking, scaling or, in any case, losing adhesion. No accumulation of product that can affect the tightening operations must occur on bolts, on threads and in operation slots. 2.4.2 Check the absence of hexavalent chromium compounds in the coating composition As per Standard 7.M5000. 2.4.3

2.4.3.1 Coating thickness for components other than bolts and nuts The minimum local thickness, measured in significant surface zones by one of the methods indicated below, must result as indicated in § 2.4.3.6, for the various types of coating. 2.4.3.2 Magnetic method As per Standard ASTM B 568 or FIAT Standard 50757, making use of Magne–Gage, Mikrotest or other equivalent equipment that permits an accuracy of at least ± 10 %. To be utilized in current checks. 2.4.3.3 X–ray fluorescence method As per Standard ASTM B 568. Of general use, to be utilized preferably in case of small–size parts. It requires a specific calibration for every type of coating. 2.4.3.4 Micrographic method As per Standard ASTM B 487 or FIAT Standard 50758.

2.4.3.5 Bolt coating thickness The coating thickness on threaded elements must not compromise the normal tightening and dismounting operations. In the meantime, it must meet the requirements indicated in §§ 2.4.5 to 2.4.7. Unless otherwise arranged, after coating, metric threaded parts shall be manually screwable on the test gauges, ring type or thread plug type, with tolerance position “h” for external threads and “H” for internal threads. In this case the screwing operation, for the first 3 threads shall be done by exerting a max. torque complying with values in P.S 9.52605/01 both for screws and for nuts. 2.4.3.5.1 Zones for the measurement of the bolt coating thickness As a consequence of the variability of the coating thickness on screws and nuts, it is measured in points significant from the point of view of anticorrosive protection. In case of hexagonal or outward--torsion, these points lies approximately at the center of the head surface or of the stem end. In case of cylindrical screws with countersunk hexagonal head and of screws with cross cut, the measuring points lies on the flat surface of the head, between edge and countersunk hexagon, between edge and cross cut, or on the side of the head. Countersunk and cut surfaces are excluded from the measuring points. In case of nuts, thickness is measured on a side of the hexagon or on a support plane. 2.4.3.5.2
