SCOPE These specifications define the minimum heat and corrosion performance requirements for chassis and engine components. 2. APPLICA
5、TION WSS-M2P170-B1: To be used on non-visible engine brackets, brake components, and exhaust hangers where operating temperatures do not exceed 250 C. WSS-M2P170-B2: To be used on moderately visible engine brackets, drums, rotors, and calipers where operating temperatures do not exceed 250 C. WSS-M2
6、P170-B3: To be used on non-visible cold-end exhaust components, such as exhaust hangers, where corrosion protection is desired and where operating temperatures do not exceed 450 C. WSS-M2P170-B4: To be used on moderately visible cold-end exhaust components, such as muffler rear heads and tail pipes,
7、 where operating temperatures do not exceed 450 C. WSS-M2P170-B5: To be used on non-visible hot-end exhaust components, such as catalyst hardware, where exceptional heat and corrosion protection properties are required. Temperature resistance is 650 C maximum. WSS-M2P170-B6: To be used on moderately
8、 visible hot-end exhaust components, such as exhaust manifold components, where exceptional heat and corrosion protection properties are required. Temperature resistance is 650 C maximum.

REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part
10、producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.2 SUBSTRATE PROPERTIES 3.2.1 Substrate As specified on the Engineering Drawing. Except for Chip Resistance, all requirements of these specifications must be validated with actual production inte
11、nt components. 3.2.2 Metal Preparation All surfaces to be coated must be free from oil, grease, rust and other foreign materials. Phosphating or other surface preparations must comply with the coating manufacturers recommendations. 3.3 FILM PROPERITES 3.3.1 Color As specified on Engineering Drawing
12、3.3.2 Initial Hardness The finish shall be sufficiently cured at the time of packing to withstand normal handling and shipping without damage. 3.3.3 Adhesion (ASTM D3359) Method A, X-cut Tape Test 4A or better Method B, Cross-Cut Tape Test 4B or better Available surface area and contour of the compo
13、nent determines which method to use. If both methods are suitable, then Method B is preferred. When using Method A, a minimum of three X-cuts per part is required to increase sampling area. Adhesion tests to be performed 24 hours after curing, per manufacturers recommendation. For air dry coatings,
14、age samples for 72 hours prior to the adhesion test. 3.3.4 Film Thickness (FLTM BI 117-01, ASTM B487) Coating thickness must be sufficient to meet all the performance requirements of these specifications. Minimum coating thickness must be listed on the print and should be based on production intent
15、parts. Example: Company X High Temp Paint 123 per WSS-M2P170-B1, 20 m min ENGINEERING MATERIAL SPECIFICATION WSS-M2P170-B1/B2/B3/B4/B5/B6/B7 Copyright 2013, Ford Global Technologies, LLC Page 3 of 6 3.4 RESISTANCE PROPERTIES 3.4.1 Chip Resistance, max 5B (SAE J400, Method C, Method II) Test shall be
16、 conducted on production intent components or on panels. The test panel must have the same substrate (i.e. cold rolled/hot rolled steel, cast iron, wrought/cast aluminum) and be painted on the same system as the production intent component. Or (FLTM BI 157-06) 6 3.4.2 Laboratory Accelerated Cyclic C
17、orrosion Test (CETP 00.00-L-467, ASTM D610) Prior to corrosion testing, samples must be preconditioned per the heat resistance test (sec. 3.4.6). For air dry coatings, samples must be aged at ambient conditions for 72 hours prior to testing. Air dry coatings shall be tested with and without heat age
18、 preconditioning. WSS-M2P170-B1/B3/B5 4 weeks WSS-M2P170-B2/B4/B6 6 weeks WSS-M2P170-B7 9 weeks The part must be rated no worse than Grade 6 as defined by ASTM D610. Parts with sharp edges, recessed areas, rough surfaces, or welds may have reduced corrosion resistance at these locations. For exhaust
19、 components, a 315C heat soak with ice water bath quench once per week shall be performed. At test termination, highly visible components must have an acceptable as-installed appearance after cleaning and/or polishing based on a jury evaluation of at least two people, one person from Ford Product En
20、gineering, and the other from either Ford Product or Materials Engineering. Final judgment of corrosion performance should be based on visibility of the parts as observed from the rear, engine compartment, or in the wheel wells of the vehicle as described by in Total Vehicle Corrosion Resistance Tru
