SCOPE These specificatio

5、ns define the performance of an electrolytic or non-electrolytic plating of zinc, followed by a trivalent chromium conversion, followed by the application of a topcoat sealer. 2. APPLICATION These specifications were originally released for coatings where resistance to corrosion is required for fast

6、eners and fuel injector components. These coatings are effective for preventing galvanic corrosion of steel fasteners that contact magnesium or aluminum components. Caution: These coatings are not recommended for severe abrasion conditions or where chip resistance is required. 2.1 SERVICE APPLICATIO

7、N 2.1.1 The maximum service temperature resistance of these coatings is 120 C. 2.1.2 Electrical Conductivity 3. REQUIREMENTS Material specification requirements are to be used for initial qualification of materials. 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS ENGINEERING MATERIAL SPECIFICATIO

8、N WSS-M21P17-B1/B5 Copyright 2013, Ford Global Technologies, LLC Page 2 of 3 Material suppliers and part producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.2 APPEARANCE 3.2.1 The plating shall be smooth, fine grained, adherent, and free from bli

9、sters, pits, nodules, indications of burning, and other defects. All details of workmanship shall conform to the best practice for high quality plating. 3.2.2 Parts shall have a silver-white color. 3.3 PERFORMANCE CHARACTERISTICS Items to be tested for adhesion, plating thickness, or corrosion testi

10、ng shall be air cured for 24 h prior to testing. 3.3.1 Adhesion Mechanically Plated Parts Only (B2 & B4) Parts heated to 100 C for 30 minutes shall exhibit no blistering, peeling, or flaking of plating that can be removed by a filament type tape. The testing of plate quality by salt spray and/or det

11、ermination of coating thickness shall be done on parts passing the adhesion test. 3.3.2 Plating Thickness, min 8 micrometers (ASTM B 659, ASTM B 487) The plating thickness requirement identified above represents the minimum value and applies to all significant surfaces unless otherwise specified on

12、the Engineering Drawing. In case of dispute, the thickness measurement umpire method shall be metallographic sectioning per ASTM B 487. 3.3.3 Corrosion Resistance (SAE/USCAR-1, ASTM B 117) 3.3.3.1 Fasteners shall be tested and evaluated in accordance with SAE/USCAR-1, both in the as-plated, trivalen

13、t chromium and sealed condition (as-processed) and after being held at 120 C for 4 hours (baked), and shall pass the number of hours specified in the table below. See WX100 for additional information. 3.3.3.2 Parts other than fasteners shall be tested in accordance with ASTM B117, both in the as-pla

14、ted, trivalent chromium and sealed condition (asprocessed) and after being held at 120 C for 4 hours (baked). Parts shall show no single ferrous corrosion spot larger than 1.5 mm in diameter, and shall not exhibit ferrous corrosion overall exceeding 0.1%, per ASTM D 610, grade 8, after the number of

15、 test hours specified in the table below.

16、WSS-M99A3-A) Parts processed to this specification shall be free from the detrimental effects of hydrogen embrittlement or other factors which result in brittleness. All parts shall meet the requirements of WSS-M99A3-A. 3.4.1 If hydrogen embrittlement relief via heat treatment is specified, post tre

17、atments will be performed after heat treatment. 4. GENERAL INFORMATION The information given below is provided for clarification and assistance in meeting the requirements of these specifications. 4.1 REFERENCE DOCUMENTS The following documents are referenced in these specifications: ASTM B 117 ASTM D 610 WSS-M99A3-A ASTM B 487 QS-9000 WSS-M99P9999-A1 ASTM B 659 SAE/USCAR-1 WSS-M99P1111-A 4.2 WORLDWIDE FASTENER COATINGS When used for Worldwide Standard Parts, the Worldwide Fastener Coating suffix for WSSM21P17- B3 is S437, and the suffix for WSS-M21P17-B4 is S437M.
