11、 2017 by Navistar, Inc. JUNE 2017 Page 2 of 7 4.1 Coating Requirements PVD Coating systems on plastic parts typically consist of three layers. The first layer applied to the plastic base is an ultraviolet light (UV) curable base coat. The second layer is a thin layer of vapor deposited metal. The th
12、ird layer is a UV resistant, clear, organic, topcoat. The performance requirements given below are expected of the composite coating not individual layers. Systems other than those specified which demonstrate satisfactory performance may be approved by Navistar Materials Engineering Laboratory. 4.2

21、ubjected to three complete cycles consisting of the following sequence: 1) 85C (185F) for 30 minutes. 2) -34C (-30F) ethylene glycol/H2O bath for 30 minutes. Parts shall be transferred immediately from one environment to the other with no time allowed between cycles. There shall be no evidence of pl
22、ating and/or plastic failure due to cracks, crazing, blistering, corrosion, and loss of plating adhesion. After completion of the satisfactory number of prescribed thermal cycles and corrosion test, as well as the thermal shock test, parts passing these tests shall be scribed with an “X“ through the
23、 plating to the plastic surface. A strip of adhesive tape (suitable for ASTM D3359 testing) 1.9 cm (3/4 in) wide, shall be applied to the scribed “X“. The tape shall be pulled at 90 to the surface and the part examined for lifting of the plating. Evidence of loss of adhesion shall be cause for rejec
24、tion. NOTE: Test samples are PC/ABS plaques either 4” X 4”, 4” X 6”, or 12” X 12. Some analysis may occur from molded parts. Samples should be cloth wiped to remove airborne particulate material. Coated samples may be aged at Room Temperature at 50% 5% relative humidity prior to onset of analysis. 5
25、.0 QUALITY The plated part shall have a bright or satin finish as specified and a uniform reflective finish. Each plated deposit shall be adherent and free from cracks and foreign material (except for the post nickel strike and the resulting microporous chromium). The surface shall be dense, smooth,
26、 uniform, and free from stains, pinholes, nodules, or any other defects which affect the overall appearance of the plating or its ability to meet the requirements of this specification. 6.0 QUALIFICATION Engineering qualification of sources is required in advance of production shipments. Samples sha
27、ll be accompanied by test data certifying that all requirements of the specification have been met. Suppliers shall submit samples for approval of finish, luster, color and appearance to the Navistar Industrial Design Group. Upon approval, styling master samples denoting the minimum level of accepta
28、ble appearance quality shall be developed and retained by the supplier and the quality department of each using NAVISTAR facility.
