3、ALUMINUM ALLOY - EXTERIOR OR INTERIOR 1. SCOPE These specifications define performance requirements for bright, organically colored, or electrolytically colored anodized aluminum finishes. 2. APPLICATION These specifications were released originally where a bright, combination colored and bright, an
4、d fully colored decorative and protective anodic finish is required on aluminum and aluminum alloy surfaces. Levels of performance are defined as follows: WSB-M4P9-B1 Bright interior part applications, e.g., bezels, moldings. WSB-M4P9-B2 Bright exterior part applications, e.g., bodyside, rocker, win
5、dow moldings, bumpers, etc. WSB-M4P10-B1 Colored interior part applications subjected to minimal ultraviolet (sunlight) and abrasion environments. WSB-M4P11-B1 Colored interior or exterior part applications that must withstand ultraviolet and abrasion exposures, e.g., bodyside, window moldings, etc.
6、 CAUTION: Based upon production and accelerated laboratory testing experience, anodic coatings are temperature sensitive and will craze (i.e., crack) when exposed to temperatures approaching 90 C and higher. Therefore, anodized aluminum parts must be masked prior to paint repair oven exposure. 3. RE
7、QUIREMENTS All requirements identified for each specification must be met to achieve acceptable field durability. No one requirement, exclusive of others, is capable of insuring satisfactory performance. Any deviations to the requirements of these specifications may be subject to additional performa
8、nce requirements. ENGINEERING MATERIAL SPECIFICATIONWSB-M4P9-B1/B2WSB-M4P10-B1WSB-M4P11-B1Printed copies are uncontrolled Copyright 2003, Ford Global Technologies, Inc.

9、tandard Requirements For Production Materials (WSS-M99P1111-A). 3.2 COMPOSITION OF THE ANODIC COATING The coating desired shall consist essentially of transparent hydrated aluminum oxide of uniform density and film thickness. Parts anodized and sealed to the WSB-M4P10-B1 specification shall have a s
10、uitable organic dye and/or pigment applied to achieve the desired appearance. The coloring of parts produced to the WSB-M4P11-B1 specification is achieved by the electrolytic deposition of metal salts in the anodic coating. 3.3 METAL FORMING All parts directly exposed to the exterior environment tha
11、t are processed to the requirements of these specifications shall be formed (fabricated) prior to anodizing to prevent crazing of the anodic coating. 3.4 ANODIC COATING THICKNESS, min (ASTM B 659) WSB-M4P9-B1 2.5 m WSB-M4P10-B1 2.5 m WSB-M4P9-B2 7.5 m WSB-M4P11-B1 7.5 m Note: The WSB-M4P11 minimum t
12、hickness requirement for both exterior and interior applications is 7.5 m because the appearance is coating thickness related. 3.5 ANODIC COATING WEIGHT, min (ASTM B 137) WSB-M4P9-B1 6.2 g/m2WSB-M4P10-B1 6.2 g/m2WSB-M4P9-B2 18.6 g/m2WSB-M4P11-B1 18.6 g/m2Note: The coating weight values obtained from
13、 the acid dissolution test sample (para 3.6) may be used for this test. 3.6 ACID DISSOLUTION TEST (A.D.T.), 6.0 max. (FLTM BQ 007-02) 3.7 ACCELERATED CORROSION RESISTANCE (CASS), 16 h There shall be no base metal (white corrosion) following the CASS test. ENGINEERING MATERIAL SPECIFICATIONWSB-M4P9-B

Page 3 of 3 3.8 WEATHERING RESISTANCE A demonstration of conformance to the following weathering resistance requirements is mandatory for all new bright or color anodizing suppliers seeking sou
15、rce approval and for all new colors prior to release by Styling. These requirements do not apply to production parts, either for initial sampling or routine control. 3.8.1 Weatherometer (ASTM D 3361) No color change of bright anodized coatings and no fading of colored coatings greater than originall
16、y approved. WSB-M4P9-B1 1000 h WSB-M4P9-B2 1000 h WSB-M4P11-B1 1000 h WSB-M4P10-B1 500 h 3.8.2 Florida Exposure Anodic coatings shall show no more checking, color change, chalking, or dulling than the originally approved samples when exposed as follows: WSB-M4P9-B1 12 months in Miami, Florida, WSB-M4P9-B2 facing south at a 5 angle WSB-M4P11-B1 off horizontal. WSB-M4P10-B1 6 months under glass (see AATCC Test Method 16C for type of glass) in Miami, Florida, facing south at a 45 angle.
