Committee B-8 proudly sponsors this symposium with the thought that the papers will be of great value to engineers and others concerned with materials, processes, and tests involved in the use of electrodeposited metallic coatings. The particular subjects presented are representative of the type of activity with which Committee B-8 is concerned, although they do not cover all subjects on which committee work has been carried out. An all-inclusive presentation would require several days. Thus, Spring's paper on metal cleaning, for example, is important but otherwise typifies standard-practice treatments which have been published on diverse subjects such as: Recommended Practice for the Preparation of High-Carbon Steel, Preparation of Zinc Base Die Castings for Plating, Preparation of Copper and Copper Alloys for Plating, Preparation of Stainless Steel for Plating, and Recommended Practice for Plating on Aluminum. The foregoing partial list of subjects results from the work of one of the subcommittees of Committee B-8. Typical of the work of another subcommittee are Mr. Bowman's paper on luster measurements and Mr. Mendizza's paper on the salt-spray test. Other subjects, either published or under preparation by this same group, involve tests on electrodeposited metallic coatings for thickness, porosity, adhesion, ductility, hardness, and stress. Typifying the work of two other subcommittees are the papers describing performance tests of copper-nickel-chromium combination coatings as well as zinc, cadmium, lead, and supplementary conversion coatings on certain of these metals. The groups concerned with such performance studies are continuing their work and have programs under consideration for other types of metallic coatings.
