Abstract: Major improvements in Mechanical Barrel Plating are virtual elimination of expensive glass impact media, elimination of larger size glass balls such as 3 mm and 5 mm, with replacement by assorted pieces of small high density rubber or equivalent non-staining pieces acting to stay inside the tumbling mass to lift the article in the charge and to interrupt streamline flow to cause random disoriented movement whereby complete uniform coverage of the articles being coated is achieved.The further improvement resulting from the elimination of large masses of small glass beads and balls creating an open permeable mix permitting easy access of the plating metal powder such as Zinc to the article being coated.

Abstract: The invention relates to the use of voltaic cells in both leachable and non-leachable vehicles which is a unique concept. It relates to the use of hard abrasive vehicles. It relates to the use of vehicles that will permit the voltage to provide a current when the circuit is closed. The concept of a multiplicity of voltaic cells generating a voltage within the paint makes it possible to eliminate toxic ingredients such as Copper, Copper salts such as Cuprous Oxide, Mercury and its salts and other toxic ingredients such as Tributyl Tin Oxide with great benefit to the environment. The non-leachable vehicle eliminates or reduces the loss of electromotive force generating within the paint so that the paint is capable of remaining effective for years instead of the usual life of one growing season.

Abstract: A new composition for promoting mechanical plating, a process using the composition and the resulting article are disclosed. The new composition employs an acidic or alkaline flux and at least one silicone compound. When used in combination with a finely divided metal under mechanical plating conditions, exceptional metal coatings are produced. Also disclosed is the use of metal cleaning agents in the composition to further enhance the results obtained from the mechanical plating process. In addition, foaming agents may be used to generate a foam which aids in making the plating slurry transportable.
