Abstract
Cobalt-phosphorous-boron coated objects and processes for production of the same. The coatings are wear resistant and may have several characteristics that render them suitable for applications in certain industries, such as the aerospace industry. The manufacturing process for the coated objects is free of hexavalent chromium fumes generation. The process of manufacture includes the steps of at least partially submerging a metal object as a cathodic element into a plating bath. The plating bath includes an aqueous solution of cobalt ions, chloride ions, phosphate ions, phosphite ions and boron-containing ions. The plating bath may have a pH in the range from about 1.0 to about 1.8. Current flows between an anode in the plating bath and the cathodic element in contact with an object to be coated for a time sufficient to deposit a cobalt-phosphorous-boron coating on the object. The current continues to flow until a coating of desired thickness is obtained.
