  • Processes for the electrodeposition of composite coatings
    Patent number: 4305792
    Abstract: A process of and apparatus for coating an article with a layer of metal incorporating particles. The article is placed in a barrel together with the particles and the barrel is placed in a plating bath and rotated therein. The barrel has an opening covered by a cover which is pervious to the solution but impervious to the particles. The article is thus flowed over by solution within the barrel which can have a high concentration of particles but there are no particles in the part of the bath outside the barrel. The process may be electroless or electrolytic. In the latter case, the anode is preferably outside the barrel.
