Abstract:

Attempts were made to increase the ceramic content of the electrodeposited chromium-base cermet coating developed previously. Many plating variables, such as current density, solution temperature, plating solution composition and flashing time and current density, were investigated. The use of a dispersing agent and the effect of different concentrations of ceramic in the plating solution on the amount of ceramic occluded in the coating were studied. It was found that increasing the ceramic concentration to 0.133 ml per ml of plating solution resulted in a coating containing 5 ceramic.
