Abstract:
A coating which improves the wear performance of a part is described. The coating is applied over an article such as a part or a workpiece using an electroplating process. The coating broadly includes a cobalt material matrix with a hardness of at least 550 HV and a plurality of carbide particles distributed throughout the cobalt material matrix. The cobalt material matrix may be a cobalt-phosphorous alloy. The particles interspersed throughout the matrix may be chrome carbide or silicon carbide particles.
