The aim of this study is to show how electron beam remelting affects the structure and properties of CoCrW coatings. As described in the paper, CoCrW powders are plasma sprayed onto nickel substrates and a modified electron beam welder is used to remelt the deposits. The effects of the treatment are assessed via SEM and XRD analysis, wear testing, and hardness measurements. In summary, electron beam remelting improves a number of coating properties including adhesion strength and fretting wear resistance. It also eliminates oxide inclusions and lamellar structures and reduces layer porosity. Paper includes a German-language abstract.
