Application of 500kV Ultra High Voltage E.B. to Surface Modification of Carbon Steel

摘要

An alloy surface layer with homogenized distribution of alloying elements was obtained by using a high voltage electron beam with energy density control together with Ni-Cr alloy powder for thermal spraying. There was little spattering of materials during electron beam irradiation and no porosity inside the melted layer. The feasibility of high quality surface modifications using the high voltage electron beam was demonstrated.
