High current pulsed electron beam
WebHigh current pulsed electron beam (HCPEB) is a new type of surface modification technology [19, 20, 21]. During the instantaneous process of HCPEB bombardment, the higher energy (10 7 –10 9 W/cm 2 ) acts on the surface of the material in a very short time (several microseconds), resulting in extremely rapid heating, cooling, melting, and even … WebMicrostructures of CuCr25 and CuCr50 alloys treated by high current pulsed electron beam (HCPEB) were investigated in this work. The microstructure and solidification behavior of the Cr-rich phases were characterized by scanning electron microscopy (SEM). Results show that a remelting layer of 3~5 μm is formed on the surface of Cu-Cr alloys.
