中文摘要:通过改变电子束处理参数对表面进行轰击,检测并分析处理后的金属表面粗糙度和形貌。结果表明,实验材料粗糙度随轰击次数的增加呈现先升高再降低的变化趋势;形成这一变化的原因是由能量沉积与火山坑的面密度共同作用的结果。
英文摘要:Using HCPEB system disposing the surface of 40Cr steel, through changing the treated parameters, the surface roughness and morphology were tested and analyzed. The results show that the surface roughness increases with the increase of the number of bombardment first and then reduces. The formation of this change is caused by energy deposition and the surface density of volcano eruption.
