摘要
利用１０ｋＷ连续ＣＯ２激光束对熔敷在中碳钢表面上的Ｆｅ４０Ｎｉ３６Ｃｒ２Ｓｉ８Ｂ１４合金进行了表面非晶化处理，对已处理表面进行了扫描电镜（ＳＥＭ）、透射电镜（ＴＥＭ）和电子衍射（ＥＤＰ）的检测分析，发现无论在单条激光处理区，还是在多条处理的搭接区均获得了非晶结构，与之共存的还有微晶组织．处理中非金属无素的烧损是出现微晶的原因．
A sample of middle carbon steel coated with Fe40Ni36Cr2SiCr2Si8B14 alloy was glazed by 10kW continuous CO2 laser. After laser glazing the structures of specimens was studied and examined by SEM, TEM and EDP.Its shown that a amorphous structrure has been produced not ouly at the zone of glazing oneway trip but also at the the glazing overlap. Because of the loss of nonmetallic elements, the microcrystallins exist in company with the amorphous structure.
