Laser Treating of Layer Coated with Fe-Ni-Cr-Si-B Alloy on Carbon Steel

摘要: 利用10kW連續CO2激光束對熔敷在中碳鋼表面上的Fe40Ni36Cr2Si8B14合金進行了表面非晶化處理,對已處理表面進行了掃描電鏡(SEM)、透射電鏡(TEM)和電子衍射(EDP)的檢測分析,發現無論在單條激光處理區,還是在多條處理的搭接區均獲得了非晶結構,與之共存的還有微晶組織.處理中非金屬無素的燒損是出現微晶的原因.Abstract: 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.
