摘要
选用铝合金和高温合金零件为研究对象,以NaHCO3基微晶粉为喷射介质,利用喷砂设备对其表面污层进行喷射清理。利用光学显微镜、扫描电镜、EDS等分析技术,对喷射清理后的表面形貌、成分进行分析;利用粗糙度仪观察清理后的表面粗糙度。结果表明:采用NaHCO3基微晶粉喷射清理技术能有效去除零件表面积碳、油污、氧化物等污层;采用NaHCO3基介质清理后,零件表面粗糙度仅为传统喷砂介质清理后粗糙度的10%,对零件表面损伤较小。
Aluminum alloy and super alloy parts were taken as the research object,NaHCO3-based microcrystalline powder was used as the injection medium,and sand blasting equipment was used to spray and clean the surface fouling layer.The surface morphology and composition of the blast cleaned parts were analyzed by optical microscope,scanning electron microscope,EDS and other analytical techniques.The roughness meter was used to observe the surface roughness of the blast cleaned parts.The results show that the NaHCO3-based microcrystalline powder blast cleaning technology can be used to effectively remove carbon,oil,oxide and other pollution layers on the surface of parts;after cleaning with NaHCO3-based medium,the surface roughness of the parts is only 10%of that after traditional sand blasting medium cleaning,which has little damage to the surface of parts.
