Repair Technique of Protective Layer for Corrosion Surface of Compressor′s Metal Parts

The repair of corrosion surface of compressor′s metal parts including the rotor of screw compressor,impeller and cylinder,etc,is concerned by the industries.According to the damage situation,the rotor of screw compressor and impeller could be repaired by laser alloy technology.The keys for promoting green reproduction of metal parts of compressors are to develop industrial repair materials and to increase technical service-oriented enterprises with thermal spray and laser surface alloying technology for the metal parts of compressors.
