Abstract:Using coal solid waste, the fly ash composite coating was prepared on the surface of pure copper by plasma spray. The morphologies were observed with SEM, and phase composition of the composite coating were analyzed with XRD. The properties of thermal shock，oxidation resistance，abrasive wear and erosion wear of the composite coating were investigated by thermal shock test，anti-oxidative test，abrasive wear test and erosion wear test. The results show that the coating is dense and has high bonding strength. New phases, such as 3Al2O3？2SiO2, AlB2 and Al9Si, are produced too. The coating has very excellent thermal shock property, and the times of thermal shock is 74. The coating has excellent oxidation resistance and wear resistance. Compared with the base of pure copper, the oxidation resistance, abrasive wear and erosion wear of the coating are improved by 3.14, 6.16 and 7.48 times, respectively.
Key words: plasma spray; fly ash composite coating; pure copper; erosion wear
