利用煤炭固体废弃物，采用等离子喷涂技术，在工业纯铜表面制备粉煤灰复合涂层。利用SEM和XRD分析涂层的组织形貌和物相组成，通过热震实验、抗氧化性实验、磨粒磨损实验、冲蚀磨损实验分别测试涂层的热震性、抗氧化性、磨粒磨损性和冲蚀磨损性。结果表明：涂层表面致密，结合性良好，且有3Al 2 O 3?2SiO 2、AlB 2和Al 9 Si等新相产生；涂层具有良好的热震性能，热震次数达到74次；涂层具有良好的抗氧化性和耐磨性，其抗氧化性、磨粒磨损性和冲蚀磨损性比基体分别提高了3.14倍、6.16倍和7.48倍。
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 3Al 2O3?2SiO2, AlB2 and Al9 Si, 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.
