摘要:
在挤压轮表面,用等离子技术喷涂Al2O313%TiO2涂层。利用XRD、SEM和EDS等技术对Al2O313%TiO2涂层微观组织、形貌和物相成分进行表征,运用维氏显微硬度计对基体和涂层的显微硬度进行了测试,用高温摩擦磨损试验机对Al2O313%TiO2涂层的耐磨损性能进行了评价。结果表明,Al2O313%TiO2涂层中γAl2O3和αAl2O3共存,以γAl2O3为主,涂层表面有Al2O3白色颗粒存在,涂层致密度较好,其表面显微硬度为975 HV,耐磨损性能要明显优于H13钢,有效的提高了挤压轮的使用寿命。
Abstract:
The microstructure and high temperature wear resistance ofplasma sprayed Al2O313%TiO2 coating on the surface of extrusion wheel.The microstructure,morphology and phase composition were analyzed by XRD,SEM and EDS,and microhardness of substrate and AT13 coating were tested by Vickers Microindentor,and the wear resistance of Al2O313%TiO2 coating was evaluated byfriction and wear testing machine.The results indicate that the Al2O313%TiO2 coating contains γAl2O3 and αAl2O3,mainly consists of γAl2O3,with white particles Al2O3 on its surface,as well as better densityof the coating,the surface hardness was 975 HV,the wear resistance of Al2O313%TiO2 coating was better than H13 which contributed to the improvementof the serviceable life of the extrusion wheel.
