摘　　要：采用热喷涂技术将耐磨防腐E10树脂涂层材料喷涂在抽油机光杆材料上,并模拟抽油机光杆工作环境,以Si4N3、GCr15、TC4为三种对磨材料,速度为0.4 m/s(0.2～0.4 m/s),光杆表面工作压力4 MPa,经过HT-1000型高温摩擦磨损试验对抽油机光杆材料和涂层材料进行摩擦磨损测试。结果表明,与Si4N3、GCr15、TC4三种对磨材料对磨时,抽油机光杆的摩擦系数分别为0.86、0.57和0.23;而带有涂层材料的摩擦系数却为0.164、0.191和0.218。涂层材料能降低摩擦系数,特别是与Si4N3、GCr15两种材料对磨,经扫描电镜微观分析发现,涂层与基体结合紧密、强度好。The wear-resistant and anti-corrosion E10 resin coating materials was sprayed onto the polished rod of pumping unit by thermal spraying.Simulating the working condition of the polished rod,taking the Si4N3,GCr15 and TC4 as the partner samples,0.4 m/s as the speed,4 MPa as the pressure,the friction and wear performances of the polished rod and coating materials were tested on HT-1000 type high temperature friction and wear tester.When coupled with Si4N3,GCr15 and TC4,friction coefficients of the polished rod are 0.86,0.57,0.23 respectively;friction coefficients of coating materials are 0.164,0.191,0.218,respectively.The results indicate that the coating materials can reduce the friction coefficient,especially coupled with Si4N3,GCr15.The coating material is closely combined with the matrix without crack.
