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 thermal spraying technology was used to spray wear-resistant anti-corrosive E10 resin coating material on the polished rod material of pumping unit and simulate the working environment of polished rod of pumping unit. With Si4N3, GCr15 and TC4 as the three pairs of grinding materials, the speed was 0.4 m / s (0.2-0.4 m / s) and working pressure of polished rod surface 4 MPa. The friction and wear test of the sucker rod material and the coating material was carried out through HT-1000 high temperature friction and wear test. The results show that the coefficient of friction of polished rod of pumping unit is 0.86, 0.57 and 0.23, respectively, compared with that of Si4N3, GCr15 and TC4. However, the coefficient of friction of coating material is 0.164, 0.191 and 0.218. Coating material can reduce the friction coefficient, especially with Si4N3, GCr15 two kinds of materials on the grinding, microscopic analysis by scanning electron microscopy found that the coating and the substrate close together, good strength.
