【摘要】：为了寻找适合于水液压泵/马达的摩擦副材料,以316 L不锈钢与纯聚醚醚酮树脂、30%玻璃纤维增强PEEK(PEEKGF30)、30%碳纤维增强PEEK(PEEKCA30),PTFE和石墨及碳纤维填充PEEK(PEEKHPV)组成的摩擦副为研究对象,利用MMW-1立式万能摩擦磨损试验机测量摩擦副在水润滑下接触表面的摩擦因数和温度以及试样的磨损量,并通过激光共聚焦显微镜对试件表面磨损形貌进行分析。结果表明:316 L-PEEKHPV摩擦副的摩擦因数、摩擦温升、磨损量均小于其余3组摩擦副,适合作为水液压泵/马达的关键摩擦副材料。316 L不锈钢与PEEKGF30配对时,摩擦机制为涂抹和擦伤,磨损较为严重;与PEEKCA30配对时,摩擦机制为擦伤;与PEEKHPV配对时摩擦机制主要为划伤,磨损较为轻微。
[Abstract]:In order to find suitable for water hydraulic pump / motor side friction, with 316 L stainless steel and pure peek resin, 30% glass fiber reinforced PEEK (PEEKGF30), 30% carbon fiber reinforced PEEK (PEEKCA30), PTFE and graphite and carbon fiber filled PEEK (PEEKHPV) composed of friction as the research object, using MMW-1 vertical universal the amount of side friction and wear under water lubrication contact surface friction coefficient and temperature and sample the friction abrasion testing machine measurement, and through laser scanning confocal microscope on the specimen surface morphology analysis. The results show that: 316, the friction coefficient, friction temperature rise and wear volume of L-PEEKHPV friction pair are all less than those of the other 3 pairs of friction pairs, which is suitable for water hydraulic pump / motor's key friction pairs. When the 316 L stainless steel is paired with PEEKGF30, the friction mechanism is smearing and abrasion, and the wear is more serious. When paired with PEEKCA30, the friction mechanism is abrasion. When PEEKHPV is paired, the main friction mechanism is scratching and wear.
