摘要
为优选透平式能量回收一体机关键零部件耐磨材料,以TC4钛合金与共聚甲醛、均聚甲醛、PEEK及改性PEEK组成的配对摩擦副作为研究对象,利用立式万能摩擦磨损试验机开展干摩擦、纯水及海水环境介质下配对材料的摩擦磨损试验,定量获得各摩擦副的摩擦因数和磨损量,并对摩擦试样的表面形貌进行分析。结果表明:在干摩擦环境下共聚甲醛摩擦因数和磨损量最小,在纯水和海水环境下改性PEEK摩擦因数和磨损量最小;TC4钛合金与均聚甲醛、共聚甲醛、PEEK配副时磨损机制为黏着磨损,主要表现形式为涂抹和擦伤,TC4与改性PEEK配副时磨损较轻微,主要表现形式为轻微磨粒磨损。
In order to select the wear-resistant materials of the key parts and components of integrated turbine energy recovery machine,the friction pairs composed of TC4 titanium alloy with POM-C,POM-H,PEEK and PEEK-PVX were taken as the research object,the tribological behaviors in dry friction,pure water and seawater environments were studied on the vertical universal friction and wear testing machine.The friction coefficient and wear amount of each friction pair were obtained quantitatively,and the surface morphology of the friction samples was analyzed.The results show that in dry friction environment,the friction coefficient and wear amount of POM-C samples are the minimum,in the pure water and seawater environment,the friction coefficient and wear amount of PEEK-PVX samples are the minimum.The wear mechanism of TC4 titanium alloy with POM-H,POM-C and PEEK is adhesive wear,mainly in the form of smear and abrasion.The wear of TC4 titanium alloy with PEEK-PVX is slight,mainly in the form of slight abrasive wear.
