利用球－盘试验机研究了40Cr钢表面氧氮处理层对添加剂磷酸三甲酸酯作用效果的影响，并利用多种表面分析仪器分析了其机理。结果表明磷酸三甲酚酯与氧氮处理表面配合可取得更好的抗擦伤和抗磨效果，其主要原因是由于40Cr钢经氧氮处理后，其摩擦表面上组成边界润滑膜的化学反应膜和氧化膜均更厚已结构更致密
The effect of the oxygen and nitrogen treatment layer on the effect of the additive phosphoric acid tartrate on the surface of 40Cr steel was studied by ball-plate testing machine. The mechanism was analyzed by using a variety of surface analysis instruments. The results show that tricresyl phosphate with oxygen and nitrogen surface treatment can get a better anti-scratch and anti-wear effect, the main reason is that the 40Cr steel after oxygen and nitrogen treatment, the friction surface composed of the boundary lubrication film chemical reaction membrane Thicker and oxide films are denser and denser
