用常规的和新发展的抗滚动接触疲劳试验装置来确定不同类型的轴承钢上沉积几种硬质表面镀层的抗动态粘着和鳞剥(或称散裂),将化学气相沉积(CVD)、反应溅射(RS)、活性反应蒸镀和电镀的硬质镀层镀在常规的和粉末冶金工艺制成的作轴承滚动元件的材料之滚动接触疲劳杆上。这个镀膜和测量计划的目的是为了阐明沉积类型和温度对不同钢底材的变形的影响,以及使用标准化的试验技术将滚动接触粘着定量化。数据表明,在镀层粘结力和变形趋向之间有很大的差别,两者都是随着镀层类型和沉积温度以及钢的显微结构而变化的。发现CVD CrC-TiC复合硬质镀层在赫芝负荷达4.83×10~9Pa(原文错为2.79Gpa——译者注)时显示出特别非凡的抗粘着和鳞剥。
Conventional and newly developed anti-rolling contact fatigue test devices are used to determine the resistance to dynamic adhesion and scaling (or spalling) of several hard surface coatings deposited on different types of bearing steel. Chemical vapor deposition (CVD) Reactive Sputtering (RS), Reactive Vapor Deposition, and Electro-Plating Hard Plating is applied to the Roller Contact Fatigue Rods of the materials of the bearing rolling elements made by conventional and powder metallurgical processes. The purpose of this coating and measurement program is to clarify the effect of deposition type and temperature on the deformation of different steel substrates and to quantify rolling contact adhesion using standardized test techniques. The data show that there is a large difference between the coating adhesion and the tendency to deform, both of which vary with the type of coating and the deposition temperature and the microstructure of the steel. The CVD CrC-TiC composite hard coating was found to exhibit particularly remarkable resistance to sticking and scaling when the Hertzian load reached 4.83 x 10-9 Pa (source text incorrectly 2.79Gpa).
