This paper discusses wear life of laser cladding samples with the aid of the theory of contact fatigue wear. The experiment and analysis showed that it is feasible to calculate wear life of laser cladding samples with the aid of the theory of contact fatigue wear.
利用接触疲劳磨损理论讨论激光熔覆试样的疲劳磨损寿命问题.试验结果表明：在本试验条件下，接触疲劳磨损理论用于激光熔覆层的寿命估算是可行的。
So the systems analysis of the roller's wear mechanism and contact fatigue and the research of contact stress and wear rule have the important meaning on controlling geometry precision, the board form and surface quality and prolonging the roller's using life.
因此对轧辊磨损机理和接触疲劳的系统分析，研究其接触应力和磨损规律，对于控制轧件的几何精度、板形和表面质量，延长轧辊使用寿命等有着重要的意义。
Magnetic bearings ( MB) can support a rotor without contact. This will eliminate the mechanical friction and wear, and reduce the damage to blood and the probability of hemolysis and thrombus, and also increase the use life of blood pumps.
磁悬浮轴承能够实现转子的无接触悬浮支承，消除了轴承处的机械摩擦和磨损，降低了对血液的破坏作用，也降低了溶血和血栓的发生几率，延长了整机寿命。
