污染引起的损害（续上期）污染物颗粒具有各种形状和尺寸并由各种材料构成。大多数是磨粒性的，所以当它们与表面相互作用时，它们从元件中的关键表面上犁削和切削出碎片。这种磨粒磨损和表面疲劳约占退化失效的９０％。１失效的类型由污染所引起的失效分为三大类：（１）... Pollution-Induced Damage (Continued) Pollutant particles come in various shapes and sizes and consist of a variety of materials. Most are abrasive, so when they interact with the surface, they plow and chip away from the critical surfaces in the component. This abrasive wear and surface fatigue account for about 90% of the degradation failure. 1 types of failure caused by pollution failure is divided into three categories: (1) ...
