影响磨料磨损的内部因素内部因素包括材料的成分、微观组织特征及机械性能等。材料的成分、微观组织和机械性能是互相联系、互有影响。总的说起来,造成材料磨料磨损的原因(除腐蚀外)主要有两个,一个是塑性变形,一个是断裂。在某一特殊的磨损条件下,凡能控制住磨损发生根源的某种成分,微观组织或性能,它们都对耐磨性有利。由于磨损发生的复杂性,所以某种参数在某一磨损条件下有利而在另一种条件下就不一定有利,某一种组成物,(例如残余奥氏体),在一定
Internal Factors Affecting Abrasion Wear Internal factors include material composition, microstructure and mechanical properties. Material composition, microstructure and mechanical properties are interrelated and influence each other. In summary, there are two main causes of material abrasion (except corrosion), one is plastic deformation and the other is fracture. In a special wear conditions, who can control the root causes of wear and tear of a composition, microstructure or properties, they are good for wear resistance. Due to the complexity of wear and tear, a certain parameter is advantageous under a certain wear condition but not necessarily under another condition. When a certain kind of composition (for example, retained austenite)
