一、概述1.机械零件表面预处理的重要性机械零件表面预处理是零件制造或维修过程中的重要工序,是零件表面尺寸精度、几何形状精度、粗糙度检测,表面强化性能、力学性能检测,表面腐蚀、磨损、疲劳、划伤、粘着情况检测的前提,也是零件表面处理质量的前提.零件表面预处理的质量,直接影响零件表面分析、表面测量、表面加工、表面处理及整机或部件的装配质量,进而影响零件与整机的可靠性与寿命. I. Overview 1. The importance of mechanical parts surface pretreatment Mechanical parts surface pretreatment is an important part of the manufacturing process or maintenance process is part surface dimensional accuracy, geometric shape accuracy, roughness testing, surface hardening, mechanical properties testing , Surface corrosion, wear, fatigue, scratches, adhesion conditions testing premise, but also the premise of the quality of parts surface treatment. Parts surface pretreatment quality, a direct impact on the parts surface analysis, surface measurement, surface processing, surface treatment and machine or Parts of the assembly quality, thereby affecting the reliability of parts and 整机 and life expectancy.
