【摘要】 ZGMn13冲击板的失效方式为不同角度的粒子撞击和冲刷,其表面可以分为三个典型的磨损区域:低角度撞击区、高角度撞击区和冲刷区。详细分析了该三个磨损区域的磨损机理。对次表面分析的结果表明,在低角度撞击和冲刷条件下,高锰钢未能充分加工硬化,耐磨性提高有限。更多还原

【Abstract】 The granule impact in different angle and abrasion were main failure pattern with ZGMn13 fan blades on which was divided into three typical wear Zones: Low-angle impact Zone,High-angle impact Zone and abrasion Zone.The wear mechanism in each Zone was analysed detailly.The Sub-surface analysis showed that in condition of low-angle impact and abrasion the fan blades of ZGMn13 Were not hardening by deformation fully So that its wearproof ability increase finitely.更多还原
