前言应用电弧喷涂技术修复零件表面的磨损与划伤有突出的优点：①零件不需预热。尤其给不便预热的大型设备零件的修复带来了极大方便；②喷涂时工件受热个，不存在象堆焊那样的热变形、热裂纹、热影响区及高应力；③修复层厚度大，单边喷涂可达smm以上；①喷涂层与基体结合强度
Preface The application of arc spraying technology to repair parts surface wear and scratch have outstanding advantages: ① parts without preheating. Especially for the inconvenience to preheat the repair of large equipment has brought great convenience; ② When the workpiece is heated spray a, there is no such as surfacing as thermal deformation, hot cracks, heat affected zone and high stress; ③ repair layer thickness , Unilateral spraying up to smm above; ① spray coating and substrate bonding strength
