氧乙炔焰金属粉末喷涂与喷焊工艺,由于具有工件加热温度低、涂焊层耐磨、设备简单、操作方便和效率高等优点,已被用于修复磨损的零、部件或作为预防性保护层,以提高零、部件易损表面的使用寿命。喷涂、喷焊工艺所用的材料为镍基、铁基、钴基、铜基等类型的合金粉末。这些合金粉末含有多量的镍、钴,以及不同含量的铬、硅、硼、铝等元素,使涂、焊层实现切削加工时刀具严重磨损。尤其是喷焊层,表面硬度一般均在 HRC 45以上(有高达 HRC 66的),
Oxyacetylene flame metal powder coating and spray welding process, due to the workpiece with low heating temperature, wear-resistant coating, simple equipment, easy operation and high efficiency, has been used to repair wear and tear of zero, parts or as a preventive protective layer , In order to improve the service life of zero, vulnerable parts of the surface. Spray, spray welding process used by the material for the nickel-based, iron-based, cobalt-based, copper and other types of alloy powder. These alloy powders contain a large amount of nickel, cobalt, and different amounts of chromium, silicon, boron, aluminum and other elements, so that the coating, welding layer cutting tool to achieve serious wear and tear. In particular, spray coating, the surface hardness are generally above HRC 45 (up to HRC 66),
