氧-乙炔火焰喷焊是一种新的表面硬化工艺。它采用专门的氧-乙炔喷焊焊炬把具有各种特殊性能(如耐磨、耐蚀)的自熔性合金粉末喷洒到工件的表面并进行再熔化处理,通过合金粉末及基体的相互熔敷,形成一种具有冶金结合的薄层。与通常的堆焊方法相比较,它具有熔深浅,喷焊层表面光洁,厚度可精确控制至0.1毫米,从而大大地减少切削加工量等;同时,由于设备简单,凡具备氧气和乙炔的地方都可采用,工艺操作不需要特殊的培训便能掌握,因此近年来发展很快。
Oxygen acetylene flame spray welding is a new surface hardening process. It uses a special oxygen - acetylene welding torch to have a variety of special properties (such as wear-resistant, corrosion-resistant) of the self-fluxing alloy powder sprayed onto the surface of the workpiece and re-melting process, through the alloy powder and matrix mutual melting Deposited to form a thin layer with metallurgical bonding. Compared with the usual surfacing method, it has a shallow penetration, smooth surface spray coating, the thickness can be accurately controlled to 0.1 mm, thereby greatly reducing the amount of cutting, etc .; the same time, due to the equipment is simple, where there is oxygen and acetylene Can be used, the process does not require special training operations will be able to grasp, so the rapid development in recent years.
