氧乙炔焰金属粉末喷涂是将金属粉末通过氧乙炔火焰加热至熔化或达到高塑性状态后,喷射并粘结到处理过的工件表面,从而形成牢固的结合涂层的一种喷涂方法。此法除具有工件加热温度低(100℃),涂层耐磨(提高2～3倍),用途广等优点外,该工艺最大的特点是设备简单,操作容易,修复速度快,和经济效果好。它主要用于工件磨耗区域的预防性保护和修复。喷涂的涂层由过渡层和工作层组成。过渡层能与基体达到良好的结合(结合强度达3.25
Oxyacetylene flame metal powder coating is the metal powder through the oxyacetylene flame heated to melt or reach a high plastic state, the jet and bonded to the surface of the workpiece to be processed, forming a strong bonding coating of a spraying method. In addition to this method has the workpiece heating temperature is low (100 ℃), wear-resistant coating (increased by 2 to 3 times), the advantages of wide use, the biggest feature of the process is simple equipment, easy operation, repair speed, and economic results it is good. It is mainly used for preventive protection and repair of worn parts of the workpiece. Sprayed coating consists of a transition layer and a working layer. The transition layer can be combined with the substrate to achieve a good (combined strength of 3.25
