粉末火焰喷涂是一种基本的热喷涂方法 ,它利用了气体燃烧火焰为高温热源的特点 ,将耐蚀、耐磨性能均较强的自熔性合金粉末喷向金属工件 ,在工件表面形成一定厚度的保护层 ,以提高工件耐腐蚀、耐磨损性能。在抽油泵柱塞表面实施喷涂工艺 ,可显著地提高其使用寿命。其工艺流程为表面预处理、预热、预喷粉、喷粉、重熔、热校直等 ,主要设备有表面清理设备、喷涂机床、喷涂枪、重熔枪、热校直机等。
Powder flame spraying is a basic thermal spraying method, which takes advantage of the characteristics of gas combustion flame as high temperature heat source, spraying the self-fluxing alloy powder with strong corrosion resistance and abrasion resistance to the metal workpiece to form a certain surface on the workpiece Thickness of the protective layer to improve the workpiece corrosion resistance, wear resistance. In the pump plunger surface spraying process, can significantly improve its service life. The process for the surface pretreatment, preheating, pre-dusting, dusting, remelting, thermal straightening, the main equipment surface cleaning equipment, spraying machine tools, spray gun, remelting gun, heat straightening machine.
