所谓所谓热喷涂技术，就是在金属表面上将金属、合金或复合材料通过热源把它加热熔化，并在高速焰流中喷射到工件表面形成涂层，使工件表面具有耐磨、耐腐蚀、抗高温氧化等特殊性能的表面处理技术。所谓传统的高速复卷机辊体是用A3无缝钢管和HT200单一材料来制造的，其强度、耐
The so-called thermal spray technology, is the metal surface of the metal, alloy or composite material through the heat to melt it, and in the high-speed flame jet to the workpiece surface coating, the workpiece surface with wear resistance, corrosion resistance, resistance High temperature oxidation and other special surface treatment technology. The so-called traditional high-speed Winder roll body is made of A3 seamless steel pipe and HT200 single material, its strength, resistance
