热喷涂(焊)新工艺是当前金属零部件表面强化及补修用的一项先进技术,已列为我国今后推广的重点项目之一。它是利用氧乙炔焰或等离子弧等能源,将具有特殊性能的合金粉末或非金属(金属陶瓷)粉末,均匀地喷敷到机械零部件的表面上,形成一层薄而致密的具有耐磨、耐蚀、耐幅射、耐热抗氧化、隔热、绝缘等综合优良性能的保护层,使之失效工件得 Thermal spraying (welding) new technology is the current surface of metal parts and repair with an advanced technology, has been listed as China’s future promotion of one of the key projects. It is the use of oxygen acetylene flame or plasma arc and other energy sources, will have special properties of alloy powder or non-metallic (cermet) powder evenly sprayed onto the surface of mechanical parts to form a thin and dense with wear , Corrosion resistance, radiation resistance, thermal oxidation resistance, insulation, insulation and other comprehensive performance of the protective layer so that the failure of the workpiece was
