一、氧-乙炔焰合金粉末的表面强化技术近几年来,国内外广泛应用的金属粉末复盖防护技术是一项强化零件表面以延长机件使用寿命的新工艺。其中氧-乙炔火焰法的应用尤为广泛、实用。它具有设备简单、操作方便、工艺灵活等显著优点,适用于大部分的碳钢、合金钢、不锈钢、铸铁和部分有色金属制成的零件。因此已在电力生产中发挥了一定的作用。氧-乙炔焰粉末复盖防护技术,可分为喷熔和喷涂两种工艺。喷熔是利用氧-乙炔火焰
First, the oxygen - acetylene flame alloy powder surface hardening technology In recent years, widely used metal powder covering at home and abroad protection technology is to strengthen the surface of parts to extend the service life of the new piece of machinery. Which oxy-acetylene flame method is particularly widely used, practical. It has the advantages of simple equipment, convenient operation and flexible technology. It is suitable for most parts of carbon steel, alloy steel, stainless steel, cast iron and some non-ferrous metals. So it has played a certain role in electricity production. Oxygen - acetylene flame powder cover protection technology can be divided into two kinds of spraying and spraying process. Spray melting is the use of oxygen - acetylene flame
