蒸汽热处理是把工件放在通入水蒸汽的爐子里,在一定的温度范圍內(300～700℃)保温一定时間,使工件表面产生一层細致的氧化膜。这种氧化膜对不同的材料,具有不同的优良性質。目前,蒸汽热处理广泛应用于黑色金属和有色金属。譬如用它来提高硬質合金、高速鋼工具的寿命,提高碳鋼、铸鉄件 Steam heat treatment is to put the workpiece into the steam into the furnace, in a certain temperature range (300 ~ 700 ℃) insulation for a certain period of time, so that the workpiece surface layer of meticulous oxidation film. This oxide film has different good properties for different materials. Currently, steam heat treatment is widely used in ferrous and non-ferrous metals. For example, use it to improve the life of carbide tools, high-speed steel tools, improve carbon steel, castings pieces
