材料的渗氮一般在500～580℃进行(低温渗氮)。近年来,广泛应用珠光体钢、铁素体-马氏体钢、铁索体钢和奥氏体钢、镍合金和难熔金属(Ti、Mo、Nb、V、Gr等等)的高温渗氮(600～1200℃)。渗氮是在氨、氨和含碳的混合气体(吸热型气体)和纯氮中进行。结构钢和工具钢的高温渗氮这类渗氮属于在温度超过600℃用氮饱 Material nitriding is generally carried out at 500 ~ 580 ℃ (low temperature nitriding). In recent years, pearlite steels, ferritic-martensitic steels, ferrochromic steels and austenitic steels, nickel alloys and refractory metals (Ti, Mo, Nb, V, Gr, etc.) (600 to 1200 ° C). Nitriding is carried out in a mixture of ammonia, ammonia and carbon-containing gas (endothermic gas) and pure nitrogen. Nitriding of structural steels and tool steels This type of nitriding belongs to saturation with nitrogen at temperatures in excess of 600 ° C
