我厂用来固体渗碳的渗碳剂成分是:木炭90%,碳酸钠10%。工件材料是20号钢,在900～930℃渗碳,保温4小时,渗碳的深度可以达1公厘。工件表面的含碳量,根据火花鉴别,可以达到1.0%左右。最近我们在进行固体渗碳时,先分别把木炭和碳酸钠烘干,去除里面的水分后再混合起来。碳酸钠在烘烤时,先从糊 I plant for solid carburizing carburizing ingredients are: 90% charcoal, sodium carbonate 10%. The workpiece material is 20 steel, carburizing at 900 ~ 930 ℃, heat 4 hours, the depth of carburizing up to 1 mm. The carbon content of the workpiece surface, according to the spark identification, can reach about 1.0%. Recently, we conducted solid carburizing, first charcoal and sodium carbonate were dried, remove the moisture inside and then mixed together. Sodium carbonate in the baking, the first from the paste
