采用固体粉末法 ,对 2 0钢和 45钢进行渗硼处理 .加热到 560℃～ 70 0℃ ,保温 6h～ 1 0 h,可以得到深度为 1 3μ～ 65μ的渗硼层 ,试验结果表明 ,在相变点以下温度保温一定时间 ,可以达到渗硼的目的 .渗硼层深度随保温温度提高及保温时间增加而加深
Boronizing treatment was carried out on 20 steel and 45 steel by solid powder method.The boronizing layer with the depth of 13μ ~ 65μ can be obtained by heating to 560 ℃ ~ 70 ℃ and holding for 6h ~ In the phase transition point below the temperature insulation for a certain period of time, can achieve the purpose of boronizing boron layer depth with the insulation temperature and insulation time increases and deepen
