本文对模具钢固体粉末渗锰工艺进行了探讨,并分析了不同温度、不同时间及不同成分对渗层深度、相结构、硬度、耐磨性、热疲劳及脆性的影响。试验表明,模具钢渗锰层具有较小的脆性,可有效地提高硬度,耐磨性和使用寿命,特别是可改善热作模具的热疲劳性能。 In this paper, the process of solid manganese powder penetrating manganese was discussed. The effects of different temperature, time and composition on the depth, phase structure, hardness, wear resistance, thermal fatigue and brittleness were analyzed. The test shows that the manganese steel layer of the mold steel has less brittleness, which can effectively improve the hardness, the wear resistance and the service life, and especially can improve the thermal fatigue performance of the hot die.
