钛及其合金的热处理提到刃具材料,我们首先会想到它能不能像碳钢那样通过淬火等手段来提高其硬度。一般市售的刃具制品,碳素工具钢的HRC大于61,不锈钢的HRC也大于58。本文作者为探讨提高钛材硬度的方法,就其氮化处理时表层TiN的形成和β型合金所特有的时效对提高钛材硬度的作用进行了实验。氮化处理氮化处理实验使用的是小型真空电炉。抽空减压后升温至所需温度,注入氮气至所需压力,再保温至所需时间。具体设定条件如表1所示。处理后的评定方法,
Titanium and its alloy heat treatment referred to cutting tool material, we will first think of it as carbon steel can not quench the other means to increase its hardness. Generally available cutting tool products, carbon tool steel HRC greater than 61, HRC stainless steel is greater than 58. In order to explore the method to improve the hardness of titanium, the author has carried out the experiments on the formation of surface TiN during nitriding and the effect of the aging of β-type alloy on the hardness of titanium. Nitriding Nitriding experiments using a small vacuum furnace. After evacuating, the temperature is raised to the required temperature, nitrogen is injected to the required pressure, and then the temperature is kept to the desired time. Specific conditions set in Table 1 below. After the assessment method,
