用高温快速加热对低淬透性材料进行表面淬火,可以代替高频表面淬火。这是挖掘传统工艺的潜力,解决部分汽车拖拉机修理厂无高频设备困难的好办法。凡是低淬透性材料零件,小批量生产,均可使用。 一、方法 以解放CA—10B汽车前钢板销为例。(图1),材料45号钢,要求硬化层深度1～3.5毫米,硬度HRC58～63。 Rapid heating with high temperature on the low hardenability of materials for surface hardening, can replace high-frequency surface hardening. This is a good way to tap the potential of traditional crafts and solve the hardship of some car tractor repair shops without high-frequency equipment. All low-hardenability materials parts, small batch production, can be used. First, the method to the liberation of CA-10B automobile front pin as an example. (Figure 1), material 45 steel, hardened layer depth of 1 to 3.5 mm, hardness HRC58 ~ 63.
