除不含强烈形成碳化物元素的钢种渗碳和渗锌等少数情况下,可采用高活性介质外,适当降低介质活性,是提高渗层质量、降低成本,甚至能在提高质量的同时缩短处理时间的强化方法。此法具有准普遍性(可以广泛采用,但不能用于一切工艺),既可节约能源,提高价值工程商数,又简便易行,成效卓著。笔者认为适当降低介质活性是表面合金化的一种强化规律,对此种规律的强化机理进行了初步研究。
In addition to carburizing and infiltrating zinc, which do not contain strongly carbides, the medium can be used to reduce the activity of the medium properly in order to improve the quality of the layer and reduce the cost, and even shorten the quality while improving the quality Processing methods of strengthening time. This method is a quasi-universal (can be widely used, but can not be used in all processes), can save energy, improve the value of the project quotient, but also simple and effective. I believe that the appropriate reduction of medium activity is the surface alloying of a strengthening of the law of strengthening the mechanism of a preliminary study.
