本文利用在离子氮化炉阴极上挂海锦钛的方法研究了钛对离子氮化层的影响。试验结果表明,钛不仅能提高氮化层硬度、增加氮化层深度,并且对氮化层的相组成及表层的合金元素分布都有影响。一、试验用钢及试验方法试验用35CrMo和40Cr两种结构钢,经调质后加工成试样,试样热处理工艺如表1。 In this paper, the use of the sea in the ion nitriding furnace Hangjin titanium method of titanium on the ion nitriding layer. The experimental results show that titanium can not only improve the hardness of the nitride layer and the depth of the nitride layer, but also affect the phase composition of the nitride layer and the alloying element distribution of the surface layer. First, the test steel and test methods Test 35CrMo and 40Cr two structural steel, the quenched and tempered and processed into a sample, the sample heat treatment process shown in Table 1.
