对渗硼工艺形成的硼化物层脆性进行了分析 ,认为其剥落脆性是影响硼化物层脆性的主要因素。探讨了 Cr及 RE元素对降低硼化物脆性的机理 ,同时用 EET理论对含 Cr硼化物的价电子结构进行了研究
The brittleness of the boride layer formed by the boronization process is analyzed. It is considered that the brittleness of the boride layer is the main factor that affects the brittleness of the boride layer. The mechanism of reducing the brittleness of the boride by Cr and RE elements was discussed. At the same time, the valence electron structure of the boride containing Cr was studied by EET theory
