摘要
Abstract
The optimal technological parameters and the prescription of the Paste-boronizing for steel is obtained by orthogonal experimental design. The influence of different heat treatment processes after paste-boronizing on the structure and the performance of steel 45 and T10 is investigated. The result shows that the thickness of the boronized-layer is higher than 110u,m and the micro-hardness is higher than 1130HV for steel 45, and the thickness of the boronized-layer is higher than 60p.m and the micro-hardness is higher than 1360HV for steel T10. There is no effect on the micro-hardness and the thickness of boronized-layer by the heat treatment, but it can . Affect the structure and performance of substrate significantly. The tempered-martensite of the substrate can be obtained through the process of quenching and low tempreture tempering after paste-boronizing, the micro-hardness of the substrate was enhanced, then the difference of the hardness between substrate and boronized-layer was reduced and the sustaining ability of the substrate for boronized-layer was improved.关键词
