研究了两段固体碳氮硼三元共渗。通过试验选出了渗剂。用该渗剂对工业纯铁、15钢、45钢等进行570℃×3h—900℃×5～6h共渗处理后,得到由硼化物层和碳氮层组成的共渗层。渗层组织及相结构分析表明:共渗层中有一定数量的ε,γ′和Ee_3(C,B)粒子相,其中ε相最多且以棒条状或小球状存在。还对共渗过程的有关化学反应进行了热力学分析。对渗层的脆性、耐磨性与渗硼进行了对比试验。
Two stages of solid carbonitride boron ternary permeation were studied. Through the test selected osmotic agent. The industrial pure iron, 15 steel and 45 steel are infiltrated with the penetration agent at 570 ° C × 3h-900 ° C for 5 to 6 hours to obtain a co-diffusion layer composed of a boride layer and a carbonitride layer. The analysis of the microstructure and phase structure of the infiltrated layer shows that a certain amount of ε, γ ’and Ee_3 (C, B) phase are present in the co-infiltrated layer, of which the ε phase is the most and exists in the form of rod or pellet. The chemical reactions of the infiltration process were also thermodynamically analyzed. The embrittlement of brittleness, wear resistance and boronizing carried out a comparative test.
