| 摘 要： | 研究了氩弧重熔对Q235钢B-C-N共渗层的组织结构、水冲蚀磨损及海水介质腐蚀磨损性能的影响。XRD分析显示,共渗层由FeB、Fe2B、Fe3B、Fe2N、Fe8N和Fe3C相组成,氩弧重熔层由Fe2B、Fe3N、Fe8N、Fe3C和Fe23(B,C)6相组成;共渗层显微硬度最高值为1198.4HV,重熔层最高硬度值为1192.8HV,但硬度梯度变化平缓;在水介质冲蚀及海水介质腐蚀磨损试验中,重熔层的耐磨性均优于共渗层。

| Abstract: | Effects of argon arc remelting on microstructure,erosive wear resistance to water and seawater of the B-C-N boride on Q235 iron were studied. The analysis result of XRD showed that the B-C-N boride was composed of FeB, Fe2B, Fe3B, Fe2N, Fe8N and Fe3C phase,while the argon arc remelting boride was composed of Fe2B,Fe3N,Fe8N,Fe3C and Fe23(B,C)6 phase.The highest microhardness value of the boride layer was 1198.4HV and the highest hardness value of after remelting layer was 1192.8HV,but the hardness gradient changed gently. In the tests of water erosion wear and seawater corrosion wear,the performance of remelting layer was better than the boride layer. |
