中文摘要：采用激光熔覆技术在Q235钢表面制备了不同TiC和Nb含量的Fe60基复合涂层,并通过原位反应形成Nb C强化相,研究了Nb的添加对熔覆层微观组织演化和力学性能的影响。结果表明,原位合成相由TiC、Nb2C和NbC等强化相组成。加入Nb后,Nb与TiC反应生成NbC,提高了涂层中颗粒相分布的均匀性。相比Fe60涂层,添加Nb的涂层显微硬度降低,但通过改善显微组织,其磨损率降低。

外文摘要：Fe60-based composite coatings with different TiC and Nb contents were prepared on the surface of Q235 steel by laser cladding technology,and NbC strengthened phases were formed by in-situ reaction to investigate the effects of the addition of Nb on the microstructure evolution and mechanical properties of the cladding layers.The results show that the in-situ synthesized phase consists of strengthening phases such as TiC,Nb2C and NbC.After adding Nb,Nb reacts with TiC to form NbC,which improves the particle distribution uniformity of the coating.Compared with that of the Fe60 coating,the microhardness of the coatings with Nb addition decreases,but the wear rate is reduced through improving the microstructure.
