摘要

通过激光熔覆在304不锈钢表面制备了Stellite 12涂层, 研究了添加不同质量分数的Ti/B4C对Stellite 12涂层组织及性能的影响, 分析了涂层组织的生长, 测试了涂层的显微硬度及耐磨性能。研究结果表明, Stellite 12涂层主要由面心立方的γ-Co与Cr7C3相组成。随着Ti/B4C的添加, 涂层原位合成了TiC亚微米颗粒相。残存的B4C作为异质形核点, 形成了亚微米结构TiC/B4C强化相, 且颗粒尺寸逐渐减小。TiC/B4C颗粒对涂层晶粒有细化作用。涂层显微硬度随着添加Ti/B4C的质量分数的增加逐渐增大,最高为624 HV。涂层耐磨性能随添加的Ti/B4C质量分数的增加逐渐增强。

Abstract

The Stellite 12 coating is synthetized on the 304 stainless steel surface by laser cladding, and the effect of the addition of Ti/B4C with different contents on the microstructure and properties of the Stellite 12 coating is discussed. The microstructural growth of the coating is analyzed, and the microhardness and wear resistance of the coating are also tested. The research results show that the Stellite 12 coating is mainly composed of face-centered cube γ-Co and Cr7C3 phases. The in-situ TiC sub-micron particle phase is synthesized with the addition of Ti/B4C. The remaining B4C acts as a heterogeneous nucleation point, and thus a TiC/B4C strengthening phase with sub-micron structure is formed and the particle size gradually decreases. The TiC/B4C particles have an obvious grain refinement effect on the coating. The micro-hardness of the coating gradually increases with the addition of Ti/B4C with the maximum value of 624 HV. In addition, the wear resistance of the coating gradually increases with the addition of Ti/B4C.
