摘要
对比分析了采用烧结破碎和团聚烧结工艺制备的两种WC-10Co-4Cr粉末的物理性能和物相组成。采用超音速火焰喷涂技术对两种粉末进行了涂层制备,并对两种涂层的性能进行对比评价,结果表明:团聚烧结粉末制备涂层的硬度、孔隙率和抗冲蚀磨损性能均优于烧结破碎粉末制备涂层,但其结合强度略低于烧结破碎粉末制备涂层。
The physical properties and phase composition of two different WC-IOCo-4Cr powder prepared by kinds of sintering broken and agglomeration sintering processes were analyzed comparatively. Coatings were prepared by HVOF using the two powder and the properties of the two kinds of coatings were also evaluated comparatively. The results revealed that the hardness, porosity and erosion wear resistance of coating prepared from agglomeration sintering powder were superior to the coating from sintering broken powder. Nevertheless, the bonding strength of the coating from agglomeration sintering powder was appreciably lower than that from sintering broken powder.
