超音速火焰喷涂WC-17Co涂层微观结构与性能研究OA北大核心CSCDCSTPCD
Microstructure and Performance of WC-17Co Coatings Fabricated by High Velocity Oxy-fuel Spraying
采用超音速火焰喷涂技术喷涂了两种不同WC颗粒尺寸的WC-17Co粉末.对制备的两种涂层的硬度、孔隙率、断裂韧性、结合强度和电化学腐蚀行为进行了测试.结果表明:具有亚微米结构WC颗粒的粉末制备的涂层,在硬度、孔隙率、断裂韧性方面具有一定优势,而含有大颗粒WC相的粉末制备的涂层在结合强度、腐蚀行为方面优势明显,这说明WC颗粒尺寸对涂层性能有显著影响.
Different structural WC-17Co coatings were deposited by high velocity oxy-fuel (HVOF) spraying. The properties of the two coatings were tested, and the effect of WC size on the performance of the coatings was investigated. The results indicated that G coating, which had submicron WC particle, showed more advantages in hardness, porosity,and fracture toughness,while H coating with bigger WC particle had excellent performance in adhesive strength and corrosion…查看全部>>
