摘要

以FeB、Mo等粉末为主要原材料

采用先烧结陶瓷后铸造复合的方式制备金属陶瓷/钢基覆层材料

并对覆层材料的界面组织、覆层硬度、覆层耐磨性进行了研究。结果表明

金属陶瓷/钢基覆层材料由表及里分别为金属陶瓷表层、过渡区及钢基体

过渡区由3层过渡层构成梯度组织结构。金属陶瓷与钢基体形成冶金结合

界面组织致密无缺陷。金属陶瓷覆层的硬度（HV）为1 098

远高于45钢

其耐磨性与硬质合金YG8相当。

Abstract

The cermet/steel cladding coating was prepared by sintering and casting compound method with FeB

Mo and other powders as the main raw materials.The interface structure

composition

hardness

wear resistance and corrosion resistance of the cladding coating were investigated by SEM

EDS and tensile testing.The results indicate that the cermet/steel cladding materials consist of cermet layer

transition zone and steel matrix from the surface to the center

and the transition zone is composed of three layer transition layer

presenting gradient structure.The cermet is presented metallurgical bonding with the steel matrix with the absence of defects in interfacial structure.In addition

the hardness of the metal ceramic layer is 1 098 HV

which is much higher than that of 45 steel matrix.The performance test of the cladding material shows that the cermet/steel cladding material has similar wear resistance with YG8 cemented carbide.
