渗硼一种重要的表面处理方法,可以为材料提供极高的硬度、耐磨性等。本文研究了不同温度下对WC/钢复合材料表面进行渗硼处理。结果表明,随着温度的增加,材料的强度不断减小,然后断裂韧性钨明显变化。此外,渗硼层主要是解理断裂,基体主要是鱼骨状碳化物脆性断裂和钢的韧性断裂。 Boronizing an important surface treatment methods, can provide materials with high hardness, wear resistance and so on. In this paper, the surface of WC / steel composites were infiltrated at different temperatures. The results show that with the increase of temperature, the strength of the material decreases continuously, and then the fracture toughness of tungsten changes obviously. In addition, boronizing layer is mainly cleavage fracture, the matrix is ​​mainly brittle fracture of fish bone carbide and ductile fracture of steel.
