摘要:

采用原位反应真空液相烧结技术,在Q235钢基体表面制备三元硼化物硬质合金覆层,使钢基体表面获得耐磨抗蚀、界面结合强度高的覆层材料。利用扫描电镜和能谱分析对三元硼化物硬质合金和钢基体的界面微观结构和界面区元素分布进行了分析,发现硬质合金覆层和钢基体之间形成了一个具有一定厚度的过渡层,合金元素浓度没有发生突变,两相之间形成了良好的冶金结合。研究了覆层材料的显微硬度、抗弯强度与耐磨性能,结果表明:在1200℃烧结,覆层的Vickers硬度达到12MPa,弯曲强度在试样受到拉伸应力与压缩应力时分别达到86.74MPa,1168.21MPa,耐磨性与Q235钢相比有了较大提高。

A ternary boride hard alloy was prepared on Q235 steel substrate surface to form a new type of cladding material with ex-cellent wear and corrosion resistance by in situ reaction and liquid phase sintering in a vacuum furnace. The microstructure and ele-ment distribution of the cladding-substrate interface area were studied using a scanning electron microscope and energy dispersion spectrometer. An interim layer with a certain width between the hard alloy cladding and steel substrate with good metallurgy coales-cence between the two phases is formed, where the distribution of elements continuously changes. The microhardness, bending strength and wear resistance of the cladding material were studied. The experimental results indicate that the Vickers hardness of the cladding material is 12 MPa; the bending strength is about 86.74 MPa in tensile stress and 1 168.21 MPa in compress stress, when it was sintered at 1 200 ℃ , and the wear resistance of the cladding material is more excellent than Q235 steel.
