采用还原铁粉、碳化硼粉末、硼砂在基体金属材料Q235钢板上进行氩弧熔覆,并研究了6%、8%、10%、12%(质量分数)四种不同碳化硼含量对熔覆层组织和耐磨性的影响。结果表明,当碳化硼含量达到12%时熔覆层有新形成的Fe2B,随碳化硼含量的增加熔覆层硬度、抗磨粒磨损性能、抗黏着磨损性能、抗冲蚀磨损性能逐渐提高,当碳化硼含量达到12%时,硬度是基体的3.2倍,相对耐磨粒磨损、黏着磨损、冲蚀磨损性能都大幅度提高,分别是基体的5.4、3.7、4.3倍。 The reduction of iron powder, boron carbide powder and borax were performed on the Q235 steel with argon arc cladding. The effects of different boron carbide contents of 6%, 8%, 10% and 12% (mass fraction) Layer organization and wear resistance. The results show that when the content of boron carbide reaches 12%, there is newly formed Fe2B in the cladding layer. With the increase of boron carbide content, the hardness, wear resistance, wear resistance and erosion resistance of the cladding layer increase gradually. When the content of boron carbide reaches 12%, the hardness is 3.2 times that of the matrix, and the relative wear resistance, adhesion wear and erosion wear resistance are greatly increased, which are respectively 5.4, 3.7 and 4.3 times of the matrix.
