    摘要
  • 摘要: 针对家用3Cr13不锈钢厨刀硬度低、耐磨性差、使用寿命短等问题，采用激光熔覆技术对其进行处理，改善厨刀的性能.研究了激光熔覆层的显微硬度及显微组织.结果表明，采用经优化的激光熔覆处理工艺，可以获得无气孔、裂纹和夹杂等缺陷的熔覆层，熔覆层与基体结合良好；熔覆层的显微硬度在7~12 GPa之间波动，平均显微硬度约为9 GPa，是基体的2.3倍，大大提高了刀刃的硬度；熔覆层中含有大量未熔的硬质颗粒WC，并镶嵌到相对较软的304L基体中，这种结构对WC颗粒起到韧化缓冲作用，保证刀具使用过程中WC颗粒不易脱落，从而可提高刀具的使用性能.
    Abstract: For the problems such as low hardness, poor wear resistance and short service life, the laser cladding technology was used to improve the performance of 3Cr13 stainless steel kitchen knife. The microstructure and microhardness of the laser cladding layer were studied. The results show that the laser cladding layer without porosity, crack and inclusions can be obtained with the optimized laser cladding process, which is well bonded with the substrate. The microhardness of the laser cladding layer fluctuates between 7.0~12.0 GPa. The average microhardness is about 9.0 GPa, which is about 2.3 times of that of the substrate. The hardness of the blade is greatly increased. The laser cladding layer contains a lot of hard WC particles, which are not melted. The unmelted WC particles embedd into relatively soft 304L matrix. This structure has a toughening buffer effect on the WC particles. Therefore it ensures that the WC particle is not easy to fall off when cutting tools is used. Thus the work ability of the cutting tools can be improved.
