摘要
针对旋耕刀降阻降耗、减粘脱附和耐磨延寿等性能需求,提出一种金刚石钎涂耐磨涂层制备方法,并与电弧熔覆耐磨焊丝涂层、等离子堆焊WC涂层进行对比研究。结果表明,金刚石钎涂层中金刚石分布均匀且与钎料结合良好,充分发挥了承载相作用,耐磨性明显优于电弧熔覆涂层和等离子堆焊涂层,磨损失重仅为0.0562 g,且田间试验结果表明,金刚石钎涂旋耕刀可持续耕作2500亩以上,为电弧熔覆旋耕刀和等离子堆焊旋耕刀使用寿命的4.12倍和3.13倍;田间试验结果表明,其旋耕作业扭矩为584.66 N·m,为电弧熔覆旋耕刀和等离子堆焊旋耕刀旋耕扭矩的79.1%和89.9%,其土壤粘附率为0.8%,为电弧熔覆旋耕刀和等离子堆焊旋耕刀土壤粘附率的53.3%和70.2%,表现出优异的降阻减粘性能。
In response to the performance requirements of reducing resistance and consumption,reducing adhesion and detachment,and improving wear resistance and durability of rotary tiller blades,a method for preparing diamond-coated wearresistant coatings is proposed.The method is compared with arc-sprayed wear-resistant welding wire coatings and plasmasprayed WC coatings.The results show that the diamond-coated wear-resistant coating has a uniform distribution of diamonds and good bonding with the solder,fully exerting the role of the load-bearing phase.It has significantly better wear resistance than the arc-sprayed and plasma-sprayed coatings,with a weight loss of only 0.0562 g.Field tests also show that the diamond-coated rotary tiller can sustainably cultivate an area of over 2500 acres,which is 4.12 times and 3.13 times longer than the lifespan of the arc-sprayed and plasma-sprayed rotary tillers,respectively.Furthermore,the torque during rotary tillage is 584.66 N·m,which is 79.1%and 89.9%of the torque of the arc-sprayed and plasma-sprayed rotary tillers,respectively.The soil adhesion rate is 0.8%,which is 53.3%and 70.2%of the soil adhesion rate of the arc-sprayed and plasmasprayed rotary tillers,respectively,demonstrating outstanding resistance reduction and anti-adhesion performance.
