Surface metallization of solid lubricants and its effect on the mechanical properties of Fe-based bit matrix

  • 摘要: 自润滑孕镶金刚石钻头可为月球钻探难题提供新的技术方案,但固体润滑剂与钻头胎体之间湿润性较差,会导致胎体物理力学性能下降。研究固体润滑剂MoS2、WS2、CaF2自身材料特性差异及其对表面化学镀覆效果的影响,并探究了固体润滑剂镀覆前后对钻头胎体压入硬度和抗弯强度的影响。结果表明:化学镀可实现对上述3种固体润滑剂的表面镀镍处理,但镀覆效果存在一定差异;在相同体积浓度条件下,MoS2和WS2表面金属化能提升自润滑孕镶金刚石钻头胎体的力学性能,但CaF2的效果不明显。
