摘要
以MgO和SiO2为原料,采用水热法合成了粒径为1～3μm的蛇纹石粉体。利用X射线衍射仪、扫描电子显微镜表征了粉体的物相组成和微观形貌。设计阶梯加载和提速试验,利用MMW-1A型万能摩擦磨损试验机考察了载荷和转速对蛇纹石粉体自修复性能的影响。结果表明:载荷和转速对蛇纹石粉体自修复性能的发挥影响显著。含蛇纹石粉体油品为润滑介质,载荷为20 kg、转速为300 r/min时试样实时磨损量最小;与46#机械油润滑相比,此时磨损表面光滑平整,被有效修复。
Using MgO and SiO2 as raw materials, serpentine powders were synthesized through hydrothermal reaction and the particles had a mean diameter of 1-3μm. The phase composition and morphology of synthesized powders were characterized by X-ray diffraction （XRD） and scanning electron microscopy （SEM）. Ladder-shaped adding load and revolving speed experiments were designed to investigate the influence of load and revolving speed on the self-repairing property of serpentine powders by using MMW- 1A universal friction and wear tester. Results showed that load and revolving speed had great influence on the self-repairing property of serpentine powders. When lubricant was the oil with serpentine powders as additive, the real-time weight loss was minimum at the load 20 kg and revolving speed 300 r/min, the worn surface became smoother and had been repaired effectively compared with 46th mechanical oil as lubricant.
