以钼酸铵和硫化铵为原料,通过化学沉淀法制备了前驱体三硫化钼,再经过氢气份脱硫制备了纳米二硫化钼固体润滑剂微粒,利用透射电子显微镜(TEM)、激光粒度分析仪和X射线衍射(XRD)对粉体粒子形貌、大小和相结构进行了分析。结果表明:制备纳米二硫化钼微粒的条件为pH值为6.0,煅烧温度为500℃,保温时间为30min,所得微粒粒径为20-40 nm左右的球形颗粒。
Ammonium molybdate and ammonium sulphide were used as raw materials to prepare the molybdenum disulfide solid lubricant particles by chemical precipitation, and then the particles were desulfurized by hydrogen gas. Transmission electron microscopy (TEM), laser particle size analyzer And X-ray diffraction (XRD) on the particle morphology, size and phase structure were analyzed. The results show that the preparation conditions of the nano-MoS2 particles are pH value of 6.0, calcination temperature of 500 ℃, holding time of 30min, the size of the obtained particles is about 20-40 nm spherical particles.
