摘要 无水碳酸钠和硝酸钙为原料,用水热法制备了碳酸钙粉体.通过SEM、XRD、FT-IR对CaCO3粉体的形貌和结构进行了表征.将不同条件下制备的CaCO3粉体用油酸进行修饰后,在四球摩擦磨损试验机上考察其作为润滑油添加剂的摩擦学性能. Calcium carbonates were hydrothermally synthesized using sodium carbonate and calcium nitrate as raw materials.The structure and morphologies of calcium carbonate in different conditions were investigated by XRD,FT-IR and SEM.The tribological properties of the oleic acid modified calcium carbonates as lubricant additives were evaluated on four-ball tester.
