Silver is a good lubricant at moderate temperature while oxides of molybdenum are effective at high temperature. In order to improve surface wear resistance and realize self-lubrication over a wide temperature range, molybdenizing and nitriding duplex-treatments were performed on the silver-containing nickel-base alloy by utilizing a double glow plasma alloying technology. The tribological properties...
The molybdenum disulfide and metal silver are commonly used solid lubricants at the temperature below 500°C, while the rare earth compound is useful at high temperature but ineffective at room temperature. These solid lubricants are limited in special temperature ranges. When they are combined in the nickel-base alloy, a self-lubrication over a wide temperature range is reached. The nickel-base composites...
