Synthesis method and apparatus for solid lubricants by solid-phase reaction in high pressure atmosphere

摘要

The present invention relates to a method for synthesizing and synthesizing a solid lubricant having a lubricating effect even at a high temperature of 500 ° C. or higher and a vacuum atmosphere of 10 ⁻⁵ torr or less. Particularly, a constant molar ratio of a Group 4B or 5B transition metal powder and a Group 6A element powder a raw material powder mixture to react with stirring in the high-pressure atmosphere relates to WS _2, MoS _2, WSe _2, etc. dichal chalcogenides (dichalcogenide) type method for synthesizing a solid lubricant powder with the device used to this.;Tungsten (W), molybdenum (Mo), niobium (Nb), thallium (Ta) are Group 4B or Group 5B transition metals, and sulfur (S), selenium (Se), tellurium (Te), etc. : The raw material powder uniformly mixed at a molar ratio of 2.2 to 3.0 was introduced into the reaction drum 1, and the inside of the reaction drum 1 was maintained at a constant high pressure by repeating operation of the open / close valve 3 and the motor 6 While stirring the reaction drum (1) at about 800 ~ 1000 ℃ heat treatment for 2 hours or less to synthesize a solid lubricant.;Method of heat treating existing raw material powder in vacuum vessel, flowing H ₂ S gas to transition metal oxide and reacting, converting transition metal oxide into water-soluble salt and reacting with salts containing group 6A In contrast, by simplifying the process, production facilities and production costs can be reduced and mass production is possible.
