Thus, a time interval between the first sintering process and the second sintering process can be reduced, and no more nitrogen is wasted in transition from the first sintering process to the second sintering process.

Abstract: A method for improving lubricating performance of lubricating oils is provided and includes: adding copper phosphate with a porous structure into a base oil, a mass percent of the copper phosphate with the porous structure to the base oil is 0.0001% ˜50%, the porous structure is one of a foam porous structure and a porous nanoflower structure. The copper phosphate with the porous structure is obtained by adding a divalent copper salt solution into an alkaline disodium hydrogen phosphate solution or alkaline phosphoric acid buffer solution and then separating a precipitate. When a ratio of a concentration of a divalent copper ion to that of a phosphate ion is 1:0.1 to 400, the porous structure is porous foam or nanoflower. The porous structure can be well dispersed in the lubricating oil for 1 hour. After adding the lubricating oil, excellent friction reduction and anti-wear is achieved.

Abstract: Disclosed is a friction-reducing and anti-wear composite material for a wading kinematic pair and a method of preparing the same. The friction-reducing and anti-wear composite material is prepared from carbon fiber (CF) among inorganic fillers, polyimide (PI) and polyether ether ketone (PEEK). These three materials are wet-mixed, dried and placed in a mold followed by curing by a heat press. The cured product is cooled and demolded to obtain the CF/PI/PEEK friction-reducing and anti-wear composite material for a wading kinematic pair. Tribological properties of the PEEK material are enhanced due to synergistic effect arising from hybrid organic-inorganic filling. The friction-reducing and anti-wear composite material provided in the invention has significantly reduced friction coefficient and wear volume loss under the seawater environment.
