Embodiment Construction

[0013] A self-lubricating cermet bearing with high bending strength, made of the following raw materials in parts by weight (kg): iron citrate 2.3, basic nickel carbonate 3.1, cuprous iodide 1.1, water 25, ammonia water, TiH 2 2.9, TiC5, Mo 2 C3, WC3, LaB 6 0.9, germanium dioxide 0.6, nano boron fiber 0.6, lubricant 0.7, C1, W8.6, Mo6.1, V3.1, Fe65.

[0014] The preparation method of the self-lubricating cermet bearing with high bending strength comprises the following steps:

[0015] (1) Add ferric citrate and cuprous iodide into water in a nitrogen atmosphere, heat to 60°C, stir at 90 rpm for 1.5 hours, add TiC, Mo 2 C, WC, LaB 6 , germanium dioxide, and nano-boron fiber, stirred for 1 hour, then added basic nickel carbonate and stirred for 3 hours, adjusted the pH value to 6 with ammonia water, heated to 90°C and kept stirring for 2 hours to obtain a gel;

[0016] (2) Heating the gel to 150°C and maintaining the temperature until no smoke is produced, then stopping the ...

Abstract

The invention discloses a self-lubricating metal ceramic bearing with high bending resisting strength. The bearing is prepared from raw materials including, by weight, 2.3-2.4 parts of ferric citrate, 3.1-3.5 parts of basic nickel carbonate, 1.1-1.3 parts of cuprous iodide, 25-30 parts of water, a proper amount of ammonium hydroxide, 2.9-3 parts of TiH2, 5-5.6 parts of TiC, 3-4 parts of Mo2C, 3-4 parts of WC, 0.9-1.1 parts of LaB6, 0.6-0.8 part of germanium dioxide, 0.6-0.8 part of nanometer boron fibers, 0.7-0.9 part of a lubricating agent, 1-1.1 parts of C, 8.6-9 parts of W, 6.1-6.3 parts of Mo, 3.1-3.3 parts of V and 65-66 parts of Fe. By means of the Mo2C, the WC, the LaB6, the germanium dioxide and the nanometer boron fibers, the thermal resistance and bending resisting strength of the bearing are improved, the bearing has the characteristics of high hardness, high strength and high tenacity, and cracking is prevented.

Description

technical field [0001] The invention relates to the technical field of cermet bearings, in particular to a self-lubricating cermet bearing with high bending strength and a preparation method thereof. Background technique [0002] The development of modern science and technology has higher and higher requirements on the friction, wear and lubrication performance of materials under high temperature conditions. The research and development of self-lubricating composite materials has become an important research hotspot in the field of tribology. Metal or ceramic-based self-lubricating materials are composite materials formed by adding solid lubricants into metal or ceramic matrix as components, and their tribological properties depend on the precipitation and dispersion distribution of solid lubricant contained in the matrix during the friction process. However, there are few solid lubricants that can withstand high sintering temperature without losing lubricating properties, ...
