Embodiment

[0036] First, remove the grease on the cronidur30 bearing steel material with a metal degreasing solvent, so that there is no grease on the surface, then put the cronidur30 bearing steel material to be treated into non-polluting tetrachlorethylene for 30 minutes, take it out, and then use rice paper to absorb it After the solvent remains, wipe the surface of the sample with absorbent cotton, and finally wipe it with clean silk; then soak and clean the cronidur30 bearing steel material with metal derusting solvent for 15 minutes to remove the rust spots on the surface of the material; then put it in acetone and ultrasonically clean it After 30 minutes, take it out and dry it with a clean silk cloth; then soak and clean the cronidur30 bearing steel material with a metal cleaning agent with the function of removing organic matter for 15 minutes, so that no organic matter remains on the surface of the metal sample, and finally put the treated cronidur30 bearing steel material Put t...

Abstract

The invention discloses a treatment method for cronidur30 bearing steel, a reinforced cronidur30 bearing steel and a bearing. The method includes: employing metal high-energy ions and large beam current gas ions to perform alternate bombardment on cronidur30 bearing steel so as to inject metal ions and gas ions to the surface of the cronidur30 bearing steel, firstly injecting at least two different metal ions to the surface of the cronidur30 bearing steel, and finally injecting gas ions to the surface of the cronidur30 bearing steel. The method provided by the invention can solve the problem of material performance reduction caused by nitrogen loss on the surface of the cronidur30 bearing steel, and also can significantly improve the antiwear and friction reduction properties of the cronidur30 bearing steel.

Description

technical field [0001] The invention belongs to the field of surface strengthening treatment of metal materials. Specifically, the invention relates to a method for treating cronidur30 bearing steel, strengthening the cronidur30 bearing steel and bearings. Background technique [0002] Cronidur30, M50NiL and M50 bearing steel materials are high-temperature bearing materials widely used in aviation bearings at the present stage. The nitrogen of cronidur30 material replaces the carbon element in part of the bearing steel, avoiding the formation of larger carbides or carbides by more carbon The network compound has better corrosion resistance and high temperature resistance, and has a wider industry promotion value in the bearing industry. Bearings made of cronidur30 material usually need to maintain high speed under heavy load, and the working environment is relatively harsh. In this case, wear failure is very easy to occur. Therefore, higher requirements are put forward for t...
