Abstract

The invention relates to a MoS2-group self-lubricating wear-resistant corrosion-resistant alloy and a preparation method thereof. The MoS2-group self-lubricating wear-resistant corrosion-resistant alloy comprises the following components by weight percent; 0.3-0.4% of C, 0.03-0.08% of N, 2-5% of Cu, 8-16% of Ni, 2-25% of MoS and the balance of aluminum base. The MoS2-group self-lubricating wear-resistant corrosion-resistant alloy has favorable self-lubricating properties of low friction and wear resistance, has high mechanical strength and corrosion resistance, is suitable for producing dry friction parts such as bearing retainers, shaft sleeves, sliding plates, sealing elements and control valves operating in a self-lubricating, dry-friction and helium-atmosphere environment and at a high temperature in the industrial production field of metallurgy, energy and nuclear power, and has special application requirements. By the preparation method, alloy can be prepared conveniently and rapidly, and the preparation method has the characteristics that the burning loss of alloy components is small and the components can be easily controlled.

Description

technical field [0001] The invention belongs to the field of alloy technology and relates to a MoS 2 Based self-lubricating wear-resistant and anti-corrosion alloy, the present invention also relates to the MoS 2 A method for preparing a self-lubricating wear-resistant and corrosion-resistant alloy. Background technique [0002] With the development of social economy, modern industrial manufacturing, nuclear power and military fields have put forward more and more urgent needs for high-temperature non-lubricated special environments. Engineering materials used as friction parts at high temperatures must work in harsh or even dry friction environments and conditions. High temperature oxidation, high friction and severe wear can cause engineering materials to fail quickly. Since oil or other materials are not allowed to lubricate, the research shows that from the perspective of the mechanical and tribological comprehensive properties of the material, the available ready-mad...
