Abstract

The invention discloses a tribological design and preparation method of an FeNiAlNb-based pin shaft multilayer composite structure material. A FeNiAlNb matrix, an antifriction agent, an anti-wear agent and a reinforcing agent are adopted as the components, a multi-element tabular crystal is prepared, by means of each layer material component design and computation, vibration mixing, hot press molding, multi-layer structure compounding and subsequent machining procedures, the FeNiAlNb-based pin shaft multilayer composite structure material can be prepared. Through reasonable design and optimalproportioning of the matrix alloy, the antifriction agent, the anti-wear agent and the reinforcing agent on a friction film, a bearing transition layer and a matrix bearing layer, the material utilization rate is improved, the production cost is reduced, and the FeNiAlNb-based pin shaft multilayer composite structure material can meet the friction and wear properties under high-low temperature andhigh-load working conditions while having excellent thermal stability and mechanical properties, and also significantly enhances the use precision and service life of the pin shaft on the premise ofobviously improving the connection strength and bearing capacity of the pin shaft.

Description

technical field [0001] The invention belongs to the technical research field of anti-friction and wear-resistant materials such as pin shafts, shaft sleeves and sleeves, and specifically relates to a FeNiAlNb-based pin shaft multilayer composite structure material and its preparation method, which belongs to the multilayer self-lubricating composite material in extreme service environments Structural design and preparation technology field. Background technique [0002] Due to the rapid development of modern high-end mechanical assembly technology, large suspended objects require the connecting pin to have a large bearing capacity, high specific strength and good thermodynamic properties, etc. However, it is easy to form under the combined conditions of high temperature, heavy load and high speed. High friction and high wear. Large friction promotes high frictional resistance, generates large frictional heat, and leads to a large amount of energy consumption under the condi...
