Abstract

The invention discloses a design and preparation method of a multi-layer composite structural NiTiCrBNb-based self-lubricating material for a slide plate. The self-lubricating material uses a NiTiCrBNb-based alloy, a curing agent, an anti-friction agent, an anti-wear agent, and a buffer material as main components, and the multi-layer composite structural NiTiCrBNb-based self-lubricating materialfor the slide plate is prepared through the processes of design of each layer material, calculation, preparation, vibration mixing, hot-press forming, spark plasma sintering and subsequent machining.The multi-layer structural material for the slide plate is formed by overlaying and compounding of four layers of sheets, and plays a role of lubrication, support, transition and connection in the friction process; compared with a traditional graphite-containing metal-based block self-lubricating composite material, the multi-layer structural composite material provided by the invention has a significantly-improved material utilization rate and reduced material costs; and at the same time, the multi-layer structural slide plate has wide temperature range tribological characteristics, so that the slide plate can still maintain a small friction coefficient and a low wear rate under high and low temperature service conditions.
