Abstract

The present invention discloses a nickel base self-lubricating material for water lubrication and its preparation process. The nickel base self-lubricating material contains Ni 80-95 wt%, Mo 0-5 wt%, Co 0-5 wt%, Ti 0-5 wt%, silicon carbide 5-10 wt%, and graphite 3-10 wt%. The self-lubricating material is prepared through powder metallurgical hot pressing and sintering process, has the advantages of high mechanical strength, excellent corrosion resistance and wear resistance in water, etc, and may be used in sealing gasket, bearing and other parts operating in water environment.

Description

technical field [0001] The invention relates to a nickel-based self-lubricating material for water lubrication and a preparation method thereof. Background technique [0002] The friction parts in the water environment often accelerate the wear of the parts due to the corrosion of various substances in the water, resulting in severe wear and failure. It is therefore necessary to develop materials with excellent wear and corrosion resistance in aqueous environments. Contents of the invention [0003] The purpose of the present invention is to provide a nickel-based self-lubricating material for water lubrication with excellent wear resistance and corrosion resistance and a preparation method thereof, the prepared nickel-based self-lubricating material for water lubrication Self-lubricating materials have excellent mechanical properties and tribological properties. [0004] Due to the corrosion resistance and oxidation resistance of nickel metal, the wear resistance of sil...
