▎ 摘　　要

NOVELTY - Nickel-molybdenum-boron-niobium based separator tribological design multilayer composite structure material, prepared by using nickel-molybdenum-boron-niobium matrix powder, graphene and multi-component composite materials as raw material to form self-lubricating multilayer composite structure material nickel-molybdenum-boron-niobium based separator from the bottom to top with different thicknesses, different components and different contents, is claimed. USE - Used as nickel-molybdenum-boron-niobium based separator tribological design multilayer composite structure material. ADVANTAGE - The material can meet the performance requirements of each part of the separator self-lubricating materials, can be used in extremely harsh environments with high temperature, strong pressure and high corrosion to achieve high-performance and reliable work, load-bearing capacity, pressure resistance, high temperature and corrosion resistance, especially the tribological performance can meet the required work requirements; improves the application range of separators in environments which are not easy to maintain, repair and lubricate has great potential value and broad application prospects.
