Abstract

The invention discloses a NiMoBNb-based separator multilayer composite structure material and a preparation method thereof. According to the method, NiMoBNb matrix powder, a reinforcing material and amulti-component composite material are used as raw materials, and the NiMoBNb-based separator multilayer composite structure material with different layer thicknesses and different material components is prepared through the technological processes of vibration and mixing, multilayer structure pre-forming, surface treatment and layer-by-layer superposition sintering. The NiMoBNb-based separator multilayer composite structure material can meet the performance requirements of all parts of a separator self-lubricating material, can also be used in extremely severe environments with high temperature, high pressure and high corrosivity, realizes high performance and reliable work, has bearing capacity, compression resistance, high-temperature resistance and corrosion resistance, and particularly has tribological properties effectively meeting the required working requirements; and the application range of a separator is expanded in an environment which is inconvenient to maintain and lubricate, so that the NiMoBNb-based separator multilayer composite structure material has huge potential value and a wide application prospect.

Description

technical field [0001] The invention relates to the technical field of friction, wear and lubrication of mechanical parts of separators in machining centers, in particular to a NiMoBNb-based separator multilayer composite structure material and a preparation method thereof. Background technique [0002] With the rapid development of modern industry, mechanical parts separators face a series of extreme service conditions of ultra-high temperature, dusty wear, strong corrosion, strong radiation and oil-free and grease-free lubrication in the advanced manufacturing field; the main functions of the separator are: To connect and separate two or more parts, currently separator researchers mainly focus on the research on the structure of mechanical parts, often ignoring the material selection and preparation methods of the contact surface of the separator, which makes the separator face blockage in the working process , Corrosion, and ultra-high temperature friction damage problems...
