Abstract

The invention discloses nickel, molybdenum, iron, chromium and diamond alloy composite powder and a preparation method and application thereof, and belongs to the field of diamond composite material processing. The nickel, molybdenum, iron, chromium and diamond alloy composite powder is composed of the following components in percentage by mass of 62-80% of diamond, 5.2-13.68% of Mo, 0.2-0.76% ofFe, 0.18-0.57% of Cr, 0.076-0.3% of Cu and balance of Ni. The nickel, molybdenum, iron, chromium and diamond alloy composite powder provides composite powder materials with excellent anti-corrosion,wear-resistant and anti-oxidation functions for laser thermal spraying, supersonic flame spraying, plasma spraying, etc.

Description

technical field [0001] The invention belongs to the field of metal powder material technology and advanced manufacturing application, and specifically relates to a nickel-molybdenum-iron-chromium-diamond alloy composite powder manufacturing technology, which is mainly used for supersonic flame thermal spraying, plasma thermal spraying and laser high-speed thermal spraying. Background technique [0002] Hard surface materials have developed from cemented carbide to surface coating, mainly including surface coating, spraying WC and superhard alloy surfacing. In the field of diamond wear-resistant applications, there are mainly diamond coatings, or diamond monolithic materials such as diamond indenters. Due to the high hardness and brittleness of diamond itself, it is neither economical nor durable to use as a monolithic material. [0003] In order to obtain higher wear resistance, diamond or diamond-like coatings, coatings and monolithic diamond composites have gradually attra...
