High-temperature-resistant metal powder friction material

Abstract

The invention discloses a high-temperature-resistant metal powder friction material. The high-temperature-resistant metal powder friction material comprises the following raw materials of, by weight,40-45 parts of iron powder, 10-13 parts of molybdenum dioxide, 2-4 parts of wollastonite, 2-4 parts of high-purity quartz stone powder, 5-8 parts of nickel powder, 3-5 parts of chromium powder, 1-3 parts of silicon nitride and 2-4 parts of boron nitride. According to the high-temperature-resistant metal powder friction material, the silicon nitride and the boron nitride are added into the frictionmaterial, so that the high temperature resistance of the friction material can be effectively improved, the friction material can effectively resist the high temperature of 1500-1800 DEG C, and the application range is greatly expanded; and the friction material is excellent in mechanical property and friction property, can operate at a high speed and under a high load, and has a good applicationprospect.

Description

technical field [0001] The invention relates to the technical field of friction materials, in particular to a high temperature resistant metal powder friction material. Background technique [0002] In recent years, iron-based powder metallurgy materials have developed rapidly, mainly because they save non-ferrous metals, show better friction properties under high temperature and high load, have high mechanical strength, and can withstand relatively large pressures, so they are used in many fields. However, since iron has a strong affinity with the couple, which is beneficial to the development of the bonding process, it is necessary to add a large number of other elements to alloy iron to reduce the plasticity of iron and increase its strength, yield limit and hardness to overcome the secondary disadvantages , but it also increases the cost and processing complexity. The main purpose of adding chromium, nickel, and molybdenum to the matrix components of iron-based material...
