Abstract

The invention relates to a high-strength titanium diboride particle-reinforced copper-based composite material used for heavy equipment, and a preparation method thereof. The high-strength titanium diboride particle-reinforced copper-based composite material is composed of the following components, by volume percentage, of 6-9% of high-purity titanium diboride with the purity greater than 98%, and 91-94% of copper alloy ZCuSn5Zn5Pb5. The high-strength titanium diboride particle-reinforced copper-based composite material used for the heavy equipment is prepared through the steps of smelting, stirring, heat insulation, casting and the like. According to the high-strength titanium diboride particle-reinforced copper-based composite material used for the heavy equipment, which is provided by the invention, the strength, the hardness, the slide speed and the service life of the copper alloy ZCuSn5Zn5Pb5 are increased and prolonged while the original wear resistance and corrosion resistance thereof are ensured by virtue of the characteristics of a high melting point, corrosion resistance, high hardness, good heat stability, high-temperature oxidization resistance and the like of the high-purity titanium diboride, and therefore the requirements for applications of the high-strength titanium diboride particle-reinforced copper-based composite material to the heavy equipment are met.

Description

technical field [0001] The invention relates to a copper-based alloy composite material and a preparation method thereof, in particular to a high-strength titanium diboride particle-reinforced copper-based composite material for heavy equipment. Background technique [0002] The casting method is in accordance with the national standard GB / T1176-2013 standard national standard copper alloy ZCuSn 5 Zn 5 Pb 5 It is a multi-purpose casting bronze material, which has good wear resistance and corrosion resistance, easy processing, good casting performance and good air tightness. Therefore, it is mainly used in the manufacture of wear-resistant and corrosion-resistant parts that work under relatively high loads and medium sliding speeds (4m / s), such as bearing bushes, bushes, cylinder liners, pistons, clutches, pump parts, glands, turbines, etc. . However, due to the copper alloy ZCuSn 5 Zn 5 Pb 5 Due to the material itself, the application in heavy equipment is greatly res...
