Description
Technical field
The present invention relates to a kind of nano TiC
0.5Particle in-situ Reinforced Cu (Al) matrix material and preparation method thereof.
Background technology
Strengthen the matrix material that copper or copper alloy are formed by one or more ceramic phases, the satisfactory electrical conductivity of existing copper and thermal conductivity, high intensity and toughness, the characteristic such as high temperature resistant, corrosion-resistant, wear-resistant that has pottery again, have been widely used in fields such as electrician, chemical industry, traffic, machineries, be widely applied to fields such as electrical contact, electric switch, heat exchanger.Yet the interface wet ability between copper and the most of pottery is relatively poor, makes that the preparation of ceramic Reinforced Cu-Base Composites is relatively more difficult.
In recent years, nano particle strengthens Cu-base composites, makes it reach excellent mechanics, tribological property, causes extensive concern.Yet, the wild phase particle directly is added to traditional preparation process method in the copper matrix, the wild phase particle often can not be dispersed in the copper matrix, and cost is higher.Therefore, can have strong interface to combine, have the nano particle reinforced effects again with copper, and the material of preparation process economy be investigators pursue always.
