Manufacturing method of super hard metal containing carbon nanotube, the super hard metal manufactured using the same and cutting tools comprising the super hard metal

摘要

The present invention relates to a kind of production ultra-light alloy to contain carbon nanotube, and includes carbon nanotube more particularly, to a kind of production ultra-light alloy, comprising: (one) come formed carbon-metal be used in combination carbon nanotube metal powder; The mixing carbon-metal of b step is compound obtain through step (1) light powder; (3) mixed-powder that molding step obtains is through b step; The formed body sintering that d obtains step is by step c. The present invention can generate ultra-light alloy with good hardness and toughness, by the reaction between minimizing in ultra-light alloy carbon and transition metal carbide, realize increase toughness because adding carbon nanotube to maximize. The ultra-light alloy includes the higher hardness of acquisition and toughness that the method for carbon nanotube generates; Therefore, in the mold for cutting element, abrasion resistance material, heat proof material is made. ;The 2015 of copyright KIPO submissions
