Abstract

The invention provides a binding-phase-free tungsten carbide hard alloy and a preparation method thereof. The preparation method comprises the following steps: mixing tungsten and carbon under a protective gas or vacuum atmosphere for high energy ball milling to obtain a mixture; and under the protective gas or vacuum atmosphere, sintering the mixture obtained in the above step to obtain the binding-phase-free tungsten carbide hard alloy. The method of preparing the binding-phase-free tungsten carbide hard alloy is simple in process and convenient to operate, and no extra binders are added, and the alloy has a good alloy performance.

Description

technical field

[0001] The invention belongs to the technical field of cemented carbide, and in particular relates to a tungsten carbide cemented carbide without a binder phase and a preparation method thereof. Background technique

[0002] With the development of the world economy and the continuous innovation of industrial technology, the requirements for machining in various fields are increasing day by day. As one of the main materials of machining tools, cemented carbide has been widely concerned about research topics and improvement projects related to it.

[0003] Cemented carbide is an alloy material made of hard compounds of refractory metals and bonding metals through powder metallurgy. Cemented carbide has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance and corrosion resistance, especially its high hardness and wear resistance, which basically remain unchanged even at a temperature of 500°C , I...
