Abstract

The invention belongs to the technical field of hard alloy production and discloses a nickel-for-cobalt hard alloy material and a preparation method and application thereof. According to the nickel-for-cobalt hard alloy material and the preparation method and application thereof, refined paraffin is adopted as a molding agent; ball milling, drying for granulation, compression molding and sinteringare conducted, so that the novel hard alloy material low in cost and high in performance is prepared; and in the preparation process, molybdenum powder is added, and wettability of nickel powder andtungsten carbide powder is improved; low-temperature sintering and pressure sintering are adopted for sintering molding treatment; and argon gas is adopted as a carrier, and the porosity of products can be reduced while it is guaranteed that the products are small in crystal grain size.

Description

technical field [0001] The invention belongs to the technical field of hard alloy production, and more specifically relates to a nickel-substituted cobalt hard alloy material and a preparation method and application thereof. Background technique [0002] Cemented carbide consists of hard compounds of refractory metals and binder metals (mainly cobalt). Due to the increasing demand for cemented carbide and the limited cobalt resources in the world, finding and researching alternative materials for cobalt has always been a directional topic in the research and production of cemented carbide. In recent years, experts and scholars from all over the world are studying new resources of new cemented carbide materials, among which nickel substituting cobalt has become a research hotspot. [0003] However, some of the existing nickel-substituted cobalt cemented carbides will produce large-grained nickel aggregates that do not exist in fine-grained nickel powders during wet grinding,...
