High-strength cermet for cutting non-ferrous metal sheet and preparation method thereof

Abstract

The invention discloses a high-strength cermet for cutting non-ferrous metal sheets and a preparation method thereof, wherein the preparation method comprises the following steps: a. taking primary TiC powder, primary Mo powder, primary Ni powder and NbC powder and passing them through a ball milling medium After grinding for 48h-64h, the slurry is obtained, wherein the average Fischer particle size of the primary TiC powder is ≤1.0 μm, and the mass ratio is 44%-46%, and the average Fischer particle size of the primary Mo powder is ≤1.0 μm, and the mass ratio is 14% %-16%, the average Fischer particle size of primary Ni powder is ≤1.0μm, and the mass proportion is 38%-40%, the average Fischer particle size of NbC powder is ≤1.0μm, and the mass proportion is 0.8%-1.2%, the ball milling medium It is cemented carbide baseball and absolute ethanol, or the ball milling medium is cemented carbide baseball and No. 120 aviation gasoline; b, the slurry after step a is made to enter the stainless steel container through a stainless steel screen; c, the slurry is placed on the stainless steel After standing still in the container for 24 hours, and when the ball milling medium is cemented carbide baseball and absolute ethanol, the absolute ethanol on the upper layer of the slurry is taken out.

Description

Technical field [0001] The invention relates to a cermet and a preparation method thereof, in particular to a high-strength cermet for cutting non-ferrous metal sheets and a preparation method thereof. Background technique [0002] Special materials are often used for the cutting and forming of non-ferrous metal sheets. With the development of modern industry, people's exploration and research on cutting and forming materials are constantly being updated. How to develop cutting and forming with excellent performance and low cost The use of materials has become a key issue for related researchers and engineers. The cutting and forming of tin steel sheets for transformers in the prior art usually uses steel-bonded gold. However, the steel-bonded gold itself has the disadvantages of high cost and low service life. [0003] In view of this, it is necessary to provide a new type of high-strength cermet for cutting non-ferrous metal sheets to overcome or alleviate the above-mentioned de...
