Embodiment 1

[0018] A preparation method of a titanium-based alloy tool material, which is prepared from the following raw materials:

[0019] Mo 2 C powder: purity>99.5%, Fischer particle size 2.7μm, 10Kg;

[0020] Ni powder: purity>99.5%, Fischer particle size 2.3μm, 20Kg;

[0021] Fe powder: purity>99.5%, Fischer particle size 30μm, 11Kg;

[0022] TiC powder: purity>99.5%, Fischer particle size 2.5μm, 47Kg;

[0023] WC powder: purity>99.5%, Fischer particle size 1.0μm, 12Kg.

[0024] The above weighed Mo 2 C, Ni, Fe, TiC and WC are added to the ball mill tank, and 85L of absolute ethanol is poured into the ball mill tank at the same time, and the wet ball mill is mixed under the action of absolute ethanol. The ball-to-material ratio of the ball mill is 5:1 (weight ratio), the ball milling time was 24 hours.

[0025] After the ball milling is completed, the mixture is dried with steam at a drying temperature of 120° C. and a drying time of 6 hours. Next, the mixed material is pass...

Abstract

The invention discloses a titanium-based alloy cutter material and a preparation method thereof. Weighed Mo2C, Ni, Fe, TiC and WC are added into a ball-milling tank, meanwhile, a ball-milling medium is poured into the ball grinding tank, wet ball-milling mixing is conducted under the action of the ball-milling medium, after ball-milling mixing, the mixture is successively dried and screened, a molding agent is added into the screened mixture, the mixture is pressed into a blank through a hydraulic press, and the blank is sintered by vacuum. According to the titanium-based alloy cutter materialand the preparation method thereof, W is partially replaced with Ti, Co is partially replaced with the Fe, the cost is effectively lowered, and strategic materials are saved; and furthermore, the Mo2C and the Ni are effectively combined, the strength and wear resistance of the material are improved, and the service life of the material is greatly prolonged, so that the hardness and strength of the material both meet the use requirements.

Description

technical field [0001] The invention relates to the technical field of cemented carbide tool materials, in particular to a titanium-based alloy tool material and a preparation method thereof. Background technique [0002] With the development of aerospace industry, weapons industry, electronics industry and modern machinery industry, higher requirements are put forward for the performance of product parts and materials. Therefore, many difficult-to-machine materials appear in modern engineering materials, such as: ultra-high-strength steel, superalloy, titanium alloy, chilled cast iron, etc. It is difficult to cut these materials because of their high hardness, high strength, low plasticity and high brittleness, low thermal conductivity, microscopic hard points or hard inclusions, and too active chemical properties. On the other hand, due to the pursuit of precision, efficiency and environmental protection in manufacturing technology, high-speed cutting, hard cutting, and d...
