Embodiment 1

[0030] A small piece of cobalt material is placed on the tungsten carbide plate, and the cobalt is melted by means of instantaneous arc heating. The measured angle between the cobalt and the tungsten carbide plate is 45°.

Embodiment 2

[0032] 96wt% cobalt, 1wt% aluminum, 1wt% titanium, 1wt% iron and 1wt% nickel are smelted by vacuum melting (VIM) to obtain a bonded metal block, and a small piece of bonded metal is placed on a tungsten carbide plate, and the electric arc is used to The instant heating method will combine the melting of the metal and measure the angle between it and the tungsten carbide plate to be 30°.

Embodiment 3

[0034] 93wt% cobalt, 1wt% aluminum, 2wt% titanium, 2wt% iron and 2wt% nickel are smelted by vacuum melting (VIM) to obtain a bonded metal block, and a small piece of bonded metal is placed on a tungsten carbide plate, and the arc is used to The instant heating method will combine the melting of the metal, and the angle between it and the tungsten carbide plate is measured to be 21°.

Abstract

A carbide / bonded metal composite powder, comprising 80% to 97% by weight of carbide; and 3% to 20% by weight of bonded metal powder, wherein the bonded metal powder contains cobalt and a first metal Powder, the first metal powder contains one or a combination of aluminum, titanium, iron and nickel, and the content of cobalt accounts for 90%-99% of the combined metal powder.

Description

technical field [0001] The present invention relates to carbide / binding metal composite powder, especially to composite powder with cobalt as the main component of bonding metal. Background technique [0002] Cutting tools, molds, and workpieces are important tools for mass production of products. Whether it is the upgrading of electronics, communications, optoelectronics, precision machinery, or transportation tools, it depends on the improvement of the technical capabilities of these industries. At the same time, under the pressure of global competition and the rapid changes in the overall environment, the mold and tool industry plays a key role in assisting industrial upgrading, which is very important to industrial development. [0003] However, the hardness, wear resistance, and high temperature resistance of tools, molds, and workpieces directly affect the service life of molds, and jointly affect the quality and function of back-end products, while the manufacturing p...
