Abstract

The invention discloses an alloy powder manufactured by high pressure water atomization, and the compositions (weight percentage) of the alloy powder are: 0 to 60 percent of copper, 20 to 50 percent of iron, 5 to 20 percent of nickel, 0 to 15 percent of cobalt, 0 to 15 percent of tin, 0 to 5 percent of molybdenum, 0 to 5 percent of titanium, 0 to 5 percent of rare earth elements, 0 to 5 percent of aluminum, and 0 to 5 percent of silicon. Materials are high temperature molten and alloyed according to a certain proportion and are atomized by high-pressure water; the obtained alloy powder is dried, reduced by hydrogen, finally the atomized alloy powder is prepared. The alloy powder can be taken as a bonding agent for producing diamond tools and replace the originally used cobalt powder and nickel powder; the alloy powder can achieve performances no less than the original cobalt or nickel composition bonding agents, and greatly reduce the manufacturing cost of diamond tools.

Description

technical field

[0001] The invention relates to the field of powder alloys, in particular to an atomized alloy powder that replaces independent components of cobalt and nickel materials in a bond of a diamond tool. Background technique

[0002] As we all know, cobalt is a metal with good comprehensive performance in diamond tool bonds, but cobalt is very expensive, and cobalt resources in my country are very scarce. Nickel is also a precious metal second only to cobalt in diamond tool bonds. Expensive and scarce resources, there is an urgent need for an alternative product, which can maintain the original properties (mechanical properties and cutting properties) of the binder, while the raw materials of the product are readily available and the cost is reduced. Contents of the invention

[0003] In view of the scarcity and high price of original diamond tool binder resources at home and abroad, the present invention provides an atomized alloy powder as a diamond tool binder...
