Abstract
The invention discloses a novel bonding phase ultrafine hard alloy which comprises a hard phase and a bonding phase, wherein the bonding phase is the mixture of iron, cobalt and nickel which have the ratio of 5:2:3 in sequence; the hard phase is ultrafine grain tungsten carbide powder; and the grain size of the tungsten carbide powder is 1.0 to 0.6mum. The novel bonding phase ultrafine hard alloy has certain red hardness due to the tungsten carbide powder; the iron, the cobalt and the nickel are mixed based on ratio, so that the novel bonding phase ultrafine hard alloy has the strength and hardness close to those of cobalt bonding phase ultrafine hard alloy, so that the cost of the production of alloy is greatly reduced.
Description
Technical field
The present invention relates to a kind of wimet, particularly a kind of new bonding phase ultra-fine cemented carbide.
Background technology
Since wimet came out, because cobalt has excellent wettability and good cohesiveness mutually to hard such as wolfram varbides, so cobalt was the most important bonding phase of wimet always.But along with the demand of wimet increases gradually; The consumption of cobalt increases year by year; And cobalt is a kind of rare strategic resource; For solving cobalt resource deficiency and the production cost problem that reduces alloy, countries in the world have all centered on the substitute material of cobalt in the wimet and have carried out extensive studies, and obtain certain achievement and application.Ultrafine gain size is owing to have characteristics such as HS and high firmness, and its product earns widespread respect, but the bonding that has ultrafine gain size at present only is main with single cobalt binder mutually, the production cost of products height.
Summary of the invention
To the problem that prior art exists, the present invention aims to provide a kind of HS, H.T., high-wearing feature and new bonding phase ultra-fine cemented carbide with low cost.
The present invention provides a kind of new bonding phase ultra-fine cemented carbide, comprise the hard phase and bond mutually, and said bonding is the mixture of iron, cobalt and three kinds of elements of nickel mutually.
Preferably, the ratio of said iron, cobalt and nickel is 5:2:3.
Said hard is the superfine crystal particle tungsten-carbide powder of 85wt%～92wt% mutually, and the grain fineness number of said tungsten-carbide powder is 1.0～0.6 μ m.
Said new bonding phase ultra-fine cemented carbide provided by the invention had both had certain red hardness because of tungsten-carbide powder; Have and cobalt binder ultra-fine cemented carbide is close mutually intensity and hardness because of iron, three kinds of element proportional mixing of cobalt and nickel again, and then reduced the production cost of alloy significantly.
Embodiment
Further specify technical scheme of the present invention below in conjunction with embodiment:
The present invention specifically provides a kind of new bonding phase ultra-fine cemented carbide, comprise the hard phase and bond mutually, and said bonding is the mixture of iron, cobalt and three kinds of elements of nickel mutually.
The present invention does not limit said iron, cobalt and three kinds of element blended of nickel ratio, but the ratio of above-mentioned in the present embodiment three kinds of elements is preferably 5:2:3.
Said hard is the superfine crystal particle tungsten-carbide powder of 85wt%～92wt% mutually, and the grain fineness number of said tungsten-carbide powder is 1.0～0.6 μ m.
Said new bonding phase ultra-fine cemented carbide provided by the invention had both had certain red hardness because of tungsten-carbide powder; Have and cobalt binder ultra-fine cemented carbide is close mutually intensity and hardness because of iron, three kinds of element proportional mixing of cobalt and nickel again, and then reduced the production cost of alloy significantly.
Above the present invention has been carried out exemplary description; Obvious realization of the present invention does not receive the restriction of aforesaid way; As long as the various improvement of having adopted technical scheme of the present invention to carry out; Or design of the present invention and technical scheme are directly applied to other occasion without improving, all in protection scope of the present invention.
