Description
Technical field
The present invention is a kind of ceramic tool material and preparation method thereof, particularly has TiCN based ceramic metal of stainless steel binding agent and preparation method thereof.
Background technology
Since the nineteen twenty-three invention, the WC-Co series hard metal is the main material of machining always.The W and the Co that are used to make Wimet are rare strategic resources, and according to US Geological Survey's statistics in 2000, world's tungsten reserves are 3,700,000 t, and the reserves basis is 5,800,000 t.World's tungsten reserves mainly concentrate on China, Russia, Canada and the U.S., and four countries account for 84% of world's total amount.In world's tungsten reserves, China accounts for 66%, occupy first place in the world, but all things considered, tungsten remains a kind of rare strategic resource, W price increase on the domestic and international market.World Co reserves (not containing China) are about 4,500,000 tons at present, and the reserves basis is 9,600,000 tons, and mainly is distributed in the African country of political turbulence; And China Co resource shortage, inserted tool accounts for 70% of national Co consumption, Co output can not satisfy domestic needs, half needs import, the supply of material of Co and conditions of demand complexity, very unstable (in non-turbulent political situation, supply of material difficulty; The Russia economy instability, prospect of export is uncertain), cause the price volalility amplitude of Co bigger.And it is reported that lung cancer is relevant with the powder that suction contains Co.Therefore cemented carbide industry wishes to reduce the consumption of Co and the substitute of searching Co.
The sintering metal of exploitation few (nothing) W, Co is extremely urgent.TiCN is verified can replace WC and do the hard phase, and Fe belongs to the iron family metal together with Co, Ni in the periodic table of elements, and density, fusing point, atomic radius are close, and physics, chemical property are close, are the candidates of replaced C o.The more important thing is that it is many that Ni and Fe resource will be enriched, first of China Ti resource tool world, account for the world and exploited 64% of reserves that this accounts for only 0.7% the area Ti resource of then containing the whole nation 93% of area the Panxi Diqu in Sichuan Province, has comparative advantage; Fe more can be described as a kind of popular metal.Patent 98808562.3 discloses the blade that a kind of sintering metal that contains Co-Ni-Fe-binder is made.This blade comprises the Co-Ni-Fe binding agent of at least a hard constituent element (WC or TiCN) and about 2-19wt%.The characteristics of described Co-Ni-Fe binding agent are: even when viscous deformation took place, described binding agent still kept its face-centered cubic (fcc) crystalline structure constant basically, and, can avoid occurring the transformation of stress and/or strain-induced.
Although in recent years Fe has been done more research for the Co Wimet, because Fe is bad to the wettability of hard phase, the iron powder wet-milling is difficult for disperseing, and the alloy porosity of making is big, characteristics such as easy oxidation and rusting.Therefore, at present, the sticking Wimet of Fe base alloy has only obtained limited application at several fields such as mine instrument, wear parts, and at typical hart metal product---use seldom in the cutting tool field.The present invention overcomes above-mentioned technological problems, has prepared the TiCN-Fe sintering metal cutting tip of excellent performance.The ceramic tip that the present invention makes has high hardness and wear resistance, erosion resistance, and low porosity and low cost and strategic resource consumption can be used for (partly) precision work of soft steel.
