Description
Technical field
The present invention relates to a kind of alloy material, specifically a kind of wear resistant alloy material that can be used for built-up welding and casting.
Background technology
In recent years, the anti-abrasive material technology has obtained the development of advancing by leaps and bounds, and wherein high-chromium alloy is used the most general in industrial production as a branch of anti-abrasive material.The development of high-chromium alloy starts from casting at first.Casting Gao Ge (alloy) white pig iron is general to be used at hypoeutectic to the eutectic composition section, cooperates the optimization of Heat Treatment Process performance, is celebrated more famous alloy such as Cr15Mo3 etc. with its high rigidity and high-wear resistance.With the parallel development of casting high chromium white iron be the high-chromium alloy hardfacing materials, the general eutectic that uses is to the hypereutectic composition section, use down as-welded, its macro manifestations is that hardness and wear resisting property are higher, and the trade mark that more famous resurfacing welding material such as Switzerland Ka Situolinetedi company produce is 6715 the surfacing welding electrode and the built-up welding medication cored welding wire of same alloy composition thereof.
High-chromium alloy is why wear-resisting to be determined by its heterogeneous microstructure.The bulk alloy composition characteristic of high-chromium alloy is Gao Ge (〉=12%) and high-carbon (〉=2%).
The casting high-chromium alloy is generally got the hypoeutectic composition, contains a large amount of eutectic carbides (Cr in its microtexture
7C

23C
6Deng) the hard phase, these hard mutually and strong, matrix is combined preferably for toughness, obtains good abrasion resistance properties.Thermal treatment process is mainly used to regulate the matrix metal performance.
The built-up welding high-chromium alloy is generally got hypereutectic composition, not only contains the eutectic carbides phase in its microtexture, but also contains primary carbide (Cr
7C
3) phase.Because primary carbide phase (also claiming a second phase) is bigger with respect to eutectic carbides phase (also claiming two second phases) grain-size; shade protective effect to the matrix alloy tissue in wear process is more obvious, therefore shows higher wear resistance than the casting high-chromium alloy.
In wear-resistant field, pursue alloy have more high abrasion resistance can and comprehensive performance be the main flow direction that material is innovated.High-chromium alloy can realize that the essential reason of high-wearing feature is to contain high rigidity " chromium carbide " hard phase in the alloy.Studies show that contained hard phase hardness is high more in the alloy, its wear resisting property is good more.In this sense, the weakness that high-chromium alloy exists is that hard phase hardness is on the low side, Cr

6Hardness be respectively: HV1300 and HV1000 have restricted the further raising that this system alloy wear-resisting decreases performance.
Summary of the invention
Technical problem to be solved by this invention is to overcome above-mentioned the deficiencies in the prior art, providing a kind of is the hard phase with high rigidity metal carbon-boron compound, the macrohardness height, hard combines with matrix firmly, has very high wear-resistant grain polishing machine, impact wear resistance and Chinese People's Anti-Japanese Military and Political College's angle erosive wear performance, the wear resistant alloy material that has wide range of applications.
The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of wear resistant alloy material is characterized in that: alloy composition content (weight %) is: C 0.8-5, Cr 9-30, Nb 0.3-9, V 0.1-2, Mo 0.3-5, B 0.2-5, Ni 0.5-6, rare earth 0.01-2, surplus are Fe.
The present invention starts with from improving hard phase hardness, takes into account over-all properties and considers, and the Microstructure characteristics of alloy is the carbon-boron compound (Cr with chromium
7(C, B)
3Be main hard strengthening phase, there is a large amount of complicated metal carbon-boron compound phases in the eutectic matrix tissue, against existing technologies, the carbon-boron compound phase microhardness of chromium is the essential place of improving the alloy wear-resisting performance between HV1600～1900 in the alloy of the present invention.A large amount of complicated metal carbon-boron compound phase disperse and being evenly distributed among the eutectic phase of alloy substrate plays supplementary function to the wear resisting property of alloy.When abrasive particle wore and tore to alloy surface, the carbon-boron compound of chromium played wear-resisting skeleton function mutually, and alloy substrate is produced the shade protective effect mutually.Eutectic metal carbon-boron compound is strengthened the wear resistance of matrix self mutually.Rare earth plays the nucleating agent effect in the deposited metal crystallisation process, make deposited metal crystal grain, and particularly tiny the and uniform distribution of carbon-boron compound crystal grain all has active effect to improving hardfacing alloy substrate tissue toughness and alloy monolithic wear resistance.
The hypoeutectic of alloy system of the present invention and eutectic composition section can be used for casting wear-resistant spare; Hypoeutectic, eutectic and hypereutectic composition section can be made surfacing welding electrode, flux-cored wire, block resurfacing welding material or powder weld deposition material.The macrohardness height of this alloy, hard combines firmly with matrix, has very high wear-resistant grain polishing machine, impact wear resistance and Chinese People's Anti-Japanese Military and Political College's angle erosive wear performance, range of application is very extensive.
