Description
Technical field
The present invention relates to the manufacture method of Metal Substrate wearing composite material, more specifically, the heating power that the present invention relates to be used for metal-WC (tungsten carbide) composite alloy material of surface of the work is cast the mechanical part that oozes manufacture method and obtain thus.
Background technology
By the reinforced metal surface of the work to improve the emphasis that its wearability is wear-resisting area research always.Carbide alloy WC (tungsten carbide) particle and the hard alloy scraps particle that utilizes again thereof have hardness height, characteristics that wearability is strong.It is compound on the surface of the work mutually as wear-resisting, can improves the abrasion resistance of workpiece greatly.In other words, form the metal-base composites that comprises the hard, wear-resistant phase, will significantly improve the wearability of workpiece, improve its service life at surface of the work.In addition, use the hard alloy scraps particle also to have remarkable economical, environmental benefit.
With regard to the preparation method of this composite, currently used method has infiltration method, overlaying method, spraying and cast-infiltration method or the like.But, these methods remain have in some shortcomings to be solved.For example adopt Cu-Mn-Ni (copper-manganese-nickel) alloy that WC particle is soaked into the lip-deep infiltration method of normal steel casting, can form one deck composite layer at surface of the work.The composite of this method manufacturing has certain wearability, but its method complexity, cost height (for example, referring to Chinese patent, the patent No.: ZL 94103404.6, a kind of roller shell of middling speed grinding machine and manufacture method).The simple cost of overlaying method is low, but the product wearability that is obtained can not show a candle to the former.The heat spraying method scope of application has certain limitation because coating thickness generally has only 1～2mm, and with the parent metal poor bonding strength, so its wearability is also poor than the former.Cast-infiltration method has that wearability height, method are simple, low cost and other advantages, but that thickness is oozed in the composite casting is undesirable.Ooze the general method that applies external force that adopts of thickness in order to improve casting, as spun casting, negative pressure casting (people such as Zhang Jun, adopt centrifugal casting that casting surface is carried out alloying, the 61st world's casting meeting, September nineteen ninety-five (Cast SurfaceAlloying by Centrifugal Casting Method, [C], Proceedings of61th World Foundry Congress, Sep 1995)).In addition the WC particle as wear-resisting wild phase is carried out preliminary treatment, in WC particle, sneak into the low-melting-point metal particle and be prefabricated into piece, utilize the low-temperature metal in the molten metal fusing WC particle layer of high temperature casting, ooze the method for purpose＜referring to casting pig surface tungsten carbide particle _ rich chromium cast iron casting infiltration layer research thereby reach casting;＜hot-working method 〉, 1998, (6); P10～11 〉.But it is not high that these methods exist thickness of cast cemented alloy layer, wear-resisting wild phase grain density little (volume share is less than 50%), and wearability not high (No. 45 steel that just quench 4.9～7.6 times), and can only make some miniature workpieces.Can't be widely used in the actual production at present.
Chinese patent application 02106782.1 provides a kind of manufacture method of metal-base composites.But this method is difficult to realize continuous production, particularly for the less workpiece of quality, is difficult to reach casting and oozes effect.And the further stability that improves the quality of production of resulting product of expectation, enhance productivity.
