Abstract
The utility model provides a hard alloy and wear-resistant steel blended composite part. The hard alloy and wear-resistant steel blended composite part comprises one or multiple wear-resistant steel layers and one or multiple hard alloy or titanium carbide layers arranged on the wear-resistant steel layer, wherein the multiple wear-resistant steel layers and the multiple hard alloy or titanium carbide layers are staggered. The hard alloy and wear-resistant steel blended composite part provided by the utility model has excellent wear resistance and fastness, and the service life of the hard alloy and wear-resistant steel blended composite part is 2-10 times of the service life of other wear-resistant parts. The hard alloy (WC) or titanium carbide (TiC) are blended with a high wear-resistant material (wear-resistant steel) in a metallurgy blending manner to form a flat surface, an inclined surface, internal and external conical surfaces, internal and external cylinders and stereoscopic surfaces in various shapes of the wear-resistant part or an internal multi-layered composite structure of the wear-resistant part. Compared with a single-layered composite structure formed in a welding manner in the prior art, the multi-layered composite structure has better soundness.
Description
Technical field
The utility model belongs to casting field, is specifically related to the composite members that a kind of carbide alloy and abrasion-resistant stee merge.
Background technology
Carbide alloy is take the carbide of high rigidity refractory metal (WC, TiC) micron powder as main component, take cobalt (Co) or nickel (Ni), molybdenum (Mo) as binding agent, and the sintered metal product that sintering forms in vacuum drying oven or hydrogen reducing furnace.Carbide alloy has a series of premium properties, particularly its high rigidity and wearability such as hardness height, wear-resisting, intensity and toughness is better, heat-resisting, corrosion-resistant, even also substantially remain unchanged under 500 ℃ temperature, still has very high hardness in the time of 1000 ℃.Carbide alloy is widely used as cutter material, such as lathe tool, milling cutter, planing tool, drill bit, boring cutter etc., be used for cutting cast iron, non-ferrous metal, plastics, chemical fibre, graphite, glass, stone material and common iron, also can be used for cutting the difficult to machine materials such as heat resisting steel, stainless steel, potassium steel, tool steel.
Carbide alloy itself has good wearability, with the life-span of its life-span of doing wearing piece far above other metal material wearing pieces.But the hardness of carbide alloy is high, fragility is large, brittle fracture easily occurs during use destroy, and for the normal operation that guarantees workpiece just needs to strengthen the thickness of workpiece, thereby causes the raising of production cost.Analyze to find that most vulnerable parts all be that the surface is working face, and the top layer effective thickness of work with respect to working size also in a very little scope.If the effective thickness of vulnerable part working surface (perhaps being slightly larger than effective thickness) part is the carbide alloy that hardness is high, wearability is good, remainder is preferably cheap material of intensity height, toughness, and when both form alloy, this vulnerable part just also has higher intensity and good toughness when obtaining carbide alloy high rigidity, high-wearing feature, and can save the carbide alloy of a large amount of costlinesses.
At present, be used for the method that wear-resisting carbide alloy generally all adopts built-up welding both at home and abroad, be about to carbide alloy and be welded on the body of workpiece.But, this welding manner, for the carbide alloy than large contact surface, often can not guarantee that in when welding whole contact-making surface all realizes good welding, thereby lose easily effective support when making hard crisp carbide alloy stressed, it is firm not that carbide alloy is combined with bulk material, easily damaged and fall piece during use.
The utility model content
The utility model provides the composite members of a kind of carbide alloy and abrasion-resistant stee fusion for above-mentioned the deficiencies in the prior art, and this composite members has good wearability and fastness.
The utility model is achieved by the following technical solution:
The composite members that a kind of carbide alloy and abrasion-resistant stee merge comprises abrasion-resistant stee layer and the hard alloy layer that is arranged on abrasion-resistant stee layer surface;
It is characterized in that described abrasion-resistant stee layer is one or more layers, described hard alloy layer is one or more layers, and multi-layer wear-resistant steel layer and multilayer hard alloy-layer are crisscross arranged.
The composite members that carbide alloy described in the utility model and abrasion-resistant stee merge has good wearability and fastness, and be 2-10 times of other wearing piece its service life.Carbide alloy in the utility model (WC) merges with the same high abrasion resisting material of the mode of metallurgical casting (abrasion-resistant stee), formed in the three-dimensional surface of plane, inclined-plane, interior male cone (strobilus masculinus), inside and outside cylinder and various shapes at wear part or the wear part the stage construction composite construction; The stage construction composite construction is compared with the individual layer face composite construction that the available technology adopting welding manner forms, and has better fastness.
Description of drawings
Fig. 1 is the structural representation of the composite members of carbide alloy and abrasion-resistant stee fusion.
The specific embodiment
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, the composite members that the utility model provides a kind of carbide alloy and abrasion-resistant stee to merge comprises abrasion-resistant stee layer 1 and the hard alloy layer 2 that is arranged on abrasion-resistant stee layer 1 surface; Described abrasion-resistant stee layer 1 is one or more layers, described hard alloy layer 2 is one or more layers, multi-layer wear-resistant steel layer 1 and multilayer hard alloy-layer 2 are crisscross arranged, and namely except the hard alloy layer 2 on composite members surface, remaining hard alloy layer 2 all is arranged between the two-layer abrasion-resistant stee layer 1.Described carbide alloy is preferably titanium carbide.
