Description
Technical field
The invention belongs to the material technology field, particularly a kind of surfacing alloy material of impact-resistant and high-wear-resistant.
Background technology
Wearing and tearing are one of three big reasons of material damage; In industries such as mine, metallurgy, machinery and electric power; Some critical component great majority on the equipment are in to have under the impact wear situation for a long time works, and the wearability of workpiece has become one of principal element that determines its service life.These wearing pieces mainly impact mutually with mineral and sand grains and rub; The wearing and tearing that receive in the course of the work according to wear parts can classify as abrasive wear with it; This wear type probably accounts in industry more than 50%, for example, and disintegrating machine tooth plate, tup, beater plate; Ball grinding machine lining board, abrading-ball; The middle plates of scraper plate machine etc. all are under sharp-pointed and hard abrasive material effect, to produce plow, roll with crackle and peel off gradually, and are worn out or because crackle is expanded ruptures until part.
The surface overlaying high-abrasive material is one of effective way that improves workpiece service life, and domestic wear-resisting alloy material is more at present.
China applies for a patent " heat-resistant and wear-resistant solder stick for pile-up welding " and (CN86106019) has designed a kind of welding rod that can be used for the built-up welding of metal mine easy-abrasion part; Have that manufacturing process is simple, the advantage of good welding performance; But adopt welding rod built-up welding efficient lower, and be unfavorable for realizing the automation welding.
China applies for a patent " a kind of built-up welding is with bag core welding wire " and (CN1415453A) has designed a kind of built-up welding with bag core welding wire; Can be applied to field of surface treatment such as petroleum industry machinery, downhole tool, but the shortcoming of flux-cored wire is that manufacturing process is complicated, price is more expensive.
China applies for a patent " Fe-05 surfacing welding alloy powder agglomates " and (CN85102440) has designed a kind of alloy powder block that built-up welding is used that improves; This kind alloy powder block need not metallurgy and casting process in manufacture process; Have advantages such as manufacturing process is simple, but the main hard of this alloy is Cr mutually

6, its microhardness value as the wear-resisting skeleton in the antifriction alloy, can't satisfy higher wearability requirement sometimes between HV1000～1300.
China applies for a patent " a kind of wear resistant alloy material " (CN 100371489C) and has designed a kind of wear resistant alloy material, and this alloy adds boron when composition designs, and forms the carbon-boron compound of the higher chromium of hardness; In alloy, add simultaneously rare earth, refinement the hard phase in the alloy, obviously improved the wearability of alloy; But this alloy crackle when surface overlaying is more; When using when long, wearing layer is prone to peel off, and reduces workpiece service life.
Summary of the invention
Technical problem to be solved by this invention is the deficiency that overcomes above-mentioned prior art; A kind of surfacing alloy material of impact-resistant and high-wear-resistant is provided; This material cost is lower, when using operating procedure simple, can realize automation mechanized operation; The product of built-up welding has good impact resistance and wear resistance, and service life is longer.
The surfacing alloy material composition of impact-resistant and high-wear-resistant of the present invention is ferrochrome 55～68%, ferro-boron 5～13%, boron carbide 0.5～1.5%, sodium KP1 8～15%, silicomangan powder 1～4.5%, nickel powder 0.5～6.5%, vanadium iron 0.2～5%, molybdenum-iron 0.5～7.5%, ferro-niobium 1.5～6%, magnesium-rare earth 1.5～5%, graphite 0.1～2.8% by weight percentage; Surplus is an iron; Granularity is 70～140 orders; Wherein the weight content of magnesium is 20～26% in the magnesium-rare earth; Surplus is lanthanum or cerium, and the percentage by weight of silicon is 25～50% in the silicomangan powder, and surplus is a manganese.
The preparation method of the surfacing alloy material of impact-resistant and high-wear-resistant of the present invention is:
With granularity is that 70～140 purpose ferrochrome, ferro-boron, boron carbide, silicomangan powder, sodium KP1, nickel powder, vanadium iron, molybdenum-iron, ferro-niobium, magnesium-rare earth, graphite and iron powder mix by said ratio; Place the mould briquet then; Natural air drying is 24h at least; Under 50～60 ℃ of conditions, dry 0.5～1h then, be warming up to again under 150～300 ℃ of conditions and be incubated 1～5h.
Product of the present invention is started with from the wearability and the impact resistance that improve alloy, takes into account the combination property consideration, and the alloy organizing characteristic is that the carbide with the carbon-boron compound of the higher chromium of hardness and silicon is main hard hardening constituent, has greatly improved the wearability of alloy; Add activator and inovulant in the alloy, improved the binding ability of hard wild phase and matrix, reduce the generation of crackle, improved the bond strength of wearing layer and surface of the work simultaneously, obviously improved the impact resistance of alloy.
1, existing high-abrasive material is when built-up welding, and the particle of hard wild phase is comparatively thick, is net distribution usually; When bearing friction and wear, peel off easily, unfavorable to the alloy wearability, so the present invention adds magnesium-rare earth as inovulant in alloy; In the refinement carbon-boron compound; The reticulated carbon boron compound is broken off, and the carbon-boron compound in the alloy distributes more even, helps improving the wearability of alloy.
2, existing high-abrasive material is in weld deposit process, and wearing layer and surface of the work bond strength are not enough, and wearing layer is prone to peel off in when long, using.The high-abrasive material that the present invention designed is introduced magnesium-rare earth; Improved the activity of wearing layer, wearing layer and matrix alloy compatibility are better during the built-up welding fusing, obviously form transition zone between matrix and the wearing layer; Discharged the thermal stress between matrix and the wearing layer; Alleviate not matching of the two elastic modelling quantity, reduced peeling off of wearing layer, improved the service life of workpiece.
3, introduce silicomangan among the present invention, silicon combines to form hard carbon-silicon compound mutually with carbon during built-up welding, is evenly distributed in the wearing layer; Help improving the hardness of wearing layer on the one hand; The carbon-boron compound that cuts off bulk on the other hand slows down the stress between the carbon-boron compound, reduces the generation of crackle.
The surfacing alloy material that the present invention designed can be applied to preparation of wearing piece composite surface material and surface of the work reparation; Macrohardness height, strong shock resistance and the alloy of alloy in use seldom have crackle to produce; Have very strong wear-resistant grain polishing machine, range of application very extensively.
