Abstract
The ageing hardened tool steel alloy powder preparation is characterized by its chemical composition formed from (wt%) Co 5-25%, Ni 1-14%, Mo 0-16%, W 0-20%, Fe-Mo 0-26%, Fe-W 0-25%, Ti 0-4%, Fe-Ti 0-6%, Al 0-3%, RE 0-1%, Te 0-1%, Se 0-1%, Cr 0-1% and the rest is Fe. Said alloy powder can form alloy layer with excellent performance on the surface of work piece by means of surfacing, deposition and spray-coating process, it is not easy to produce crack under the condition of quickly-cooling, after having been aged, its hardness can be up to HRC 65-67, so that said invented product can be used for making and repairing high-performance superhard die, roll, valve and tool cutter, etc..
Description
A kind of age hardening tool steel alloy powder belongs to metal pulvis manufacturing technology field.
Age hardening tool steel is meant to have the typical tool materials characteristic, but do not resemble existing general tool steel and separate out the generation secondary hardening by carbide, but separate out promptly usually said timeliness, a kind of novel tool material of acquisition high rigidity and heat resistance by intermetallic compound.The age hardening tool steel carbon content is extremely low, and is not high in as-quenched condition hardness, carries out machining easily, and hardness increases substantially after the timeliness, can be used for the manufacturing of high hardness wear-resisting part.But, influenced the practical application of this kind steel alloy in industrial production because age hardening tool steel needs vacuum metling, material price costliness, forgeability not ideal.
Surfacing, deposited and thermospray are three kinds of workpiece surface modification methods commonly used in the engineering, and these three kinds of methods can be by deposited certain powdered alloy or be coated on the piece surface, and make part have properties such as wear-resisting, heat-resisting, corrosion-resistant.But traditional high hardness wear-resisting alloy powder all is to make metal strengthening by separating out of carbide at present, because its carbon content height, deposited metal toughness is very poor, very easily crack, and hardness does not satisfy the requirement of using yet.
The object of the present invention is to provide a kind of high rigidity, high tenacity, high red hardness and have the age hardening tool steel alloy powder of excellent abrasive resistance.
The weight proportion that the invention is characterized in raw metal is: Co:5～25%, Ni:1～14%, Mo:0～16%, W:0～20%, Fe-Mo:0～26, Fe-W:0～28, Ti:0～4%, Fe-Ti:0～6%, Al:0～3%, RE:0～1%, Te:0～1%, Se:0～1%, Cr:0～1%, all the other are Fe, and RE is a mishmetal, have at least a kind of non-vanishing in each optional ingredient.
Above-described raw metal can be selected for use thread, block, powdered metal or alloy.
This welding wire deposited metal composition is (weight %): C :≤0.03%, and Co:3～25%, Ni:1～14%, Mo:3～18%, W:5～25%, Ti:0～2%, Al:0～2%, RE :≤0.06%, Te :≤0.05%, Se :≤0.05%, Cr :≤0.5%, Mn :≤0.5%, Si :≤0.5%, P :≤0.02%, S :≤0.02%, surplus is Fe.
Alloy powder adopts the metal powder common process to make, and selects various raw metals such as thread, block, powdered metal or alloy during making for use, adds in proportion and through vacuum or inert gas shielded melting, passes through rare gas element again and dusts and make alloy powder.In alloy powder making processes, the vacuum tightness of strict control melting and the purity of rare gas element reduce C in the starting material, S, the content of impurity components such as P to greatest extent.
The invention provides a kind of age hardening tool steel alloy powder of excellent performance.This alloy powder passes through surfacing, working methods such as deposited or thermospray, deposited or the overlay that forms on piece surface has typical tool steel characteristic, deposited or overlay is difficult for cracking under the fast speed cooling conditions, hardness is about HRC45, carry out machining easily, hardness increases substantially and can reach HRC65～67 after the timeliness, the non-notch notched bar impact strength is about 30J, red hardness was higher than traditional rapid steel when toughness was identical, be heated to 650 ℃, be incubated that hardness HRC is about 60 after 4 hours, anti-temper softening is higher about 100 ℃ than traditional rapid steel, it is bad to have overcome traditional high hardness wear-resisting alloy powder toughness preferably, the deficiency that splitting resistance difference and hardness are not high, but also have better red hardness.This alloy powder can be used for manufacturing and the reparation that the superhard mould of high-performance, roll, valve and cutter etc. require high rigidity, high tenacity, high-wearing feature and red hardness part.
