Description
Technical field
The present invention relates to a kind of alloy powder, refer to a kind of nickel based metal ceramal powder being exclusively used in punch head surface laser melting coating especially.
Background technology
Laser has the feature of high brightness, high directivity, high monochromaticity, high coherence, now just use by increasing field, laser melting coating is exactly the one in process for treating surface.Generally, the principle of laser melting coating utilizes high energy laser beam to irradiate metal material surface exactly, substrate surface is melted rapidly, liquid metal forms a small-scale molten bath, fill in new dusty material simultaneously, in this molten bath, metal material originally mixes mutually with the powder be added, and forms the liquid-metal layer that one deck is new.Treat laser beam through after, liquid-metal layer cools rapidly and forms the solid-state cladding layer of one deck in metal surface thus.Right drift work under bad environment, common drift poor toughness, intensity is low, hardness is little, shock resistance is poor.Be not exclusively used in the metal dust of drift laser melting coating at present, when reality uses, usually common metal dust is utilized to carry out laser melting coating to it, the heat transfer of this metal dust is uneven with melting, and the degrees of fusion between base material is poor, cause a series of defects such as crackle, shrinkage cavity, pore, and drift mechanical performance after laser melting coating falling flat.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of nickel based metal ceramal powder being exclusively used in punch head surface laser melting coating, this nickel based metal ceramal powder is exclusively used in the laser melting coating of drift, improve punch head surface metal structure compactness, thus improve drift, intensity, hardness, impact resistance, guarantee that again it has enough toughness simultaneously.
For solving the problems of the technologies described above, technical scheme of the present invention is: the nickel based metal ceramal powder being exclusively used in punch head surface laser melting coating, by weight percentage, comprise 13-15% carborundum, 0.2-0.3% carbon, 4-6% calcirm-fluoride, 1-4% silicon nitride, 1.5-1.8% vanadium, 2-4% silicon, 7-9% iron, 17-18% molybdenum, 15-17% chromium, surplus is nickel.
Wherein, the nickel based metal ceramal powder optimization formula being exclusively used in punch head surface laser melting coating is: comprise 14% carborundum, 0.2% carbon, 6% calcirm-fluoride, 4% silicon nitride, 1.5% vanadium, 4% silicon, 9% iron, 18% molybdenum, 15% chromium, surplus is nickel.
In nickel based metal ceramal powder in the present invention, the effect of each composition is as follows:
Carborundum (SiC): belong to metal ceramic powder, is present in cladding layer as strengthening particulate, can greatly improves cladding layer hardness and intensity, can reduce the sensitiveness of cladding layer cracking.
Carbon (C): belong to nonmetalloid, carbon content is higher, hardness is higher, anti-wear performance is better, yield point and tensile strength raise, but its toughness, plasticity, impact and corrosion resistance can reduce along with the increase of carbon content, while therefore the selection of C content guarantees that drift meets wearability in this cermet powder, take into account toughness and corrosion resistance as much as possible.
Calcirm-fluoride (CaF
2): as adding material, for reducing internal stress when cladding layer solidifies, after preventing from solidifying, there is the defect such as fire check, shrinkage cavity and porosity, improving the compactness of metal inside tissue.
Silicon nitride (SiN
4): exist as the second ceramic particle except carborundum (SiC), non-fusible in cladding process, but it is large to the thermal absorptivity of laser, heat dispersing can be accelerated, and as the mitigation of soft metallic element and ultrahigh hardness ceramic particle, strengthen creep resistance, non-oxidizability, improve corrosion resistance.
Vanadium (V): there is refined crystalline strengthening and improve resistance to tempering and the effect of the quenching degree of raising material, also can form carbide with carbon, can heat resistance be improved.
Silicon (Si): rise from slag making and protective effect in Self-fusing powder, preferentially can form silicate with the oxygen element entering molten bath, be covered in weld pool surface, prevent liquid metal transition to be oxidized, and improves the wettability of liquid metal.Have larger admittedly molten invigoration effect to ferrite, silicon energy refine pearlite tissue, but the weldability of too high Si to steel is unfavorable.
Iron (Fe): identical with the material of drift matrix, increases the compatibility of liquid metal and matrix, improves the intensity of cladding layer metallurgical binding, makes this cermet powder in fusion full and uniform with punch head surface.
Molybdenum (Mo): as a kind of rare earth element additive, promotes grain refinement, improves the structural homogenity of cladding layer, thus improves the polishing machine of cladding layer.
Chromium (Cr): have stronger solution strengthening ability, improves the intensity of cladding layer, strongly can improve the quenching degree of steel, and have excellent corrosion resistance.Increase mechanical performance and the wearability of steel, the quenching degree of steel and the deformability after quenching can be increased.The hardness of steel, elasticity, coercive force and anti-brute force can be increased again, the corrosion resistance of increase steel and heat resistance etc. simultaneously.
Nickel (Ni): by increasing the retained austenite in cladding layer, improves plasticity and the toughness of cladding layer.By reducing the thermal coefficient of expansion of cladding layer, reducing residual stress, eliminating stress concentrated, thus eliminate crackle and shrinkage porosite.
After have employed technique scheme, effect of the present invention is: this nickel based metal ceramal powder is specifically designed to the laser melting coating of punch head surface, fully can merge with drift base material, each uniform composition is distributed in cladding layer, for the situation of the work under bad environment of drift, adopt ultrahigh hardness ceramic particle to improve the hardness of punch head surface, select some trace elements to improve drift impact resistance and intensity in addition again, also guarantee that there is enough toughness simultaneously, thus make drift can adapt to various severe working environment, increase the service life.
