In the process of the continuous fiber laser cladding, the nickel metal ceramal powder can greatly improve the laser absorbing rate of a metal piece, can form a cladding layer which is provided with a compact internal tissue structure and is free of defects such as cracks, shrinkage cavities and bubbles on the surface of the metal piece, greatly prolongs the service life of the metal piece, and reduces production cost.
Description
Technical field
The invention discloses cermet powder, particularly a kind of nickel based metal ceramal powder that is exclusively used in the cladding of continous way optical-fiber laser.
Background technology
Laser has high brightness, high directivity, high monochromaticity, high coherence's feature, just by increasing field, is used now, and wherein laser melting coating is exactly a kind of in process for treating surface.That summarizes says, the principle of laser melting coating utilizes high energy laser beam to expose to 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 being added, and forms the new liquid-metal layer of one deck.After treating laser beam scanning, liquid-metal layer is the cooling solid-state cladding layer of one deck that forms in metal surface thus rapidly.
Yet, on domestic market, almost there is no the metal dust of continous way optical-fiber laser cladding special use, common used alloy powder is mostly thermal spraying self-fluxing alloy powder used.Due to differences such as the heat transfer type of two kinds of technology, process conditions, thermal spraying self-fluxing alloy powder used is directly used in after the cladding of continous way optical-fiber laser, and laser absorption rate is lower, generally in 30-40% left and right.Easily there is the defects such as crackle, shrinkage porosite, shrinkage cavity, pore in cladding layer, and the hardness of cladding layer, intensity etc. often can not reach explained hereafter requirement.For example in most self-fluxing alloy powders, the content of boron and silicon is higher, make some in laser cladding process be mingled with as borosilicate cannot be smoothly from emersion in the molten bath of rapid solidification, cause laser cladding layer cracking sensitivity large, when laser cladding layer hardness is high, cracking phenomena is particularly evident.Therefore, develop a kind of cermet powder that is specifically designed to the cladding of continous way optical-fiber laser very urgent.
Summary of the invention
Technical problem to be solved by this invention is: the invention provides a kind of nickel based metal ceramal powder that is exclusively used in the cladding of continous way optical-fiber laser, this nickel based metal ceramal powder is in the process of continous way optical-fiber laser cladding, not only can greatly improve the absorptivity of metalwork to laser, and it is fine and close to form one deck internal organizational structure on its surface, the defect cladding layers such as flawless, shrinkage cavity, bubble, in the service life of the metalwork greatly increasing, reduced production cost.
For solving the problems of the technologies described above, technical scheme of the present invention is: the nickel based metal ceramal powder that is exclusively used in the cladding of continous way optical-fiber laser, by weight percentage, comprise 12-19% alundum (Al2O3), 6-12% lanthana, 12-16% titanium dioxide, 3-7% calcirm-fluoride, 2-6% cerium oxide, surplus is Ni-based.
Above-mentioned nickel based metal ceramal powder comprises 16% alundum (Al2O3), 9% lanthana, and 13% titanium dioxide, 5% calcirm-fluoride, 4% cerium oxide, surplus is Ni-based.
The nickel based metal ceramal powder effect that is exclusively used in the cladding of continous way optical-fiber laser of the present invention is as follows:
Nickel (Ni) element: as cermet substrate, thorough melting during cladding, together forms laser molten pool with the base material of molten condition is uniformly distributed after coagulation for other elements or compound and becomes cladding layer, to increase cladding layer hardness in molten bath.
Alundum (Al2O3) (Al
2o
3): belong to metal ceramic powder, as strengthening particulate, be present in cladding layer, can greatly improve cladding layer hardness and intensity, can reduce the sensitiveness of cladding layer cracking, improve the absorptivity of laser.
Lanthana (La
2o
3): can crystal grain thinning, in the process of laser melting coating, increase the compactness of its interior tissue combination, improve the quality of cladding layer.
Titanium dioxide (TiO
2): be conducive to improve the absorptivity of nickel based metal alloy powder of the present invention to laser, thereby can reduce the power stage of laser instrument, improve the utilization rate of the energy.
Calcirm-fluoride (CaF
2): as adding material,, there is the defects such as fire check, shrinkage cavity and porosity after preventing from solidifying in the internal stress while solidifying for reducing cladding layer, improves the compactness of metal inside tissue.
Cerium oxide (Ce0
2): can improve the absorptivity of metal alloy powders to laser, increase the utilization rate of the energy.
The invention has the beneficial effects as follows:
1. nickel based metal ceramal powder of the present invention, in the cladding of continous way optical-fiber laser, nickel-base alloy powder foot couple laser has higher absorptivity, has improved the utilization rate of the energy, has saved production cost;
2. nickel based metal ceramal powder of the present invention can reduce powder coefficient of thermal expansion in cladding process, reduces cracking sensitivity, improves quality of cladding layer.
3. pass through nickel based metal ceramal powder of the present invention, the cladding layer dense internal organization of formation, the defects such as flawless, shrinkage porosite, pore, and there is the performances such as high rigidity, intensity, toughness and highly corrosion resistant.
