Description
Technical field
The invention belongs to the welding processing technical field, particularly relate to a kind of nickel-base spraying smelting alloy powder.
Background technology
Spray fusing claims surfacing again, mainly is divided into two kinds of technologies of flame spray remolten and plasma spraying, and used spraying smelting alloy powder end is a self-fluxing powder, and at present the self-fluxing powder that uses mainly contains three kinds in fe-based alloy powder, nickel-base alloy powder and cobalt-base alloys powder.Wherein, the granularity of the used self-fluxing powder of flame spray remolten is generally-150 orders～+ 320 orders (two-step method spray fusing) and-320 orders (one-step method spray fusing); Two-step method spray fusing and one-step method spray fusing are meant the spraying smelting alloy powder use, and the two-step method spray fusing refers to that first dusty spray to requiring size, carries out remelting again, and it is thick that used powder is wanted; The one-step method spray fusing carries out remelting after referring to spray certain thickness powder immediately, carries out remelting again immediately after spraying certain thickness powder again, and until requiring size, i.e. spraying and remelting hockets until requiring size, and used powder is wanted carefully; The granularity of the used self-fluxing powder of plasma spraying is generally-60 orders～+ 150 orders.The fusing point of self-fluxing powder is low, is generally 950～1400 ℃, good fluidity; the deoxidation slag making voluntarily of element in melting process in the closing gold is protected alloy, behind the alloy graining; in alloy, can form the dispersion-strengtherning phase of high rigidity, to improve the intensity and the hardness of alloy.Generally all contain Si and B element in the self-fluxing powder, its effect is: (1) reduces the fusing point of alloy, and makes the temperature range that broad is arranged between the solid phase of alloy and the liquid phase; (2) carry out deoxidation and reduction and slag making; (3) improve hardness of alloy, Si mainly plays the solution strengthening effect, and B mainly plays dispersion-strengthened action.
Nickel-base spraying smelting alloy powder is mainly used the workplace below 600 ℃, be applicable to the preventative surface treatment or the surface reparation of steel-iron components, and each easily plants part of wearing and tearing, the manufacturing and the reparation of the part of working in corrosive mediums such as acid, alkali.Existing nickel-base spraying smelting alloy powder, by first mechanical industry ministerial standard (JB-3168-82) the subordinate list 1-2 " oxy-acetylene flame surfacing alloy powder chemical composition and physical property " of the People's Republic of China (PRC), the oxy-acetylene flame spray fusing only contains C, Fe, Si, B, Cr, Ni with nickel-base alloy powder, the solid solution strengthened alloy element mainly is Cr behind the spray fusing, and single-phase solid solution strengthening effect is bad; Dispersion-strengtherning mainly is the boride of Ni and Cr mutually, and the hardening constituent type is less, and especially high temperature abrasion resistance is not enough to cause wearability, and its range of application is restricted.By first mechanical industry ministerial standard (JB-3168-82) the subordinate list 1-1 " plasma spray welding powdered alloy chemical composition and physical property " of the People's Republic of China (PRC), except that C, Fe, Si, B, Cr, Ni element, contain 0.50～0.60%Al in the F12-37 trade mark of plasma spraying with nickel-base alloy powder, contain 2.00～3.00%Cu and 2.00～4.00%Mo in the F12-54 trade mark, the solid solution strengthened alloy element mainly is Cr and Mo behind the spray fusing, intensified element is still less, and solid solution strengthening effect is good inadequately; Al is γ ' (Ni
3Al) the main forming element of phase, by the disperse distribution reinforced alloys of boride in matrix of γ ' and Ni, Cr, the element kind that alloy forms the precipitation strength phase is few, and wearability especially high temperature abrasion resistance is not enough.Therefore be necessary on existing basic element basis, to add multiple element to improve the wearability of spraying smelting alloy powder, especially high temperature abrasion resistance.Nb, Ti and Ni can form Ni
3(AlTi), Ni
3Ti, Ni
xNb, the precipitation strength phase can be passed through their disperse distribution reinforced alloys in matrix.V, W can dissolve into γ ' mutually in, thereby strengthen with stable γ ' mutually, V, Nb, Ti, W easily form strong carbide, the high-temperature stability of these carbide is good, W, V, Ti have stronger solution strengthening ability, and these factors improve the intensity of spray fusing alloy, and wearability is good.So far, do not see that the report that adds V, Nb, Ti, W in nickel-base spraying smelting alloy powder is arranged.
Summary of the invention
At the shortcoming that wear no resistance of existing spray fusing with nickel-base alloy powder, technical problem underlying solved by the invention provides a kind of nickel-base spraying smelting alloy powder with better wearability and preparation method thereof.
Nickel-base spraying smelting alloy powder provided by the invention also contains following ingredients: C:0.40～1.2%, Si:3.5～5.0%, B:2.5～4.5%, Cr:13.0～20.0%, Fe by weight percentage except containing nickel and impurity: V:0.5～1.8%≤17.0%.
