Description
Require right of priority
The application requires the U.S. Provisional Patent Application No.60/871 of submission on December 21st, 2006, the novel patent application No.11/954 of U.S. utility that on December 12nd, 270 and 2007 submitted to, 909 rights and interests.
Technical field
The present invention relates in general to hard-face overlaying welding, and particularly the high wear metal matrix composite hard-face overlaying welding material of improvement for example is used for subsurface tool.
Background technology
In design with make in the earth-boring bits, long-standing way is: apply wear-resisting hard-face overlaying welding material through frayed surface to these drill bits during drilling operation.In the earth-boring bits of rolling cone drill bit type, these surfaces comprise the tooth of milling or steel-tooth type drill bit, the gage surface of rolling cone drill bit (gage surface) and comprise the palm root edge (shirttail) of the drill bit palm of drill body.
In the past, these hard-face overlaying welding compositions comprise the IVB, the VB that are in the matrix metal that iron, cobalt or nickel and their alloys and mixts constitute and the carbide of group vib element usually.Adopt oxy-acetylene or atom hydrogen torch, the part surface and the matrix that will apply hard-face overlaying welding by fusing apply the hard-face overlaying welding thing.Carbide particle is given hard-face overlaying welding material hardness and wear resistance, and matrix metal provides the fracture toughness property of hard-face overlaying welding thing.The hard-face overlaying welding composition must reach enough balances between wear resistance (hardness) and fracture toughness property.Extremely hard and attrition resistant hard-face overlaying welding composition may lack fracture toughness property, causes that the hard-face overlaying welding thing ftractures too early and peels off.On the contrary, have enough fracture toughness propertyes but hard-face overlaying welding thing with not enough hardness and wear resistance is subjected to corroding too early and can not being used for its purpose.
The several factors influence is used for the suitability of the hard-face overlaying welding composition of specific end use.These factors comprise the chemical constitution and the physical structure of the carbide that uses in the said composition, the microstructure of matrix metal or alloy and chemical constitution, and carbide material is each other and the relative proportion between carbide material and matrix metal or the alloy.
The early stage progress of the hard-face overlaying welding Composition Aspects that is used for earth-boring bits is disclosed in the common transfer U.S. Patent No. 3,800,891 of White.This patent disclosure in alloy steel matrix, comprise the hard-face overlaying welding composition of cemented tungsten carbide.The agglomerating wolfram varbide comprises and non-carbide material (for example cobalt) binding agent sintering and tungsten carbide crystal grain that keeps together or particle.Cemented tungsten carbide has the fracture toughness property bigger than more conventional cast tungsten carbide, makes the hard-face overlaying welding composition of gained have good fracture toughness property, and does not sacrifice hardness and wear resistance.
The U.S. Patent No. 4,836,307 of Keshavan discloses the particle of the particle that utilizes gluing or cemented tungsten carbide in soft steel matrix and relative little monocrystalline carbonization one tungsten, is referred to as " coarse-grain " wolfram varbide sometimes.It is disclosed to claim that said composition has in the advantage of cemented tungsten carbide such as the U.S. Patent No. 3,800,891, has the advantage of monocrystalline carbonization one tungsten (it is harder than gluing or cemented tungsten carbide), but lower than the fragility of optional cast carbide.
The United States Patent (USP) 5,089,182 of Findeisen discloses the method for preparing the cast carbide pill, and described pill is roughly sphere and has the machinery and the metallurgical properties of improvement with respect to the carbide pill of prior art.These cast pellets are not definite in spherical, but enough symmetrical, make that the unrelieved stress in the pill is minimized.Equally, the spheric shape that is roughly of these pills has been eliminated the corner angle that exist in the conventional crushed particles, sharp edge and horn shape projection, and described corner angle, sharp edge and horn shape projection can improve the unrelieved stress in the particle and be tending towards fusing when the hard-face overlaying welding composition is put on the surface.
The U.S. Patent No. 5,663,512 of Schader discloses the hard-face overlaying welding composition of the spherical tungsten carbide particulate (with WC/W2C eutectic form) that comprises a certain amount of spherical sintered tungsten carbide particulate and a certain amount of casting.During use, some fusings of sintered, spherical carbide granules take place, it is separated out to metal matrix and coats spherical WC/W2C particulate.Although said composition provides well balanced between hardness and fracture toughness property, drill bit has toughness, ductility and the shock strength of steel and the hardness and the wear resistance of wolfram varbide on the outer surface or other hard metal, but there is not the problem of prior art steel body or steel tooth bit in expectation.
Summary of the invention
The system of the high abrasive wear metal matrix composite hard-face overlaying welding material that is used for subsurface tool, the embodiment of method and apparatus are disclosed.Hard-face overlaying welding material can comprise: have high rigidity relatively than the matrix of soft material amorphous nano clad steel alloy for example, and one or more hard constituent materialss.Hard constituent materials can comprise the annexing ingredient of cemented tungsten carbide (for example WC/Co), monocrystalline WC, compound crystal or polycrystalline WC and spherical cast tungsten carbide (for example eutectic of WC/W2C).As an alternative, can use the matrix than soft material, hard constituent materials and broken cast tungsten carbide.
