Description
Technical field
The present invention relates to a kind of alloy material, specifically a kind of wear-resistant overlay welding alloy material of anti-liquid-solid mixing medium erosive wear.
Background technology
We know that in industrial production, a kind of wear phenomenon of ubiquity: liquid medium (water or other liquid) when carrying solid particle along surface of solids high-speed motion, usually causes heavy wear to the surface of solids, and academia is referred to as erosive wear.For example: the inefficacy of ore dressing, mining or dredging plants such as cyclone, slush pump, Dredge pump, mainly caused by erosive wear.
Liquid-solid mixture is common in industrial production to the erosive wear of equipment, and greatly destructive.At present, the destruction that cause equipment for the alleviation erosive wear home and abroad, in the selection of manufactured materials: the one, adopt the casting high-chromium alloy, most of slush pump, Dredge pump are formed by the high-chromium alloy casting.High-chromium alloy is the comparatively general high-abrasive material of a kind of application, have the characteristics of high abrasion resistance, but casting technique is strict, and qualified casting is low, the manufacturing cost height.Moreover, the monoblock cast high-chromium alloy must be taken into account machinability and tough, plasticity simultaneously, generally gets hypoeutectic structure, can not give full play to the anti-wear performance of high-chromium alloy.In addition, the hard hardening constituent of high-chromium alloy is the carbide of chromium (Cr7C3 or Cr23C6 etc.), and its microhardness generally between HV1000～1300, can't satisfy higher wearability requirement as the wear-resisting skeleton in the antifriction alloy sometimes.The 2nd, adopt nonmetallic composite, external production heavymedia separation cyclone selects for use nonmetallic composite to make liner mostly.Domestic research and application facet at nonmetallic composite also lag far behind industrially developed country at present, so homemade cyclone, and service life is still undesirable.
In addition, the applicant's patent of invention 011352310 has proposed a kind of " high temperature and abrasive-particle wear resistant build-up welding alloy material ", be mainly the high carbon and chromium resurfacing welding material, utilize the metal carbon-boron compound has in the alloy high rigidity and wear-resistant grain polishing machine and anti-capacity of decomposition, improve the wear-resistant grain polishing machine under the hot conditions.But, up to now, also do not have can ripe anti-liquid-solid mixing medium erosive wear of using wear-resistant overlay welding alloy material.
Summary of the invention
Technical problem to be solved by this invention is to overcome above-mentioned the deficiencies in the prior art, a kind of macrohardness height is provided, the matrix phase hardness of alloy microstructure is moderate, tough, plasticity is good, with the complicated metal boride of high rigidity is main hard phase, hard mutually evenly, disperse be distributed in matrix mutually in, and combine firmly with it, have the wear-resistant overlay welding alloy material of anti-liquid-solid mixing medium erosive wear and abrasive wear behavior.
The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of wear-resistant overlay welding alloy material, it is characterized in that alloy specifically forms content (weight %) and be: W 9-22, Nb 4-13, V 6-12, Mo 2-5, Cr 1.5-5, B 4-7, rare earth 0.28-1.0, surplus are Fe.
The composition content (weight %) that the present invention optimizes is: W 10-15, Nb 5-11, V 6-10, Mo 2-5, Cr 1.5-4, B 4-6, rare earth 0.28-1.0, surplus are Fe.The preferred rare earth cerium of rare earth Ce compound, content (weight %) is 0.5-0.7.
The present invention is the hard hardening constituent with the heavy metal boride, against existing technologies, has a large amount of baroque borides in deposited metal of the present invention.The hardness of these borides is higher than the carbide of metal of the same race, and its microhardness is all between HV1700～2800.A large amount of metal boride hard phase disperses and the matrix that is evenly distributed in alloy mutually among, when abrasive particle wore and tore to its surface, boride played wear-resisting skeleton function in alloy, and alloy substrate is produced the shade protective effect mutually.Abrasive particle is big more with hard difference of hardness mutually, and the protection effect is obvious more.Rare earth plays inoculation(effect) in the deposited metal crystallization process, make deposited metal crystal grain, and the particularly tiny and even distribution of boride crystal grain all has positive role to improving hardfacing alloy substrate tissue toughness and alloy monolithic wearability.The present invention can make surfacing welding, flux-cored wire, block resurfacing welding material or powder weld deposition material.Can be used for the reparation built-up welding and the manufacturing of cyclone, slush pump, Dredge pump etc., the hardness height, the matrix of microstructure is tough, plasticity is good, has very high anti-liquid-solid mixing medium erosive wear and abrasive wear behavior.
