Description
Technical field
The present invention relates to alloy field, particularly a kind of stainless valve trim coating nickel-base alloy silk material.
Background technology
Stainless steel, because having excellent solidity to corrosion and mechanical property, is widely used in the manufacture of various acidproof valve and high-temperature high pressure valve in petrochemical complex, reactor and Nuclear power plants.Because medium various in operational process has stronger corrodibility even radioactivity, valve sealing face frequently stands friction, extruding and effect of impact in opening-closing process simultaneously, the trim of valve is easy to be destroyed, and greatly shorten the work-ing life of valve, and the seepage of medium may cause stop work and production, environmental pollution even to cause the generation of serious accident.Therefore, the trim of stainless valve not only requires to have good erosion resistance, and has high hardness, anti-scuffing function and thermal shock resistance and anti-collision performance.
The trim of stainless valve generally adopts the technique of directly carrying out electric arc, flame spurt welding and plasma surfacing high performance alloys layer on valve body to strengthen, alloy raw material used is mainly Fe base, Ni base and Co base self-fluxing alloy powder, these self-fluxing alloy powders are on the basis of matrix element, add Cr, B, Si, C, Mo, elements such as w, the fusing point of powdered alloy is low, self-fluxing nature is good, has the performances such as anti-corrosion, wear-resisting, heat-resisting, anti-oxidant.And the composition of some application scenario to trim strengthening layer has strict requirement, as nuclear valve considers the long-term reliability in valve work-ing life, trim made by normal employing cobalt base alloy, but cobalt can cause secondary emission because of neutron irradiation, and is unfavorable for reactor work; B has very strong neutron absorption capability, easily produces radiation embrittlement and swelling effect.Stellite company develops not containing the Tribaloy T-700 alloy of B, and its composition is (wt.%): Fe≤3.0, Mo:32.5, Cr:15.5, Si:3.4, Co:1.5, C≤0.08, Ni: surplus.
Similar with existing electric arc, flame spurt welding and plasma surfacing technique, laser melting and coating technique is by the cladding material of high power laser light fusing synchronous transport, matrix surface skim melts simultaneously, utilizes the cooling effect of matrix self to obtain with matrix in conjunction with good alloy layer at matrix surface.Laser melting coating has following features and advantage compared with above-mentioned Technology: 1. can realize high-precision cladding and deposit, material use efficiency is high; 2. the thickness of cladding layer and width reliably control by the cladding of multilayer multi-track overlapping; 3. concentration of energy, little to the heat input of matrix, the thinning ratio of cladding layer is low, little with distortion to the heat affecting of matrix; 4. cladding alloy strengthening layer and matrix are metallurgical binding completely, and bonding strength is high; 5. laser cladding process is a rapid solidification, and the tissue of cladding layer is completely fine and close, pore-free, has higher hardness and wear and corrosion behavior.
At present for the main powder feeding method adopting preset cobalt-based and Co-based alloy powder of stainless valve trim laser melting coating strengthening.Powder pre-setting method is generally only suitable at material surface cladding layer of material, and the thickness of cladding layer is restricted, and powder, as laid too thick, is difficult to during cladding ensure the metallurgical binding of coating and matrix and good coating performance; Powder pre-setting method is when carrying out the thicker alloy layer of multilayer cladding preparation, and can not ensure the continuity of cladding process, technique is comparatively loaded down with trivial details; Found through experiments, when laser melting coating Tribaloy T-700 alloy, because the toughness of alloy layer is poor, cladding layer very easily ftractures; In addition, containing Co or B in Tribaloy T-700 alloy and above-mentioned cobalt-based and nickel-base alloy, can not meet some nuclear valve door sealing surface strengthening layer can not strict demand containing B and Co.
Publication number is the nickel-base alloy that the Chinese patent application of CN101368239A discloses a kind of stainless valve trim alloy layer, the composition of this nickel-base alloy and content are: C:1.0-1.5wt%, Cr:17.5-19.5wt%, Mo:7.0-9.0wt%, W:3.5-4.5wt%, Nb:1.5-2.5wt%, Si:2.0-3.0wt%, Ni: surplus.Not containing B and Co in described Co-based alloy powder composition.The alloy of this patent application overcomes the defect of prior art to a certain extent, but it mainly focuses on the melting and coating process performance of alloy, and the over-all properties of alloy self is not still very good.
