Description
Technical field
The present invention relates to and the invention belongs to field of surface modification, relate to a kind of method preparing zirconium white and nickel base powder composite coating based on plasma melting coating technique.
Background technology
Traditional process for modifying surface mainly comprises: built-up welding, cladding, thermospray and Brush Electroplating Technique etc., different with other process for modifying surface, the advantage that plasma melting coating technique has it exclusive as a kind of brand-new process for modifying surface, this technology powdered ingredients controllability is good, being evenly distributed of cladding process interalloy powder, microstructure of surface cladding layer densification chops up little, tissue defects is less, high with substrate combinating strength, in addition, its technological process is simple, pollute few, cost is low, equipment cost is only 1/5 of laser melting coating, there are some researches show, plasma cladding production efficiency is about the 6-10 of laser melting coating doubly, powder using efficiency is 2-3 times of laser melting coating, not high to operating environment requirements, both may be used for the surface modification of traditional material, promote the over-all properties of material, may be used for again the repair of surface failure part, make it at electric power, coal, metallurgical, the numerous areas such as machinery have broad application prospects.
The interpolation of plasma cladding powder mainly contains two kinds of modes: fore-put powder method and synchronous powder feeding system method.Fore-put powder method mixes with powder with organic solvent, and furnishing is thick, is coated on matrix fusion, under beam-plasma Source, fore-put powder is melted, form metallurgical coating after cooling at matrix surface after drying.Synchronous powder feeding system is sent in molten bath by powder feeding channel by cladding powder by powder feeder, and powder feeding and cladding synchronously carry out.In two kinds of methods, the efficiency of synchronous powder feeding system is higher, and preset method is difficult to accomplish that coating thickness is even, and binding agent volatilization easily causes powder to fly sword, even forms pore, affects coating performance.
Plasma cladding powder mainly can be divided into self-fluxing alloyed powder and composite powder two class.Self-fluxing alloyed powder is the alloy that self can play flux effect, and namely in cladding process, itself have deoxidation and slag making function, boron and silicon are used for herein.Main self-fluxing alloyed powder has iron-based, cobalt-based, Ni-based three major types both at home and abroad at present.Iron-base self-fluxing alloy divides two types: one is austenitic stainless steel self-melting alloy.Its crucible zone tissue is made up of austenite and multiple carbide, boride etc.Cladding layer has wear-resisting, wear-corrosion resistance preferably, more excellent than austenitic stainless steel (1Cr18Ni9Ti, 2Cr13) wear resisting property, and processing characteristics is better.Another kind is high carbon and chromium type self-melting alloy, containing higher carbon and chromium, through eutectic pig iron, has more carbide, boride in microstructure of surface cladding layer, and hardness, wear resistance are fine, and corrosion-resistant, but processing characteristics is poor; Ni-based self-fluxing alloy end can be divided into Ni-B-Si and Ni-Cr-B-Si two series: one is Ni-B-Si alloy, and the tissue of cladding layer is made up of Ni-Si sosoloid (Y phase) and the various boride of Dispersed precipitate (Y ' phase) and Y mono-Y ' eutectic phase.This alloy rigidity is lower, good toughness, and high temperature resistance, wear-resisting, corrosion resistance and good, be easy to mechanical workout.Another kind is Ni-Cr-B-Si self-melting alloy, and the metallographic structure of its cladding layer is more complicated.Be made up of the hard phase such as carbide, the carbide of boron, the carbide of tungsten of the Y ' phases such as nickel one chromium solid solution, the boride of nickel, the boride of chromium and chromium.This kind of alloy still has higher hardness 500 DEG C time, wear-resisting, corrosion resisting property good, is powdered material conventional when adopting laser melting and coating process; Cobalt-based self-fluxing alloyed powder it be basal component with Co, add Cr, the alloy that C and Mo etc. are elementary composition.Cr element can be solid-solubilized in the face-centered cubic crystal of Co, had both played solid solution effect, and played passivation again to crystal.Improve corrosion resisting property and high temperature oxidation resistance, Cr and C more than needed, B form chromium carbide and chromium boride hard phase, improve alloy rigidity and wear resistance.Cr, Mo, have the adding of elements such as w the function improving wear resistance.Mo, W are solid-solubilized in Co matrix, can make lattice that large distortion occurs, remarkable reinforced alloys matrix, improve hot strength and the red hardness of matrix.Excessive W can also form wolfram varbide hard phase with carbon, improves wear resistance.The microstructure of surface cladding layer of the alloy of cobalt-based is the Y phase sosoloid of Co-Cr, the chromium of disperse educt and the carbide of tungsten and boride.There is the high-performances such as heat-resisting, wear-resisting, corrosion-resistant, resistance to high temperature oxidation.General use temperature more than 600 DEG C still has very high red hardness.
Zirconia ceramics has high-melting-point, low thermal conductivity, high temperature oxidation resisting and high thermal shock performance, zirconic resistance to elevated temperatures is given prominence to, and there is good chemical stability and beautiful and charming wear resistance, its coating is usually in engine hot parts, and zirconium white is used for hot spray coating, apply less in plasma melting coating, the high-temperature behavior of its excellence can be applied completely in cladding layer.
Zirconium oxide fibre is a kind of polymorphous ceramic fiber material, and grain-size is at 10-10
2in nanometer range, Fibre diameter 1-50 μm.Zirconium oxide fibre itself is formed by a large amount of zirconia grains packing arrangement, and therefore it is the same with zirconia particles, has three kinds of different crystalline state from room temperature to high temperature.Zirconium oxide fibre has macrofiber and two kinds, staple fibre, and staple length generally can change to centimeter-scale from micron order, and long stapled length is the continuous fibre being greater than 1m.Zirconium oxide fibre inherits the excellent characteristic of zirconia ceramics, high strength, high tenacity, anti-oxidant good, and the tensile strength of fiber at present itself can reach more than 2.6GPa, and maximum operation (service) temperature can reach 2200 DEG C.
Zirconium oxide fibre adds in Ni-based coating and has toughening effect, fiber reinforced mechanism mainly comprises crackle and bends and deflection, fibre debonding, spike protein gene and fiber bridge joint, wherein fiber bridge joint is fiber reinforced main mechanism, when crack propagation is to fiber place, crackle can not continue expansion through fiber, and fiber link crackle both sides, play function served as bridge and hinder crack propagation, thus in breaking-down process, more energy is absorbed, the toughness that namely realization place is higher.Due to the rapid cooling feature of self, hardness, the wear resistance of plasma melting coating are enough high, but its toughness is poor, the fiber reinforced existing application in other directions.
