Description
Technical field
The present invention relates to the technology of preparation high temperature protection compound coating on the superalloy matrix, specifically a kind of preparation method of composite coating that contains diffusion barrier generated in situ, it utilizes sedimentary in advance multilayer film, in conjunction with relevant heat treating regime, prepare and a kind ofly can under hot conditions, suppress the coating element and spread, thereby improve the coating compound coating in work-ing life to matrix.
Background technology
As the superalloy of aero engine turbine blades, generally include Ni-based and cobalt base alloy.Under the usage condition, except will having excellent high temperature and ambient temperature mechanical properties, superalloy also should have good resistance of oxidation.At present, a kind of terms of settlement is at its surface-coated high-temperature protection coating, utilizes the antioxidant property of coating, and protection superalloy matrix avoids taking place high temperature oxidation 1000 ℃ of high temperature section up and down.MCrAlY coating (M=Ni, Co or NiCo) and aluminide diffusion coating are present two kinds of the most frequently used high-temperature protection coatings.In fact, comprehensive these two kinds of coatings, forming a kind of is bottom with the MCrAlY coating, and the AlSiY coating is that the compound coating of top layer has better high temperature oxidation resistance, and this point has obtained proof.
The preparation method of MCrAlY coating comprises cold spraying, plasma spraying (APS, VPS and LPPS), hypersonic flame spraying (HVOF), magnetron sputtering (MS) and arc ion plating (AIP) etc.The preparation method of aluminide diffusion coating mainly contains solid phase aluminising, chemical vapor deposition (CVD) etc.Arc ion plating prepares coating, because it is low to have higher sedimentation rate, the densification of bonding strength, and coating preferably, porosity, is one of ideal style of preparation MCrAlY coating and aluminide coating.
Along with the development of aeronautical technology, the use temperature of blade improves constantly, and is also more and more higher to traditional high-temperature protection coating requirement.Especially the mutual diffusion between principal element and the matrix element in the coating under the high temperature; not only continuously consume the aluminium and the chromium of protectiveness in the coating; thereby make coating quicken to degenerate; and matrix alloy is at a large amount of refractory metal element of this process also loss; make original solution strengthening effect weaken, reduced the mechanical property of matrix.Therefore, improve the use temperature of protective coating, the problem that must solve is exactly this mutual diffusion behavior that how to reduce between coating and the matrix, thereby suppresses the degeneration of coating and matrix, the usage life-span of improving blade.Domestic and international research person all wishes by adding a diffusion impervious layer between coating and matrix, stoping or to delay the diffusion of element by this layer, and obtained a large amount of achievements.Wherein, be included between MCrAlY coating and the matrix to add and have certain thickness, a fine and close blocking layer, as Re, Ta, W, Mo layer by what one or more refractory elements were formed.This refractory element layer can at high temperature keep a very long time, greatly reduces the mutual diffusion between coating and the matrix.
Regrettably, the general difficulty of the diffusion impervious layer of being made up of refractory element is all on preparation technology and cost.Utilize pure metal or alloy target material extremely high, and target utilization is low by the price that physical method (as PVD) prepares this diffusion impervious layer; Also have the scholar to deposit coating by galvanized mode, obtained good effect, and electroplating technology is compared to other deposition methods, manufacturing cost also greatly reduces.But because sedimentary coating is thicker, make that the bonding force of coating and matrix is relatively poor, the raw materials cost of Shi Yonging also can not be underestimated simultaneously.So the coating process of change refractory metal reduces thickness of coating, form substitutable layer by other elements and refractory metal acting in conjunction with equal effect, be the direction that investigators make great efforts always.
