Description
Technical field
The present invention relates to coating technology, specifically a kind of novel oxidation-inhibited thermal barrier coating (MCrAlY/NiAl/ZrO that is used for the internal combustion turbine hot-end component
2-8Y
2O
3) and the preparation method.
Background technology
On gas turbine component, use thermal barrier coating (Thermal Barrier Coatings is called for short TBCs), can reduce heat, reduce the working temperature of metal parts from the transmission of combustion gas to metal parts.Thermal barrier coating is made up of articulamentum and ceramic topcoats.Articulamentum adopt MCrAlY (M=Ni, Co, Ni+Co) alloy, effect is that the protection base material is at high temperature avoided oxidation and corrosion, realizes the transition of ceramic layer and matrix coefficient of thermal expansion, and provides uneven surface for ceramic layer; The main component of ceramic layer is ZrO
2-Y
2O
3, its effect is to bear high surface temperature, heat shock resistance is wear-resistant.
The oxidation of articulamentum is the major reason that causes thermal barrier coating to lose efficacy.When articulamentum was not oxidized, the stress that thermal expansivity does not match and produces between articulamentum and the ceramic layer can obtain discharging by the suitable expansion and the compression of defective (tiny crack, hole) in the ceramic layer; Under the high temperature articulamentum oxidized after, this expansion and compression be connected layer and ceramic interlayer oxide film (Thermal grown oxide, growth TGO), especially epitaxially grown NiO, Ni (Cr, Al)
2O
4Suppress.In process of cooling, the thermal stresses stack that the growth stress of oxide film and thermal expansivity do not match and produce will cause disbonding to lose efficacy.
Form successive Al at the interface at articulamentum and ceramic layer
2O
3Film can hinder the diffusion of oxygen to articulamentum inside, and the oxidation rate of slowing down articulamentum is improved the oxidation-resistance of articulamentum, improves the work-ing life of thermal barrier coating.In order to promote at the interface Al continuously
2O
3The formation of film, diffusion impervious layer of preparation is an effective means on articulamentum, as Al
2O
3, aluminium compound layer.Since under the high temperature, Al
2O
3The growth of side oxide can cause the appearance of unrelieved stress under the blocking layer, and the therefore increase in time and the rising of temperature also will cause thermal barrier coating to lose efficacy.It is the method that obtains aluminium compound layer usually that calorize, aluminising are handled, but technology is complicated.
Often adopt plasma spraying and electro beam physics vapour deposition (EB-PVD) preparation thermal barrier coating in the prior art.Though the plasma spraying cost is low, coated component is easy to control, have hole, cavity in the coating inevitably and be mingled with, and the coating associativity is poor; Base material temperature height in the spraying process causes that easily coating performance descends in addition.The EB-PVD method can obtain the coating of metallurgical binding and structure atresia.Weak point is: owing under vacuum condition, operate, complex process, the cost height, and sedimentation velocity is low, is not easy the high coating of deposit thickness.
In addition, (application number is: 01133423.1) disclose the method that a kind of detonation flame spraying prepares thermal barrier coating, coating comprises that (composition is ZrO for articulamentum (adopting the MCrAlY alloy system) and ceramic layer to Chinese patent
2-8Y

3) two portions.The preparation method is: adopt explosive spray coating, press articulamentum, the spraying successively of ceramic layer order, obtain thermal barrier coating, and at articulamentum and the middle transition layer that adds of ceramic layer, described transition layer is the multilayered structure of articulamentum and two kinds of compositions of ceramic layer, and wherein: the articulamentum composition 95～5% successively decreases by weight percentage, the ceramic layer composition 5～95% increases progressively proportioning by weight percentage.Though it is not it improves the antioxidant property of articulamentum greatly, also very good.
Summary of the invention
In order to slow down the oxidation rate of articulamentum, improve the oxidation-resistance of articulamentum, the object of the present invention is to provide a kind of cost low, the novel oxidation-inhibited thermal barrier coating (MCrAlY/NiAl/ZrO that coating performance, particularly oxidation-resistance are more excellent
