Oxidation resistance of plasma sprayed thermal barrier coatings

Oxidation resistance of plasma sprayed thermal barrier coatings

With the development of aviation industry, the inlet temperature and efficiency of turbine engine gas are constantly improving, but the existing superalloy and cooling technology can not meet this demand. Therefore, the application of plasma sprayed thermal barrier coating on the surface of superalloy is particularly important, and thermal barrier coating has a long history of working at high temperature. Antioxidant capacity is an important index to evaluate the properties of plasma sprayed thermal barrier coatings. The thermodynamic and kinetic analysis of high temperature oxidation behavior of plasma sprayed thermal barrier coatings was carried out by using the method of weighing and oxide layer thickness. The composition distribution and structure changes of the samples were studied by means of X-ray diffraction and electron probe. The oxidation mechanism of thermal barrier coating was discussed based on the experimental results. The static oxidation performance of ZrO2 thermal barrier coating prepared by atmospheric plasma machine spraying was tested by using MgO and Y2O3 as stabilizers. It was found that the static oxidation kinetics of the two thermal barrier coatings followed a parabolic rule, and the porosity decreased with the increase of oxidation temperature, while the monocline content increased. Although the MgO content is higher than that of Y2O3, the Y2O3-stabilized ZrO2 thermal barrier coating has better thermal stability. However, in the Y2O3 stabilized ZrO2 thermal barrier coating, Al element is uniformly distributed on the transition layer and has good oxidation resistance. The Y2O3-ZrO2/NiCoCrAlY composite thermal barrier coating was prepared by low pressure plasma spraying technology, and the static oxidation test was carried out at 800-1000℃. The thermal barrier coating has good high temperature oxidation resistance by spraying the adhesive layer by low pressure plasma processor. Moreover, after the sample is oxidized for a long time at a high temperature, the aluminum element in the binder layer will diffuse to the interface between the ceramic layer and the binder layer, forming a uniform and dense double alumina film, which can protect the matrix more effectively. Research on three kinds of high temperature oxidation behavior of thermal barrier coating showed that plasma oxidation process of thermal barrier coating can be divided into oxygen absorption, diffusion of oxygen in the ceramic layer, selective oxidation Al2O3 film, film growth, thick film and thick film destroyed six stages, including the distribution of aluminum directly affect the growth of the protective film and mature, will affect the oxidation resistance of the coating.

Sheet Plasma Surface Processor to promote the adhesion of coating materials

Sheet Plasma Surface Processor to promote the adhesion of coating materials

The sheet plasma surface processor consists of a plasma generator, a dielectric electrode tube system and a discharge platform. The high voltage and high frequency energy generated by the plasma generator generates low temperature plasma in the glow discharge activated and controlled by the electrode tube, and the plasma is sprayed on the workpiece surface. When the plasma meets the surface of the object to be treated, chemical reactions and physical changes occur, the surface is cleaned, and hydrocarbon contaminants such as oils and auxiliary additives are removed. Change the structure of molecular chains on the surface according to the composition of the material. The free radicals such as oxygen free radicals and hydroxyl groups were established to promote the adhesion of various coating materials, and were optimized in the application of adhesion and coatings. With the same effect, a very thin coating surface with high tension can be obtained by plasma surface treatment, without the need for any strong components such as other mechanical and chemical treatments to increase adhesion. Many physical and chemical changes have taken place on the surface of the material sheet by means of plasma surface treatment, such as etching and roughening, forming a dense crosslinking layer, or introducing polar groups containing oxygen to improve hydrophilicity, adhesion, dyeability, biocompatibility and electrical properties, respectively. The surface morphology of the material is significantly changed by the treatment of the material surface under the appropriate process conditions, and the introduction of a variety of oxygen-containing groups makes the surface change from non-polar and difficult to adhere to a certain polarity, easy to adhere to and hydrophilic, which is conducive to bonding, coating and printing.

Plasma surface treatment of polymer materials surface applications

Plasma surface treatment of polymer materials surface applications

Most organic gases are polymerized and deposited on the solid surface under the action of low-temperature plasma surface treatment to form continuous, uniform, pinhole-free ultrathin films, which can be used as protective materials, heat insulation materials, liquid-gas separation films and laser guided films, etc., and are widely used in optical, electronic, medical and other fields. Poly (methyl methacrylate) or polycarbonate plastic plasma polymer can be used to produce inexpensive, high-quality and easy to process optical lenses, but the surface hardness of the lens is too low, easy to produce scratches. Plasma deposition with fluorine or silicone monomer on the surface of the lens at low temperature can improve the anti-scratch performance and reflectivity of the lens. Plasma chemical vapor deposition technology has been applied to plastic window glass, automobile blinds, car lights and halogen sky lamps. Plasma polymer films have many properties that allow the same substrate to be used in many fields. The method of chemical vapor deposition for diamond carbon wear resistant coating is to introduce carbon gas into plasma. This plasma has the characteristics of chemical resistance, no pinhole, no leakage and so on, which can prevent various chemical agents from corroding the substrate. You can also apply antifriction paint to windshield wipers or a low friction paint to computer disks to reduce head collisions. Plasma polyethylene film deposited on the surface of silicone rubber can significantly reduce the oxygen transmission coefficient of silicone rubber. The reverse osmosis membrane was prepared with nitrogen-containing monomer, and the salt resistance of the membrane reached 98%. In general, polymer microcapsules are used for biological sustained-release drugs. Reverse osmosis film can be formed on the surface of microcapsules by plasma polymerization technology. The results show that the discharge power and other factors have a great influence on the resistance of plasma polymer films when they are used as sensor elements. After treated with different vinyl monomers and AR glow discharge, the hydrophobicity and dyeing properties of the fabric were improved in a very short time.
