  1. 1. Erosion - Corrosion Resistance and Adhesion of Laser and Thermally Deposited Coatings in Fluidised Beds

    Author : Anders Hjörnhede; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; coating; fluidised bed; HVOF; laser cladding; CFB; FBC; adhesion testing; PFBC; thermal spraying; arc spray; erosion - corrosion; acoustic emission;

    Abstract : High temperature erosion - corrosion is the major source for degradation of components such as heat exchangers, tubes, cyclones and water walls used in Fluidised Bed Combustion (FBC) plants. By coating the exposed components with a protective material, the degradation rate can be decreased. READ MORE

  2. 2. Adhesion strength of HVOF sprayed Inconel 718 coatings

    Author : Christophe Lyphout; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adhesion Strength; Residual Stress; Inconel 718; Thermal spray; Finite Element Method; HVOF; High Velocity Oxy-Fuel;

    Abstract : Thermal spray technology in general is nowadays recognized as an industrial process, mature enough to apply coatings on different substrate materials that protect parts against wear, corrosion, heat, or combinations of these. The quality demands on coating homogeneity and adhesion strength are, nowhere more than in the automotive and aeronautic industries, continuously increasing. READ MORE

  3. 3. Adhesion and Residual Stress Characterization of HVOF Sprayed Inconel 718 Coatings

  4. 4. Microstructure and oxidation behavior of High Velocity Oxy-Fuel spray deposited Ti2AlC coatings

    Author : Marie Sonestedt; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; coatings; High Velocity Oxy-Fuel HVOF ; Ti2AlC; oxidation; microstructure; SEM; TEM;

    Abstract : Ti2AlC is one of the ternary carbides in the MAX phase group of materials. This group of materials have a unique combination of ceramic and metallic properties, such as machinability, high thermal conductivity, low density and oxidation resistance. READ MORE

  5. 5. Oxidation and Corrosion of New MCrAlX Coatings : Modelling and Experiments

    Author : Kang Yuan; Ru Lin Peng; Xin-Hai Li; Sten Johansson; Yan-Dong Wang; Robert Vaβen; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : MCrAlY coatings (“M” for Ni and/or Co) are widely used for the protection of superalloy components operated at high temperatures such as in the hot sections of gas turbines. The exposure to high temperature can cause coating degradation due to oxidation or hot corrosion at the coating surface. READ MORE
