  • The optimisation of bondcoat oxides for improved thermal barrier coating adhesion 
    Fisher, Gary Anthony (1998-03)
    Superalloys used for the critical hot sections of modem aero-gas turbines . are designed primarily to exhibit good creep and fatigue resistance, coupled with toughness and microstructural stability. However, an optimum ...
  • Performances of air plasma sprayed thermal barrier coatings for industrial gas turbines 
    Seraffon, Maud (Cranfield University, 2012)
    Future industrial gas turbines will be required to operate at higher temperatures to increase operating efficiencies and will be subjected to more frequent thermal cycles. The temperatures that the substrates of components ...
  • Phosphor thermometry in an EB-PVD TBC 
    Steenbakker, Remy (Cranfield University, 2008-01)
    Thermal Barrier Coatings (TBCs) are used to reduce the actual working temperature of the high pressure turbine blade surface. Knowing the temperature across a TBC and at the interface with the thermally grown oxide (TGO) ...
  • Predicting hot corrosion rates under coal fired combined cycle power plant conditions 
    Smith, P. J. (Cranfield University, 1994-04)
    Type 11 hot corrosion has been identified as a major life limiting factor of gas turbine components in the topping cycle of coal fired combined cycle power plant. Impurities in the coal combustion gases provide the ...
  • Pressure effects on the hot-salt stress-corrosion cracking of titanium alloys 
    Chevrot, Thierry (Cranfield University, 1994-03)
    Benefiting from good specific mechanical properties, exceptional oxidation resistance, and high temperature capability, Titanium Alloys are used in Gas Turbine Engines, especially in the early stages of the compressor. ...
  • Reactive plasma spraying 
    Al-Sabouni, Omar (Cranfield University, 1999)
    Reactive Plasma Spraying (RPS) with a hydrocarbon gas has been studied as a method to improve the mechanical properties of a commercially available 80: 20 nickel-chromium alloy, and subsequently as a method to reduce ...
  • Steam oxidation of advanced high temperature resistant alloys for ultra-supercritical applications 
    Lukaszewicz, Mikolaj (Cranfield University, 2012-06)
    Steam oxidation of heat exchanger tubing is of growing interest as increasing the efficiencies of conventional pulverised fuel fired power plants requires higher steam temperatures and pressures. These new, more severe ...
  • The Structure and Stability of High Temperature Intermetallic Phases for Application within Coating Systems 
    Roberts, Tracey (Cranfield University, 2009-11)
    The reduction of noise and emissions is becoming increasingly important in civil aircraft jet engines as well as requirements for reduced fuel consumption and improved efficiency. This has resulted in the drive towards ...
  • Study of hot corrosion of single crystal superalloys and platinum-aluminide coatings 
    Encinas-Oropesa, Adriana (Cranfield University, 2005-10)
    At the present time, combined cycle systems for power generation (e. g. IGCC), offer increased efficiency of power generation and lower environmental emissions, specifically C02, SOxg, and NO,,, as well as being adaptable ...
  • TERA for Rotating Equipment Selection 
    Khan, Raja S. R. (Cranfield University, 2012-01)
    This thesis looks at creating a multidisciplinary simulation tool for rotating plant equipment selection, specifically gas turbines, for the liquefaction of natural gas (LNG). This is a collaborative project between Shell ...
  • TiB2 ceramic and DLC Multilayered PVD coatings 
    Santos da Silva Cruz, Ricardo Manuel (Cranfield University, 2007)
    Titanium diboride (TiB2) has been investigated as a potential candidate for several industrial applications, such as: cutting tools, electric devices, wear parts and many more fields of application. The main drawback of ...
