Purpose: In this paper the oxidation resistance of palladium modified aluminide coatings deposited by CVD method on nickel-based superalloy was evaluated. Design/methodology/approach: Palladium coatings 3 and 7 μm thick were deposited by the electroplating process. The heat treatment of electroplating coatings at the temperature 1050 °C for 2 h under argon atmosphere was performed. Low activity CVD...
Purpose: Research and Development Laboratory for Aerospace Materials in Rzeszow University of Technology is the place where production of single crystal nickel base superalloys has been proved technically feasible. This paper presents the method of manufacturing the single crystal superalloys turbine blades and the prospective developments of the enterprise. Design/methodology/approach: Turbine blades...
Purpose: The aim of this work is to determine physical and chemical properties of cobalt aluminate (CoAl2O4) modifiers produced by different companies and the influence of different types of modifiers on the grain size, the microstructure and mechanical properties of high temperature creep resisting superalloy René 77. Design/methodology/approach: The first stage of the research work took over the...
