Opis

Metal-based thermal barrier coatings (MBTBCs) have §been produced, using Induction plasma spraying (IPS) §of nanostructured alloy powders. Important advances §have been made over recent years to ceramic-based §thermal barrier coatings (TBCs) for internal §combustion engines application, but they are not yet §applied in mass production situations. §Besides the important economic considerations, the §reliability of ceramic TBCs is also an issue, due to §the difficulty of predicting in-service lifetime. §Through engineering of the nano/amorphous structure §of MBTBCs, their thermal conductivity can be made as §low as those of ceramic-based TBCs. The thermal §conductivity of MBTBCs was found to be §as low as 1.99W/m/K. Thermal expansion coefficient §(TEC) of MBTBCs was 13E-6/K, which is close to the §TEC of cast iron and thus, closer to the TEC values §of aluminium alloys than are conventional TBCs. §Fracture toughness of MBTBCs has also been assessed §by use of Vickers hardness tests, with a 500g load §for 15s, and there are no measurable crack §developments around indented areas on MBTBCs §tested.
