Effect of aluminisation characteristics on the microstructure of single phase β-(Ni,Pt)Al coating and the isothermal oxidation behaviour
Source abstract
Abstract
Abstract In the present study, single phase β-(Ni,Pt)Al coatings were prepared in sequence of Pt electroplating and ‘above pack’ aluminisation treatments. Three chief processing factors, including initial Pt thickness, aluminising temperature and time, were selected to investigate their influences on the microstructure of final β-(Ni,Pt)Al coating. Isothermal oxidation behaviour of the coatings with different thickness of Pt was evaluated at 1100 °C in static air. An empirical equation was proposed to show relationship between coating thickness and the three processing parameters. The β-(Ni,Pt)Al coating of 5 μm Pt showed the best oxidation resistance due to superior adhesion of oxide scale.
