A XPS Study of Atmospheric Plasma Sprayed TiB2 Coatings

摘要：

　　TiB2 coatings were plasma sprayed in air and were studied by XPS.There are five elements in the top surface of the studied coatings,namely,B,C,N,O and Ti.Oxygen pick-up in the coatings results in formation of oxides of boron and titanium.Nitrogen was shown to exist in N-Ti and O-N-Ti in the coating.Depending on the spraying parameters,mono-boride as well as di-boride was also detected in the studied coatings.With careful peak fitting it was shown that oxygen may exist in the coating as dissolved atomic O in addition to as lattice oxygen in the oxide of boron and titanium.
