Abstract

Intermetallic thin films find application as protective high-temperature oxidation resistant coatings on gas turbine and aerospace components. The Intermetallic compound $Ni_3Al$ has potential towards application as protective coating and as well as bond coat between thermal barrier coating and superalloy engine components. Laser ablation is a powerful technique of depositing thin films of refractory materials. Due to the fast nature of the deposition process, the deposited matter experiences conditions far away from equilibrium. It is therefore important to study the phase evolution in laser ablation deposited $Ni_3Al$ film. In the present paper the phase formation in vapour deposited film and phase evolution during heating will be discussed.
