Self-propagating high-temperature synthesis of IrAl and its application to coating process

Abstract An IrAl intermetallic compound was fabricated by a self-propagating high-temperature synthesis (SHS) process. Single phase IrAl pellets were produced; however, the IrAl coatings produced, with the aid of numerical simulations, contained unreacted Ir and was found to have poor adhesion. Nevertheless, this study confirmed that IrAl coatings can be obtained using the SHS process.
