Abstract

Recent research efforts have established that Laves phase reinforced gamma titanium aluminides (i.e. γ + Laves) offer significant potential as oxidation resistant coating in high-temperature structural applications and as wear-resistant coatings for cutting tools. In this study, TiAlCr coatings were magnetron sputtered from a Ti-51Al-Cr alloy target onto various substrates. The microstructure, hardness, and stress behavior of the as-deposited and annealed coatings have been investigated.
