A mixture of CoNiCrAlY and talc powders is considered as a new candidate composition for abradable seal coating applications. Dense specimen having the composition of 1:20 weight ratio of talc with respect to CoNiCrAlY was prepared using the Spark Plasma Sintering (SPS) technique. The aim of the pre...
