Abstract

A B-modified silicide coating was prepared on the Nb-Si based alloy by Si-TiB₂ co-deposition at 1300 °C for 10 h. The results show that the two-layer coating is composed of a (Nb, X)Si₂ (X represents Al, Cr, Ti and Hf) + NbTiB₄ outer layer and a (Nb, X)Si₂ + Cr₂Nb inner layer. Static oxidation tests indicate that the mass gain of B-modified silicide coating was 2.39 mg/cm² after oxidation at 1250 °C for 100 h. The good oxidation resistance is attributed to the formation of a continuous and dense scale mainly consisting of glassy borosilicate.
