Oxidation behaviour of a MoSiBTiC alloy coated by a (Si+B) co-deposition pack cementation method
Source abstract
Abstract
A MoSiB based coating was applied to the 1st-generation MoSiBTiC alloy using pack cementation process. After conditioning at 1300 °C for 10 h in air, the coating developed into four layers: an oxide layer, a MoSi 2 layer with Mo 5Si 3 and MoB precipitates, a Mo 5Si 3 layer, and a MoB+Mo 5SiB 2 (T 2 ) layer. However, visible holes often formed in the coating due to defects, and the oxidation proceeded to the substrate during subsequent cyclic oxidation. In a controlled test on a MoSiBTiC alloy with lower TiC volume fraction, an intact coating formed after the conditioning at 1300 °C and provided an effective oxidation resistance.
