Abstract

A Mo(Si,Al)₂ coating is developed to protect Nb _ss/Nb₅Si₃ in situ composite by plasma spraying. The binary layers of this coating consist of an inner interdiffusion layer surrounded by Mo(Si,Al)₂ layer with C40 crystal structure. After oxidation at 1250°C for 100h, Mo(Si,Al)₂ coating exhibited an excellent protection against oxidation and good adherence to substrate. The oxidation curve followed parabolic law and even after oxidation at high temperature for 100h, the weight gain per unit area of Mo(Si,Al)₂ coating is 8.24mg/cm². No evident spalling of coating to substrate was observed but a continuous and compact layer of Al₂O₃ was formed on coating surface to prevent oxidation below coating and substrate.
