Effects of voltage on microstructure and oxidation resistance of SiB6-MoSi2 coating deposited by pulse arc discharge deposition
چکیده انگلیسی
To protect carbon/carbon (C/C) composites against oxidation, a SiB6-MoSi2 coating was prepared by pulse arc discharge deposition (PADD). The influence of deposition voltage on arc discharge sintering ability, microstructure and oxidation resistance of the SiB6-MoSi2 coatings was investigated. Results show that the oxidation resistance of the coating is improved when the voltage increases from 350 to 450 V. The dense and good crystallization SiB6-MoSi2 coating was obtained with sufficient arc discharge sintering energy when the voltage is 450 V. And the multilayer coatings can protect C/C composites from oxidation in air at 1773 K for 164 h with a weight loss of 2.04%. The evaporation of the molten glass layer and MoO3 is the main reason for the failure of the multilayer coatings.
