Formation of MoSi2 and Si/MoSi2 coatings on TZM (Mo–0.5Ti–0.1Zr–0.02C) alloy by hot dip silicon-plating method

MoSi2 and Si–MoSi2 coatings were deposited on TZM alloy by using a hot dip silicon-plating method. The composite coatings mainly consist of MoSi2 and Si with a small amount of C/SiO2/ZrSi2. The composite coatings have fine MoSi2 grain size and higher surface silicon concentration. The diffusion layer mainly consists of MoSi2 layer and Mo5Si3C layer under the deposition time is 10 min. The diffusion layer is divided into three layers when the...
