Abstract

Abstract

The modified Ti-Cr-Si silicide protective coatings on C-103 niobium alloys wereprepared by slurry-firing method. The chemical composition, microstructure, andproperties of the modified Ti-Cr-Si coatings were studied by means of optical microscope, energy dispersive X-ray diffractometer, RAX-10 diffractometer, EPMA-8705QH₂ etc. The experimental results showed that the oxidation-resistance of themodified Ti-Cr-Si coating at high temperature can be increased using appropriateadditives and substratum pretreating method.
