摘要：
Fe-Al-Si alloys based on Fe-Al, Fe-Si and ternary Fe-Al-Si phases have been recently proved as the materials highly resistant to high-temperature oxidation. However, high brittleness limits their application as bulk materials. Therefore this work aims to test them as the protective coatings for the carbon steel and to test the high-temperature oxidation resistance of the coated samples. The coatings by FeAl32, FeAl35Si5 and FeAl20Si20 alloys were produced uncoventionally by the combination of mechanical alloying and spark plasma sintering. It has been shown that the best resistance against the oxidation in the air at 800 °C was reached in the case of the FeAl35Si5 coating. Fe-Al binary alloy coating oxidized more rapidly, while the FeAl20Si20 coating tended to delaminate. © 2019. Published by Manufacturing Technology.
