摘要：
Purpose - This study aims to investigate the influences of Al2O3 mass fraction on the corrosive wear and electrochemical behaviors of FeAl-xAl(2)O(3) coatings. Design/methodology/approach - FeAl-xAl(2)O(3) coatings were prepared on S355 steel by laser cladding to improve its corrosive wear and electrochemical properties. Findings - The average coefficients of friction and wear rates of FeAl-xAl(2)O(3) coatings are decreased with the Al2O3 mass fraction, and the Al2O3 plays a positive role in the corrosion wear resistance. Moreover, the charge transfer resistance of FeAl-xAl(2)O(3) coatings is increased with the Al2O3 mass fraction, showing the FeAl-15%Al2O3 coating has the best corrosion resistance. The findings show the corrosion resistance of FeAl-15%Al2O3 coating is the highest among the three kinds of coatings. Originality/valueAl(2)O(3) was first added into FeAl coatings to further improve its corrosive wear and electrochemical properties by laser cladding.
