摘要

目的本研究旨在探讨 Al2O3 质量分数对 FeAl-xAl2O3 涂层腐蚀磨损和电化学行为的影响。设计/方法/方法采用激光熔覆法在 S355 钢上制备 FeAl-xAl2O3 涂层，以改善其腐蚀磨损和电化学性能。研究结果FeAl-xAl2O3 涂层的平均摩擦系数和磨损率随 Al2O3 质量分数的增加而降低，Al2O3 对耐腐蚀磨损性能起积极作用。此外，FeAl-xAl2O3 涂层的电荷转移电阻随 Al2O3 质量分数的增加而增加，表明 FeAl-15%Al2O3 涂层的耐腐蚀性最好。研究结果表明，FeAl-15%Al2O3 涂层的耐腐蚀性是三种涂层中最高的。

Microstructure, corrosive wear and electrochemical properties of Al2O3 reinforced FeAl coatings by laser cladding

Purpose

This study aims to investigate the influences of Al₂O₃ mass fraction on the corrosive wear and electrochemical behaviors of FeAl–xAl₂O₃ coatings.

Design/methodology/approach

FeAl–xAl₂O₃ 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–xAl₂O₃ 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–xAl₂O₃ 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/value

Al₂O₃ was first added into FeAl coatings to further improve its corrosive wear and electrochemical properties by laser cladding.

期刊介绍： Anti-Corrosion Methods and Materials publishes a broad coverage of the materials and techniques employed in corrosion prevention. Coverage is essentially of a practical nature and designed to be of material benefit to those working in the field. Proven applications are covered together with company news and new product information. Anti-Corrosion Methods and Materials now also includes research articles that reflect the most interesting and strategically important research and development activities from around the world. Every year, industry pays a massive and rising cost for its corrosion problems. Research and development into new materials, processes and initiatives to combat this loss is increasing, and new findings are constantly coming to light which can help to beat corrosion problems throughout industry. This journal uniquely focuses on these exciting developments to make essential reading for anyone aiming to regain profits lost through corrosion difficulties. • New methods, materials and software • New developments in research and industry • Stainless steels • Protection of structural steelwork • Industry update, conference news, dates and events • Environmental issues • Health & safety, including EC regulations • Corrosion monitoring and plant health assessment • The latest equipment and processes • Corrosion cost and corrosion risk management.
