Abstract

Purpose

The purpose of this study is to reveal the effect of nano-Al₂O₃ particle addition on the nucleation/growth kinetics, microhardness, wear resistance and corrosion resistance of Co–P–xAl₂O₃ nanocomposite plating.

Design/methodology/approach

The kinetics and properties of Co–P–xAl₂O₃ nanocomposite plating prepared by electroplating were investigated by electrochemical measurements, scanning electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy, Vickers microhardness measurement, SRV5 friction and wear tester and atomic force microscopy.

Findings

A 12 g/L nano-Al₂O₃ addition in the plating solution can transform the nucleation/growth kinetics of the plating from the 3D progressive model to the 3D instantaneous model. The microhardness of the plating increased with the increase of nano-Al₂O₃ content in plating. The wear resistance of the plating did not adhere strictly to Archard’s law. An even and denser corrosion product film was generated due to the finer grains, with a high corrosion resistance.

Originality/value

The effect of different nano-Al₂O₃ addition on the nucleation/growth kinetics and properties of Co–P–xAl₂O₃ nanocomposite plating was investigated, and an anticorrosion mechanism of Co–P–xAl₂O₃ nanocomposite plating was proposed.

添加纳米 Al2O3 粒子对电镀 X65 钢的 Co-P-xAl2O3 纳米复合镀层的影响

目的本研究旨在揭示纳米 Al2O3 颗粒的添加对 Co-P-xAl2O3 纳米复合镀层的成核/生长动力学、显微硬度、耐磨性和耐腐蚀性的影响。通过电化学测量、扫描电子显微镜、X 射线衍射、X 射线光电子能谱、维氏显微硬度测量、SRV5 摩擦磨损测试仪和原子力显微镜研究了电镀法制备 Co-P-xAl2O3 纳米复合镀层的动力学和性能。研究结果在镀液中添加 12 克/升的纳米 Al2O3 可使镀层的成核/生长动力学从三维渐进模型转变为三维瞬时模型。镀层的显微硬度随纳米 Al2O3 含量的增加而提高。镀层的耐磨性并不严格遵循阿卡德定律。原创性/价值研究了不同纳米 Al2O3 添加量对 Co-P-xAl2O3 纳米复合镀层成核/生长动力学和性能的影响，并提出了 Co-P-xAl2O3 纳米复合镀层的防腐机理。

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.
