Abstract

Purpose

The purpose of this paper is to investigate the effect of plasma electrolytic oxidation (PEO) coatings and sealed PEO coatings on the corrosion resistance and cytocompatibility of a novel Mg-1Zn-0.45Ca alloy in simulated body fluid (SBF).

Design/methodology/approach

The microstructure, corrosion resistance and cytocompatibility of PEO coatings and phosphate conversion-treated PEO coatings were investigated and was compared with the bare Mg alloy.

Findings

The hot-extruded Mg-Zn-Ca alloy exhibit inhomogeneous microstructure and suffered from localized corrosion in the SBF. The PEO coating after phosphate conversion treatment offers enhanced protectiveness to the Mg alloy within an immersion period of up to 60 days, which is significantly improved compared with the performance of the PEO-coated Mg alloy, but the cytocompatibility was slightly decreased.

Originality/value

This work offers new perspective in balancing the protectiveness and cytocompatibility of bio-materials.

通过磷酸盐处理的 PEO 涂层增强新型生物兼容 Mg-1Zn-0.45Ca 合金在模拟体液中的抗腐蚀性

目的本文旨在研究等离子电解氧化（PEO）涂层和密封 PEO 涂层对新型 Mg-1Zn-0.45Ca 合金在模拟体液（SBF）中的耐腐蚀性和细胞相容性的影响。研究结果热挤压 Mg-Zn-Ca 合金显示出不均匀的微观结构，在 SBF 中受到局部腐蚀。磷酸盐转化处理后的 PEO 涂层在长达 60 天的浸泡期内增强了对镁合金的保护性，与 PEO 涂层镁合金相比性能显著提高，但细胞相容性略有下降。

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.
