Abstract Plasma electrolytic oxidation (PEO) can be utilized for the in-situ ceramic coatings preparation on the surface of metals as a low cost and high efficiency surface modification method. In this technique, coatings having various surface compositions and morphologies and distinct properties can be provided by altering the electrical parameters and the composition and concentration of the solutions. The addition of particles of certain sizes into the solutions is beneficial in enhancing the function of PEO coatings. An example is zirconia (ZrO2) which is known as an effective additive in improving properties of PEO coatings which helps the coatings to have attractive features such as appropriate corrosion and wear resistance, high hardness, and excellent biocompatibility. The added ZrO2 particles to the solution improve the properties of the titanium oxide (TiO2) PEO coated titanium and its alloys by producing TiO2/ZrO2 composite. The present article reviews the studies which have investigated the influences of ZrO2 particles addition on mechanical and physical properties, wear and corrosion behavior, biological responses, and oxidation resistance of PEO oxide films applied on titanium and its alloys.

用氧化锆颗粒改善钛和钛合金上 PEO 涂层的表面特性：综述

摘要 等离子体电解氧化（PEO）是一种低成本、高效率的表面改性方法，可用于金属表面原位陶瓷涂层的制备。在该技术中，可以通过改变电参数以及溶液的组成和浓度来提供具有各种表面组成和形态以及不同性质的涂层。在溶液中加入一定尺寸的颗粒有利于增强 PEO 涂层的功能。一个例子是氧化锆 (ZrO2)，它被认为是改善 PEO 涂层性能的有效添加剂，有助于涂层具有吸引人的特性，例如适当的耐腐蚀性和耐磨性、高硬度和优异的生物相容性。添加到溶液中的 ZrO2 颗粒通过产生 TiO2/ZrO2 复合材料改善了氧化钛 (TiO2) PEO 涂层钛及其合金的性能。本文回顾了研究添加 ZrO2 颗粒对钛及其合金上应用的 PEO 氧化膜的机械和物理性能、磨损和腐蚀行为、生物响应和抗氧化性的影响。
