摘要
本文致力于研究在碱-硅酸盐、硼酸盐和碱-硅酸盐-磷酸盐电解质中,利用阴阳极模式通过微弧氧化(MAO)获得的陶瓷涂层的结构和机械性能。使用硼酸盐电解质形成的涂层具有最佳的机械性能,使未受保护的铝表面的耐磨性提高了 2.1 至 3.1 倍,具体取决于所用电解质中硼酸根离子的含量。陶瓷 MAO 涂层为俄罗斯维修和保养企业提供了使用潜力,这些企业从事农业机械关键部件所用磨损铝和钢材料的维修和修复工作。
Effect of Electrolyte Composition on the Structure and Tribological Properties of Ceramic Coatings Obtained by Micro-Arc Oxidation
The paper is dedicated to studying the structural and mechanical properties of ceramic coatings obtained by micro-arc oxidation (MAO) using a cathodic-anodic mode in alkali-silicate, borate, and alkali-silicate-phosphate electrolytes from an experimental sample of compositions. Coatings formed using borate electrolyte have the best mechanical properties, resulting in the improvement of wear resistance of an unprotected aluminum surface by 2.1 to 3.1 times, depending on the content of borate ions in the utilized electrolyte. Ceramic MAO coatings offer a potential for use at the Russian repair and maintenance enterprises, which are engaged in the repair and restoration of worn aluminum and steel materials used in critical components of agricultural machinery.
