摘要

The results of studying the structure and properties of composite ceramic coatings produced by microarc oxidation (MAO) on zirconium alloy E110 are presented. To form the coatings, a suspension electrolyte is used with the addition of aluminum-hydroxide nanopowder. It is shown that the addition of the nanopowder results in a substantial increase in the growth rate and thickness of the coating compared with coatings obtained in the same amount of time without the addition of nanopowder to the electrolyte. A decrease in the porosity of coatings with increasing time of microarc oxidation is also revealed. It is found that samples with MAO coatings have a greater resistance to corrosion in an autoclave as compared to uncoated samples.
