Abstract

The invention relates to ceramic coating with marine organism corrosion resistance as well as a preparation method therefore, belonging to the technical field of ceramics. The ceramic coating comprises the following components in parts by weight: 15-30 parts of magnesium oxide, 50-70 parts of aluminum oxide, 5-20 parts of silicon dioxide and 2-20 parts of zinc oxide. The preparation method comprises the following steps of: firing the components for 30 minutes-100 minutes at a high temperature of 800 DEG C-1500 DEG C; and taking out and cooling to the room temperature to obtain the ceramic coating with the marine organism corrosion resistance. The ceramic coating disclosed by the invention not only keeps original characteristics of wear resistance, high temperature resistance, oxidization resistance and the like of the ceramic coating; meanwhile, the aluminum oxide is added, so that the marine organism corrosion resistance of the coating is remarkably improved, and application of the ceramic coating on components of ships and warships is expanded.

Description

technical field [0001] The invention relates to a ceramic coating resistant to marine organism corrosion, in particular to a ceramic coating resistant to marine organism corrosion and a preparation method thereof, belonging to the technical field of ceramic production. Background technique [0002] With the development of maritime traffic, the proportion of ship repair and maintenance to the cost of navigation is gradually increasing. How to reduce the cost of ship repair and maintenance is one of the main problems faced by various shipping companies. Among all the ship repair work, the repair and maintenance of ship parts due to seawater corrosion is particularly prominent and accounts for the largest proportion of repair costs. Ships have been immersed in seawater for many years, and they are inevitably corroded by seawater and marine microorganisms, resulting in varying degrees of damage to parts and components. Therefore, it is very important to research and develop a ma...
