Problems solved by technology

[0003] The patent (CN 107445654 A) discloses a functional ceramic coating, which adds graphite components to prepare functional ceramics with antibacterial and bactericidal properties. However, graphite is an inorganic substance and it is difficult to fully mix it with ceramic powder. It is used as a raw material. The prepared coating is prone to the disadvantages of uneven mixing and poor comprehensive performance

Description

technical field [0001] The invention relates to a ceramic coating, in particular to a graphene-enhanced ceramic coating. Background technique [0002] With the development of society, people's demand for ceramics no longer satisfies a single function, such as beautiful appearance and smoothness, so a kind of functional ceramics has appeared, which has the characteristics of ordinary ceramics in terms of appearance and excellent functions. Incomparable advantages. Functional ceramics include two parts, the substrate and the coating. The coating covers the surface of the substrate, which can change the shape, color, and chemical structure of the ceramic surface, endowing it with rich properties, such as wear resistance and high temperature resistance. [0003] The patent (CN 107445654 A) discloses a functional ceramic coating, which adds graphite components to prepare functional ceramics with antibacterial and bactericidal properties. However, graphite is an inorganic subst...
