Functional coatings are interfacial materials that provide lubrication, friction reduction and resistance to friction, heat and water insulation, insulation and corrosion protection, hydrophilicity and hydrophobicity, high temperature resistance and oxidation resistance to the substrate. Depending on the field of application, they can be broadly divided into two categories: industrial coatings and medical device coatings. https://biocoating.cd-bioparti....cles.net/products/co
