Introduction to Conductive and Thermal Insulation Coatings

       In order to maintain the purity of the conductor material and make the performance of the coating material and the original spraying material completely consistent, the cold air power spraying technology can be used to prepare pure metal Cu and Ag high conductive coatings. The cold air power spraying can completely guarantee the performance of the coating and the original spraying material. Exactly. The plasma sprayed YBa2Cu3O7-x superconducting coating has a zero resistance temperature Tc>90K, which is higher than the boiling point temperature of liquid nitrogen (77K). Its magnetic transition temperature TB> 96K shows good application prospects, including applications in magnetic shielding, microwave components, various sensors, quantum electronic devices, etc.



Ceramic materials not only have high hardness and excellent wear resistance, but also have very good insulating properties. High-energy and high-speed plasma sprayed Al2O3 ceramic coatings have low porosity and high dielectric strength, and are currently one of the most ideal and widely used coatings for insulating coatings. If organic or inorganic substances are used to seal the Al2O3 ceramic coating, a better insulating effect will be obtained. The insulating coating has been used for the surface of the corona discharge roller that has been used to activate the polymer material film, and the effect is very good. .
