By applying ceramic thermal spraying to metal materials, electrical insulation properties are added.
Thermal spraying is a surface modification technique that involves melting and spraying materials such as metals, ceramics, and cermets using various heat sources to form functional coatings on the substrate surface. By applying ceramic thermal spray to metal materials, electrical insulation properties can be added. Alumina is the most commonly used ceramic for achieving electrical insulation. As the thickness of the thermal spray coating increases, the breakdown voltage for insulation rises. However, if the coating is too thick, there is a risk of delamination, so care must be taken regarding the relationship with the substrate material. 【Breakdown Voltage Values of Ceramic Thermal Spray Coatings】 [Components of Thermal Spray Coatings: In Air / In Insulating Oil] ○ Alumina (Al2O3): 6.00V / 7.45V ○ Gray Alumina (Al2O3/3TiO2): 3.80V / 4.42V ○ Chromia (Cr2O3): 0.12V / 0.12V For more details, please contact us.
