Study of Glass-Ceramic Coating on the SUS430 Stainless Steel Plate with High Temperature Oxidation Resistance

Abstract:

Currently, the ceramic inner container draws great attention in the field of induction heating pot. Based on the traditional roll-forming process for ceramic pot, a new kind process was proposed to fabricate ceramic inner container and synchronously embed stainless steel plate by one-step high temperature sintering. The key technology for this process is to avoid the oxidation of SUS430 stainless steel plate during the high temperature sintering for a longtime by coating a glass-ceramic layer. In this research, the glass-ceramic coating with excellent high temperature oxidation resistance was optimized. The influences of ZrO₂ content in the coating slurry on the high temperature oxidation resistance and thermal shock resistance of SUS430 stainless steel plate with glass-ceramic coating were studied. Meanwhile, the coatings were characterized by Scanning Electron Microscopy, X-ray Diffraction and Thermal Expansion Analysis. The experimental results showed that the glass-ceramic coating was smooth and had excellent thermal shock resistance when the addition of ZrO₂ reached 15wt%. The mass gain of the SUS430 stainless steel plate with glass-ceramic coating was only 0.453% after sintering at 1300°C for 10h in air atmosphere, which was less one percent than that of SUS430 stainless steel plate under the same sintering condition.
