Abstract
  Thermal barrier coatings (TBCs), advanced ceramic systems, are usually applied to the surface of hot industrial parts to improve equipment performance at higher temperatures. During each thermal cycle, the layers of the TBC system expand and contract unevenly due to the mismatch in the coefficients of ...  Read More

Abstract
  Space systems in Low Earth Orbit (LEO) are exposed to the destructive parameter of atomic oxygen. In long-term missions, the rate of degradation of the material resulting from the reaction with atomic oxygen is significant and reduces the performance of the structure. Due to the harmful effects of atomic ...  Read More
