Outline of Final Research Achievements |
The principal investigator of this research project has applied Nose-Hoover algorithm of first principle molecular dynamics simulations to study the effect of PGMs doping on the interfacial reactions. It was found that the crystal structures near the coating-substrate interface vary significantly with respect to the number of valence electrons of the doping element. The results of this finding were published on Acta Materialia and Materials Research Innovations.
In addition, the same method was applied to study the degradation of thermal barrier coatings by volcanic ash and relevant mitigation mechanisms. It was discovered that alumina reacts with volcanic ash to form new compounds of high melting temperatures, which remain in the solid phase within the engine operating temperatures.
