dc.description.abstract |
Cyclic oxidation tests were performed on a large variety of commercially available overlay coatings. The results confirmed that the composition of the coating as well as the processing method of the coating can affect the life of the system. Coating life was determined by the time of coating penetration and initiation of substrate attack. As this work was part of an effort to evaluate the relative protectiveness of available coating systems for Industrial Gas Turbine applications at relatively high temperature, an extensive testing programme was undertaken. During testing an observation was made that in addition to the usual oxidation of the coating, another degradation mechanism was pragmatic; a mechanical effect caused by the instability of the coating as a result of the difference in the thermal coefficient of expansion and mechanical properties between the substrate and coating. This effect, known as the “rumpling” effect, resulted in a significant reduction in time of penetration and was in some systems the life controlling factor. |

The results confirmed that the composition of the coating as well as the processing method of the coating can affect the life of the system. Coating life was determined by the time of coating penetration and initiation of substrate attack. As this work was part of an effort to evaluate the relative protectiveness of available coating systems for Industrial Gas Turbine applications at relatively high temperature, an extensive testing programme was undertaken.
