ABSTRACT:This effort seeks to develop a physics based model that can be used as a tool for interested parties within the industry to develop more advanced durable material solutions for current platforms. In order to maximize its usefulness, the model must take into account both the coating and substrate materials working together as an interactive system. The model must also account for environmental exposure (e.g. water, fluids, oxidation), dynamic and static strain effects, high temperature particulate impacts and abrasion, multi-frequency (low through high frequency inputs) vibrational effects, coefficient of thermal expansion mismatches between the coating and the substrate, etc.BENEFIT:The efforts associated with the sustainment and maintenance of specialty coatings on exhaust structures can be one of the significant cost drivers on state of the art platforms. One of the industry?s goals for quite some time has been to develop new coating materials that are more durable and require less sustainment and fewer maintenance operations. In order for the material developers to fully understand what is required, it would be very useful to fully understand the environment and the interactions between the coatings and the substrates upon which they are applied.
