Description

In the investigation of high-energy impact brought about at velocities exceeding the speed of sound, temperature distribution may exceed ranges that change the material phases. To overcome certain wear characteristics, it is important to formulate a thermal distribution through the structure in the immediate vicinity of the impact. In order to mitigate the effects observed at the point of impact, we have found that the application of coatings is influential. Research focuses on evaluating the effects of temperature distribution on the success of coating application considering friction, aerodynamic heating, and heat transfer. The impact velocity will be evaluated over ranges less than and greater than the speed of sound.
