What effect do porosity have on the life of thermal protective coatings in turbines?

The mechanical engineering doctoral student of Zanjan University said: The results of a doctoral research show that porosity and microcracks in thermal protective coatings become severe by creating stress concentration and changing the way of heat transfer, causing crack growth, separation of layers and reducing the life of these coatings in working conditions.
