High-temperature-resistant (slurry-based) coatings

The development of high-temperature, oxidation-resistant coatings needs to be thoroughly studied owing to the metal loss incurred from short-or long-term exposure to high temperatures before final processing. Particularly, short-term exposure (intermittent heating or soaking or other heat treatment schedules) always produces often unwanted scales, which cause problems in subsequent metal working, loss of metal or further necessary pickling, etc. Studies the performance of some slurry-based coatings with regard to the protection of metals during shortterm exposure to high temperatures
