The high temperature coating is applied on the surface of the substrate, which can form a high temperature protective layer. The non-insulation coating is a high temperature resistant coating. The coating cannot increase the temperature resistance range of the substrate, because the high temperature coating cannot prevent the amount of heat transfer to the substrate Once the temperature resistance limit of the substrate is reached, it may melt or deform. The temperature of the nanometer high-temperature coating is 1400 degrees, but this is the temperature range that the coating can achieve, and it is not really resistant If the temperature exceeds the temperature range of the substrate, it needs to be considered whether it is long-term temperature resistance or short-term temperature resistance.

Some people may ask, what's the use of high temperature coating? The metal is used at high temperature without any protection treatment. Even if the substrate can withstand temperature, it will face high temperature corrosion over time. After being coated with high temperature, it can not only maintain the temperature resistance, but also make the substrate resistant to high temperature corrosion. It is even resistant to direct scouring by flames and high-temperature airflow, extending the service life.
