will contact directly when the liquid products are removed out through the minute voids in coating, and the heat transfer capacity of the metal-coating interface reaches the maximum. As the temperature of the coating continues increasing, the burned organic ingredients in coating increase the amount of minute void in the coating, which decreases the heat transfer capacity of the coating. As the wide......
