Understanding and Mitigating Oxidation in Forgings

The oxidation process of forgings refers to the phenomenon where metal reacts with oxygen at high temperatures, forming an oxide scale. During the forging process, especially in the heating stage, the surface of the forging is exposed to air or furnace gases, making oxidation inevitable. Oxidation not only affects the surface quality and dimensional accuracy of the forging but may also impact its mechanical properties and subsequent processing and assembly. Therefore, understanding the oxidation...
