Metal treatments refer to various processes applied to metals to enhance their properties, such as strength, durability, and resistance to corrosion. Common methods include heat treatment, which alters the metal's structure through heating and cooling, and surface treatment, which modifies the outer layer to improve wear resistance or appearance. These treatments are essential in industries like automotive and aerospace, where materials must withstand extreme conditions. Techniques such as galvanization, which involves coating metal with zinc to prevent rust, and anodizing, used primarily on aluminum to increase corrosion resistance, are widely employed to ensure longevity and performance.
