Metal treatment refers to various processes used to enhance the properties of metals, such as strength, durability, and resistance to corrosion. Common methods include heat treatment, which alters the metal's microstructure through heating and cooling, and surface treatment, which improves the surface characteristics by applying coatings or treatments. These processes are essential in industries like automotive, aerospace, and construction, where metal components must withstand harsh conditions. By applying appropriate metal treatment techniques, manufacturers can ensure that their products meet specific performance standards and extend their lifespan.
