Anodizing
Anodizing is a protective coating process used to make metal surfaces (especially aluminum) more durable and attractive. Think of it like giving metal a protective skin that resists corrosion and wear while also allowing for coloring. This process creates a strong surface finish that's widely used in industries from architecture to consumer electronics. It's different from painting or plating because it actually changes the surface layer of the metal itself, making it more permanent. When someone mentions anodizing in their resume, they're typically talking about operating or supervising the equipment and processes that create these protective metal finishes.
