Hardcoat Anodizing

Hard coat anodizing is a process used to create a hard aluminum oxide layer on the surface of a part to improve its surface performance. It’s commonly used in various industries such as aerospace, automotive, medical, military, and more. The anodized surface provides enhanced wear and corrosion resistance as well as improved thermal and electrical insulation. The typically hardcoat anodized parts include pistons, cylinders, gears, and other high-wear components. Hard coat anodizing is a process used to create a relatively thick layer of hard aluminum oxide on a part’s surface to improve the component’s surface performance. It is often referred to as Type III anodizing and is suitable for high-performance applications. To ensure the best CNC machining surface finishes possible, choosing the appropriate type of anodizing is important. In the case of hard coat anodizing, the anodic layer is thicker and denser than the standard Type II anodizing. It’s ideal for CNC machined parts that require excellent hardness, wear resistance, and corrosion resistance. Therefore, hard coat anodizing is a suitable finishing solution for CNC machined parts.
