Hard Coat Anodizing

Hard coat aluminum anodizing type iii to achieve greater corrosion protection for use in extreme environments or with moving mechanical parts the aluminum anodizing process can exceed depths 10 microns.

Hard coat anodizing.

The only factor directly related to the hard coat anodizing process is coating thickness where imperfections in the substrate are grown and are thus dependent on coating thickness. Very thin coatings similar to those produced by chromic anodizing are known as type iib. Anodizing improves the metals resistance to corrosion wear and increases durability. Hardcoat anodize or simply hard anodize is a dense anodic coating of aluminum oxide applied by converting a properly cleaned and deoxidized aluminum alloy component into an oxide film using a suitable electrolyte typically sulfuric acid cooled to nearly freezing and applied voltages upwards of 100 volts at an applied current density of 24 36 amps per square foot.

Coatings of moderate thickness 1 8 μm to 25 μm 0 00007 to 0 001 are known as type ii in north america as named by mil a 8625 while coatings thicker than 25 μm 0 001 are known as type iii hard coat hard anodizing or engineered anodizing. As a regional national and international aluminum parts anodizing leader hardcoat inc. As a result this style of anodizing is also referred to as type iii or hard coat.

Anodizing is an electrochemical process that converts surface aluminum to aluminum oxide. The key difference between aluminum hard coating and standard anodization is that the process provides the surface with greater wear resistance and a smoother and harder finish. Hard coat anodizing is a method of anodizing aluminum. Hard coat anodizing further enhances these properties.
