An aluminum base is hard-anodized to form an aluminum oxide substrate on a surface of the aluminum base.

The base of the inner shell incorporates a thick layer of oxide, black in colour, formed by hard anodizing, favouring infrared irradiation.

For example, hard anodized aluminum is used for surface protection in the automotive industry.

The system of the present invention forms, at one time, a film having a desired thickness on the object to be plated in the single electrolytic cell through hard anodizing.

In a second production step, the initial surface is hard-anodised in an electrolyte bath (6) to create an intermediate surface.

RESIF Technologies Bel Company offers its customers a new service for the electrochemical surface treatment of aluminum alloys – HARD ANODIZING (also known as hardcoat).

The chamber component includes a polished high purity aluminum coating and a hard anodized coating that is resistive to the plasma processing environment.

And a total commitment to corrosion protection utilizing hard-coat anodizing and a superior multi-step paint process.

A metallic dental fixing element, in particular bracket, is made of an aluminium alloy with a hard anodized surface.

Hard-Anodized Construction starts with heavy-gauge, commercial quality aluminum that becomes twice as hard as stainless steel.
