Modified Hard Coating

Hard Coating: Hardcoat Anodizing, Anodic Oxide Coating, Rockwell C-Scale Rating of 60 - 70, Corrosion / Electrical / Temperature Resistance, Low Friction Coefficient

Modified hard coating, (also known as hard coat anodizing or hard anodizing) is an electrochemical process that applies a corrosion resistant coating, chemically bonded to the surfaces of aluminum and aluminum alloy parts or pieces. This creates a surface coating with hardness characteristics second only to diamonds.

These are just a few of the industries that have benefited from the use of hard coated aluminum components for thousands of applications:

Hard Coating: Functions and Uses

Hard coating is ideally suited for many product applications. Our state-of-the-art high capacity production facilities can hard coat a wide variety of components, in sizes up to 32-feet long. Various techniques can be employed to enhance the corrosion resistance or abrasion resistance of the treated surface.

Hard coatings offers a wide range of color options:

• Various bronzes
• Black
• Many shades of gray
• Clear.

Modified hard coating provides lubrication properties that resist abrasion and corrosion, making it the ideal solution for:

Hard coating can be applied to a wide range of aluminum and aluminum alloy components:

Modified Hard Coating: Features & Benefits of Hardcoat Anodizing

Beneficial properties of hard coatings include:

• Corrosion Resistance
• Variable Thickness – smaller tolerances than previously available
• Hardness – Rockwell scale rating of C - 60 / 70
• Wear Resistance
• Resistance to chemicals, solvents and petroleum based products
• Electrical Resistance
• Temperature Resistance
• Low Friction Coefficient after Lubrication

Hard Coating: Things to Consider

There are a number of points to consider when planning to hardcoat aluminum parts. Modified hard coatings are not always the best option for every application.
