Modified Hardcoat Anodizing

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

 

Modified hardcoat anodizing (sometimes called hardcoating or hard anodizing) is an electrochemical process that provides corrosion protection to aluminum and aluminum alloy parts or pieces. Modified hardcoat anodizing creates a surface coating with hardness characteristics second only to diamonds.

Modified Hardcoat Anodizing: Features & Benefits of Hard Coating

Our state-of-the-art high capacity production facilities can hardcoat a wide variety of components, in sizes up to 32' long. Modified hardcoat anodizing offers a variety of beneficial properties:

  • Corrosion Resistance
  • Variable Thickness – smaller tolerances than previously available
  • Hardness – Rockwell scale rating of C - 60 / 70
  • Wear Resistance
  • Electrical Resistance
  • Temperature Resistance
  • Low Friction Coefficient
  • Clear or black
  • No thermal or physical distortion - modified hardcoating is a cool process
  • Coating becomes part of the component, penetrating into the base metal as much as it builds up on the surface

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

 

Modified Hardcoat Anodizing: Functions and Uses

Modified hardcoat anodizing is ideally suited for many product applications. Various techniques can be employed to enhance the corrosion resistance or abrasion resistance of the treated surface.

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

  • Pistons
  • Cylinders
  • Cams
  • Gears
  • Swivel Joints
  • Hydraulic / pneumatic Components
  • Applications where metal parts touch or rub each other

Modified hard coating can be applied to a wide range of types and sizes of aluminum components in our high capacity production facilities, including:

  • Large Sized Parts – up to
    33' 6"L X 5'H X 30" 
    W
  • Specialized tooling for modified hardcoating throws coating in long lineal lengths, down tubing with internal bores as small as 7/8", for pneumatic cylinders, hydraulic cylinders, etc.
  • Wire Coils
  • Gears, wheels, pulleys, etc
  • Extrusions
  • Fabricated Extrusion
  • Break Metal
  • Panels
  • Piece Parts

Modified Hardcoat Anodizing: Things to Consider

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