Chromic Anodising
The chromic anodising process is used primarily in the Automotive, Aircraft and Ammunition industries and uses a chromic acid solution which produces a very thin coating, typically 2-5 microns. This is a moderately soft coating but offers excellent corrosion resistance. Due to the nature of the coating the film has an open pore structure which creates an excellent surface key for paint application. This is the preferred process to use when an important factor of your requirement is to minimise fatigue loss.
Applications include:
- Parts that require paint or adhesive to be applied
- Parts which require corrosion protection
- Parts which require low levels of electrical resistance or insulation
- Parts which are required to be inert, such as those in contact with propellants or explosives.
- Airframe parts and aircraft components
- Widely used in military components
