Protect light aluminium components with a hard-wearing finish
Hard Anodising offers excellent protection to aluminium parts which, during their working life, will be subject to mechanical or harsh environmental conditions, typically in offshore industries. This process offers good mechanical strength, combined with exceptional wear resistance.
Due to the finer cell structure of this finish, this deposit is of a dark grey appearance, limiting the choice of post-anodising colouring but can be complemented by post treatment sealing in black or olive colouring using potassium dichromate or nickel acetate solutions.
Hard Anodising (Hardcoat) is an electrochemically produced layer of aluminium oxide on the surface of aluminium. A controlled thickness can be obtained from just a few microns up to 120 microns depending upon the alloy used.
The process is used to produce much thicker, harder and corrosion resistant coatings than the Sulphuric Acid process. The thickness can be very closely controlled, and the cool operating temperature of the process prevents thermal or physical distortion of precision engineered parts or equipment.
We also have the option of a post anodise PTFE impregnation for non-stick application often used for mould release. Typical finish thicknesses are in the range of 25-60 microns.
“Big shout out to Ben and the fantastic team at Premier Plating NE for their ongoing support and anodising these subsea housings recently to a top standard. EAG are supported by a fantastic supply chain and we greatly appreciate their efforts.”
