The Altim TD aluminium surface treatment process patented by French company Mofratech has huge application potential. Developed from a micro-arc oxidation process, it offers improved performance with regard to hardness, substrate adherence, wear and corrosion resistance and electrical and thermal insulation. Unlike thermal powder projection techniques, it can be used on the inside and the outside of parts and unlike rival chrome processes, the new process is non-polluting.

The numerous applications for the Altim TD process include lubricated and non-lubricated friction parts, high surface hard­ness parts, and parts for pneumatic and hydraulic systems. Aluminium treated using this process will often prove to be a good replacement for other materials including steel, bronze and solid ceramics. Application areas including automotive engineering, electronics, ships building and aerospace.
