aluminiumfor aerospace applicationsfor the aeronautical industry

SURFACE TREATMENT FOR CORROSION PROTECTION Deposition of a 10 to 50 μm layer of pure aluminum. Features : - Corrosion protection - Electrical continuity Remarks : Dimensions from centimeters to 2 meters, beyond that please consult us. Possibility of additional treatment (SiOx, chemical conversion, Surtec 650, Corralu, varnish, cetyl alcohol). Treatable materials : - Steels - Stainless steels - Aluminium alloys - Refractory alloys - Titanium - Any metal compatible with vacuum deposition - Application possible on plastics, glass and ceramics. Application examples : - Combat aircraft structural parts - Screws and bolts - Aeronautics - On-board electronics housings - Sensor supports - Connector bodies HEF uses 3 main methods to generate its plasmas and produce high-quality coatings: PEMS™: PEMS™ technology enables the production of very dense layers for tribological use. More specifically, this process is used by the HEF Group to produce its hard or extra-hard layers with a low coefficient of friction. PEMS™ technology also makes it possible to modify the hardness, density and strength of the deposits to suit the application. CAM™: At the cutting edge of vacuum technology, CAM™ technology represents a real evolution by enabling the deposition of hard, ultra-low-friction coatings at an extremely low temperature. M-ARC™: This method is an evolution of the usual arc evaporation technique. It considerably reduces the droplets usually associated with this type of coating.
