AMORPHOUS CARBON LAYER FOR HEAT EXCHANGERS

摘要

Process for deposition an amorphous carbon layer on substrates, such as heat exchangers, and the coated substrates so formed, such as an aluminum fined heat exchanger. The heat exchanger comprises a heat sink having deposited on its extended surface a layer of an amorphous carbon coating (DLC) having a hardness of at least 2000Kg/mm<2>, a specific resistivity of at least 10<8> ohm cm, and a dielectric strength of at least 10<6> V/cm.
