  • Publication number: 20120012575
    Abstract: An apparatus for heating a target comprises a radio frequency heating fork having two substantially parallel tines, the substantially parallel tines electrically connected at a loop end of the radio frequency heating fork, and the substantially parallel tines separated at an open end of the radio frequency heating fork, and a feed coupler connection, the feed coupler connection connecting a power source across the substantially parallel tines of the radio frequency heating fork. The application of power across the substantially parallel tines of the radio frequency heating fork results in induction heating near the loop end of the radio frequency heating fork, and dielectric heating near the open end of the radio frequency tuning fork. A target can be positioned relative to the heating fork to select the most efficient heating method. The heating fork can provide near fields at low frequencies for deep heat penetration.

    Abstract: The present invention relates to the development of variants of multilayer structural materials with enhanced corrosion resistance, including successively connected outer main layers which directly contact corrosive operating environments on one or both sides of the multilayer material and, disposed therebetween, alternating internal main and internal sacrificial layers. The main layers are made of metallic materials which are characterized by a state of passivity over a prolonged period with subsequent development therein of pitting-type corrosion, while the internal sacrificial layers, which contact the corrosive operating environment as deep foci of pitting corrosion develop in the preceding outer and internal main layers, are characterized by the development of general corrosion and have a protective action in relation to the outer and internal main layers. Methods for preparing such materials are proposed.
