  • MICRO-ARC ALLOY CLEANING METHOD AND DEVICE
    Publication number: 20100051594
    Abstract: A cleaning device and method utilizes an electric circuit including a power supply electrically attached through a first lead to the alloy structure and a second lead connected to a probe. A protective atmosphere is provided over the surface of the alloy that is to be cleaned. Electric energy supplied by the power source generates an electric arc between the probe and the surface of the structure within the protective atmosphere. The electric interaction created by the electric arc and the surface of the alloy removes built up undesired material.
