Estudo da remoção de óleo da superfície de alumínio utilizando plasma frio

The increasing concern with the sustainable development ally with a bigger awareness with regard to the preservation of the environment has stinulated research in the most diverses areas of environmental correct technologies. Inside of this context the cold plasma technology represents an efficient, clean and economic alternative for oil removal of the metal surface. The objective of this work is to evaluate the removal of the oil of the aluminum surface being used the cold plasma process. The evaluation of the cleanness was made by means of the analysis of angle of contact and XPS.
