    • Substantial surface areas (10) can be treated by continuously magnetically moving an electric arc (14) on the surface substantially continuously around a general loop direction such as a circle, ellipse or oval and moving the surface so that the arc (14) treats a substantial surface area. The arc treatment can be used to clean or roughen a surface (10) and a reactant or treatment agent (140) can be brought to the arc (14) contact site to alter the surface (130) treated with the arc. Auxiliary treatments for the surface can precede or follow the arch treatment, or both. The invention produces very desirable surface properties including a mild roughness or matte condition suitable even for critical applications such as aluminum lithoplate. Other surface characteristics can include one or more of: capillarity, adhesion, uniform emissivity, stable oxide, cleansed of organic and other coating, matte or whiteness, paintability, and others.
    • 可以通过在诸如圆形,椭圆形或椭圆形的一般环形方向上基本连续地连续磁性地移动表面上的电弧(14)来处理实质表面区域(10),并移动表面,使得电弧(14) 实质表面积。 电弧处理可以用于清洁或粗糙化表面(10),并且反应物或处理剂(140)可以被带到电弧(14)接触位置以改变用电弧处理的表面(130)。 表面的辅助治疗可以在弓形治疗之前或之后,或两者兼有。 本发明产生非常理想的表面性质,包括适用于关键应用如铝板的温和粗糙度或无光泽条件。 其他表面特征可以包括以下中的一种或多种:毛细管,附着力,均匀的发射率,稳定的氧化物,有机和其它涂层的清洁,无光泽或白度,可涂饰性等。
