Arc Burns. Localized points of surface melting caused by arcing between electrodes or ground and pipe surface.

电弧烧伤。由于电极(含接地极)与管子表面之间起弧而产生的局部表面熔化点。

The results show that the higher rough surface will result in the arcing more easily and form higher arc energy, the forms of wear are mainly abrasive wear and are erosion.

结果表明：表面越粗糙，越易起弧，形成更高的电弧能量，磨损形式主要是磨粒磨损、电弧侵蚀；
