抄録

<p>Owing to recent home computerization, electrical corrosion of rolling bearings comes to arise in home appliances. In the rolling bearings, since the material of inner ring, outer ring and rolling elements is the same (high carbon-chromium bearing steel), galvanic electrical corrosion does not intend to arise. However, when a large electrical potential of difference worked between inner ring and outer ring and/or axis and housing, electrical discharge intended to happen with smashing through the oil film inside the bearing. If the phenomenon continued a long span of time, the noise and vibration of the bearing increased. This damage is called “electrical corrosion”. This is considered as one of the wear phenomenon. This article describes a formation state and a growth process of ridge mark as a result of electrical corrosion.</p>
