摘要： A hollow niobium body is partially immersed in an electrolyte, and is rotatably arranged about an axis of rotation extending through an opening therein in such a manner, that in any position of the body there exists above the electrolyte surface and all parts of the interior surface of the body situated above the electrolyte level a vapor space communicating with the external environment through the opening. As the body is rotated no part of the interior surface remains in the electrolyte continually. The cathode is disposed in the body in such a manner that the gases formed at the cathode escape into said vapor space without contacting the immersed surfaces. For polishing, constant electric voltage is applied between the body and the cathode and adjusted in such a manner that damped current oscillations occur which are superimposed on the electrolytic current. Not later than after the complete decay of the current oscillations, the voltage is turned off until the oxide layer built up during the current oscillations is dissolved. Subsequently, a constant voltage is again adjusted in such a manner that damped current oscillations occur, and the sequence of states with the voltage turned on and off is repeated several more times. During the application of the constant voltage and the subsequent dissolution of the oxide layer, the body is kept at rest and its rotation about the axis of rotation is continued after the oxide layer is dissolved and before the constant voltage is applied again.
摘要翻译： 中空的铌体部分地浸没在电解质中，并且以这样一种方式围绕延伸穿过其中的开口的旋转轴线可旋转地布置：在电解质表面的上方存在的任何位置和内表面的所有部分 位于电解质上方的主体通过开口与外部环境连通的蒸汽空间。 当身体旋转时，内部表面的一部分不断地残留在电解质中。 阴极以这样的方式设置在主体中，使得在阴极处形成的气体不会接触浸入的表面而逃逸到所述蒸气空间中。 对于抛光，在体和阴极之间施加恒定的电压，并且以这样一种方式进行调节，使得产生叠加在电解电流上的阻尼电流振荡。 不迟于当前振荡完全衰减之后，电压被关闭，直到在当前振荡期间积聚的氧化物层被溶解。 随后，再次调整恒定电压，使得阻尼电流振荡发生，并且电压接通和断开的状态序列重复多次。 在施加恒定电压和随后的氧化物层溶解期间，保持静止，并且在氧化物层溶解之后并且再次施加恒定电压之前，其旋转轴在旋转轴线下继续。
