Penulis telah menyiasat proses kemerosotan cincin gelincir bersalut Au dan sistem berus Ag-Pd dengan pelincir untuk merealisasikan jangka hayat yang stabil dan panjang. Melalui ujian yang lalu, dapat dijelaskan bahawa pelincir adalah sangat penting untuk jangka hayat yang panjang, dan model mudah proses kemerosotan telah dicadangkan. Walau bagaimanapun, ia masih menjadi isu bagaimana pelincir merosot dan juga apakah hubungan antara kemerosotan pelincir dan tingkah laku voltan sentuhan. Dalam makalah ini, bentuk gelombang voltan sentuhan telah direkodkan secara kerap semasa ujian, dan dianalisis untuk mendapatkan perubahan masa voltan puncak dan sisihan piawai semasa satu putaran. Berdasarkan keputusan ini, dibincangkan apa yang berlaku pada antara muka antara cincin dan berus dengan pelincir. Dan keputusan berikut dibuat dengan jelas. Turun naik bentuk gelombang voltan, terutamanya puncak turun naik seperti nadi lebih mudah berlaku untuk gelang tolak daripada gelang tambah. Selanjutnya, nilai puncak turun naik seperti nadi dengan cepat berkurangan dan hilang pada kelajuan putaran yang lebih rendah seperti yang dinyatakan dalam kerja-kerja sebelumnya. Di samping itu, setiap puncak turun naik seperti nadi dikenal pasti pada setiap kedudukan pinggir cincin. Daripada keputusan ini, boleh diandaikan bahawa filem pelincir wujud di antara permukaan berus dan cincin dan pengaliran elektrik direalisasikan oleh kesan terowong. Dalam erti kata lain, boleh dijelaskan dengan jelas bahawa turun naik akan disebabkan oleh lapisan pelincir, bukan sahaja oleh permukaan gelang. Akhir sekali, model pengaliran elektrik dicadangkan dan keputusan di atas boleh dijelaskan oleh model ini.

Abstract: The authors have been investigating the deterioration process of Au-plated slip-ring and Ag-Pd brush system with lubricant to realize stable and long lifetime. Through the past tests, it can be made clear that lubricant is very important for long lifetime, and a simple model of the deterioration process was proposed. However, it is still an issue how the lubricant is deteriorated and also what the relation between lubricant deterioration and contact voltage behavior is. In this paper, the contact voltage waveforms were regularly recorded during the test, and analyzed to obtain the time change of peak voltage and standard deviation during one rotation. Based on these results, it is discussed what happens at the interface between ring and brush with the lubricant. And the following results are made clear. The fluctuation of voltage waveforms, especially peaks of pulse-like fluctuation more easily occurs for minus rings than for plus rings. Further, peak values of the pulse-like fluctuation rapidly decreases and disappear at lower rotation speed as mentioned in the previous works. In addition, each peaks of the pulse-like fluctuation is identified at each position of the ring periphery. From these results, it can be assumed that lubricant film exists between brush and ring surface and electric conduction is realized by tunnel effect. In other words, it can be made clear that the fluctuation would be caused by the lubricant layer, not only by the ring surface. Finally, an electric conduction model is proposed and the above results can be explained by this model.
