| Abstract(in English) | Contact surfaces of mechanical relays and switches are often damaged by arc discharges and/or mechanical wear during switching operations. Conventionally, erosion and transfer characteristics of various contact materials under different load conditions have been mainly studied based on observation and evaluation of contact surfaces after switching operation tests. On the other hand, a further detailed study becomes possible if we can observe and numerically evaluate a growing process of surface damages (especially, growth of a crater) on contact surfaces during switching operations. For that purpose, we initiated construction of a numerical evaluation system of contact surface damages by way of an optical cross-section method, and as the first step, developed an evaluation system for surface profile of a sample placed on a stage. In this paper, outlines of the system, as well as some examples of measured data obtained thereby, are briefly explained. |
