소개하다
Fine ceramic films are used in a variety of applications, such as sensors, actuators or other micromechanical components; Display element; Memory element; Recording media; Optical element; Packaging film; And films and glass for buildings and vehicles. In the industrial application of fine ceramic films, wear resistance is an important index for evaluation. The wear resistance of fine ceramic films is greatly affected by the ambient humidity and the humidity history of the films. Fine ceramic films are also used in different humidity environments where criteria are required to evaluate wear resistance and friction coefficient over a wide humidity range. The standards published to date for wear resistance testing only assume a temperature environment of 23 °C and a relative humidity of 50 %. The thickness of the film to be measured is also relatively large, with a few to 10μm. These test procedures are not suitable for evaluating the wear resistance of fine ceramic films with thickness up to approximately 1 µm for use in electronic and optical devices because the wear resistance of small indentation loads is affected by the relative humidity of the test environment, 즉. the mechanism used in the wear testing of fine ceramic films with small indentation loads is strongly affected by the relative humidity of the test environment. 그러므로, the wear test of fine ceramic film should be carried out under the specified relative humidity conditions. This document provides measurements that help accurately assess the wear resistance of fine ceramic films, up to a thickness of approximately 1 μm, deposited on thin substrates or organic polymer films, in dry and high humidity environments. The present document has been developed to facilitate industrial development through the rapid dissemination of these measurements.
