ISO (הארגון הבינלאומי לתקינה) היא הפדרציה העולמית של גופי התקנים הלאומיים (גופים חברי ISO). פיתוח תקנים בינלאומיים מתבצע בדרך כלל באמצעות ועדות טכניות של ISO. Each member group interested in a subject on which a technical committee has been established has the right to be represented on the Committee. International, governmental and non-governmental organizations in liaison with ISO are also involved in this work. ISO עובד בשיתוף פעולה הדוק עם הנציבות האלקטרוטכנית הבינלאומית (חברת החשמל) בכל הקשור לתקינה חשמלית.

ISO 23737-2021 “קרמיקה משובחת (Advanced ceramics, קרמיקה טכנית מתקדמת) – Methods for evaluating the wear and friction characteristics of fine ceramic films under wet and dry conditions”

הצג
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, כְּלוֹמַר. 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. לָכֵן, 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 מיקרומטר, 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.

3 מונחים והגדרות
למטרות מסמך זה, המונחים וההגדרות הניתנים ב-ISO 20507 ולהלן חלים.

3.2 Friction force

The resistance exerted on a relative body when objects in contact move or tend to slide against each other

3.3 Friction coefficient

The dimensionless ratio of friction to the applied normal force

3.4 Wear test

Tests for the evaluation of friction and wear characteristics caused by sliding contact motion

הערה 1: In a narrow sense, the term “wear test” refers to the process by which wear occurs on the specimen as a result of sliding motion; In broad terms, it means processes such as sample preparation, wear formation, friction coefficient measurement, and evaluation of wear trajectoryand wear parts formed on the inverse material.

3.5 Drying Chamber

A sealed container for removing moisture from the surface of the sample while the sample is kept in a vacuum

3.6 לחות יחסית

Ratio of partial vapor pressure to saturated vapor pressure at a given temperature

3.7 Dry air

Air with a dew point of −60 °C or lower at an absolute pressure of 101.3 kPa

3.8 Dry Nitrogen

At an absolute pressure of 101.3 kPa, the dew point is −60 °C or lower nitrogen
