Fine ceramics (advanced ceramics, advanced technical ceramics) - Determination of adhesion of ceramic coatings by scratch testing (ISO 20502:2005 including Cor 1:2009)

ISO 20502:2005 describes a method of testing ceramic coatings by scratching with a diamond stylus. During a test, either a constant or increasing force normal to the surface under test is applied to the stylus, so as to promote adhesive and/or cohesive failure of the coating-substrate system. The test method is suitable for evaluating ceramic coatings up to a thickness of 20 micrometres and might also be suitable for evaluating other coating types and thicknesses.

Hochleistungskeramik - Bestimmung der Haftung von keramischen Schichten mit dem Ritztest (ISO 20502:2005 einschließlich Cor 1:2009)

Diese Internationale Norm beschreibt ein Verfahren zur Prüfung keramischer Beschichtungen durch Ritzen mit einem Diamantstift. Bei einer Prüfung wird auf den Stift entweder eine konstante oder zunehmende Kraft senkrecht zur untersuchten prüfende Oberfläche aufgebracht, um Adhäsions- und/oder Kohäsionsversagen des Systems BeschichtungSchicht/Grundwerkstoff zu begünstigen. Das Prüfverfahren ist für die Bewertung keramischer Beschichtungen Schichten mit Dicken bis zu 20 µm geeignet und könnte auch für die Bewertung weiterer Schichtarten und -dicken geeignet sein.
Die Internationale Norm ist für die Anwendung im Makrokraftbereich (1 N bis 100 N) vorgesehen. Die Verfahren dürfen außerdem auf weitere Kraftbereiche angewendet werden. Wenn jedoch die Normalkräfte, bei denen Schichtversagen auftritt, quantitativ bestimmt werden sollen, ist eine geeignete Kalibrierung unerlässlich.

Céramiques techniques - Détermination de l'adhérence des revêtements céramiques par essai de rayure (ISO 20502:2005, y compris Cor 1:2009)

L'ISO 20502:2005 décrit une méthode destinée à tester la tenue des revêtements céramiques en les rayant avec un stylet diamanté. Au cours d'un essai, une force constante ou croissante, normale à la surface sollicitée, est appliquée sur un stylet de manière à provoquer une rupture adhésive et/ou cohésive du système revêtement-substrat. La méthode d'essai permet d'évaluer des revêtements céramiques dont l'épaisseur va jusqu'à 20 µm et peut aussi convenir pour évaluer d'autres types de revêtements et d'autres épaisseurs.
L'ISO 20502:2005 est destinée à être utilisée dans la plage des macro-forces (de 1 N à 100 N). Cependant, les modes opératoires peuvent également être applicables à d'autres plages. Un étalonnage approprié est toutefois nécessaire si les forces normales auxquelles se produit la rupture doivent être quantifiées.

Fina keramika (sodobna keramika, sodobna tehnična keramika) - Ugotavljanje adhezije keramičnih prevlek s preskusom praskanja (ISO 20502:2005, vključno s popravkom Cor 1:2009)

Ta mednarodni standard opisuje metodo preskušanja keramičnih prevlek s praskanjem z diamantno konico. Med preskusom se s konico pritiska na preskušano površino s konstantno ali vedno večjo silo, običajno za to površino, da se spodbudi odpoved adhezije in/ali kohezije sistema substrata prevleke. Preskusna metoda je primerna za ocenjevanje keramičnih prevlek debeline do 20 μm, prav tako pa se lahko uporabi za ocenjevanje drugih vrst prevlek in debelin. Mednarodni standard je namenjen za uporabo v razponu makro (od 1 do 100 N) sile. Postopki so lahko uporabni tudi za druge razpone sile. Vendar je za določanje moči običajnih sil, pri katerih pride do odpovedi, bistvenega pomena ustrezno umerjanje.
