Fine ceramics (advanced ceramics, advanced technical ceramics) - Rockwell indentation test for evaluation of adhesion of ceramic coatings (ISO/FDIS 26443:2023)

ISO 26443:2008 specifies a method for the qualitative evaluation of the adhesion of ceramic coatings up to 20 µm thick by indentation with a Rockwell diamond indenter. The formation of cracks after indentation may also reveal cohesive failure. The indentations are made with a Rockwell hardness test instrument.
The method described may also be suitable for evaluating the adhesion of metallic coatings.
The test is not suitable for elastic coatings on hard substrates.

Hochleistungskeramik - Rockwell-Eindringprüfung zur Bewertung der Haftung von keramischen Schichten (ISO/FDIS 26443:2023)

Dieses Dokument legt ein Verfahren zur qualitativen Bewertung der Haftung keramischer Schichten mit einer Dicke von bis zu 20 µm fest, bei dem mit einem für die Rockwell Härteprüfung verwendeter Diamant Eindringkörper ein Eindruck erzeugt wird. Die Bildung von Rissen am Eindruck kann auch ein Kohäsionsversagen erkennen lassen. Die Eindrücke werden mit einem Rockwell Härteprüfgerät erzeugt.
Das in diesem Dokument beschriebene Verfahren kann auch zur Bewertung der Haftung metallischer Schichten geeignet sein.
Diese Prüfung ist für elastische Schichten auf harten Grundwerkstoffen nicht geeignet.

Céramiques techniques - Évaluation de l'adhérence des revêtements céramiques par l'essai de pénétration Rockwell (ISO/FDIS 26443:2023)

L'ISO 26443:2008 spécifie une méthode permettant l'évaluation qualitative de l'adhérence de revêtements céramiques jusqu'à 20 µm d'épaisseur par indentation à l'aide d'un pénétrateur diamanté de Rockwell. La formation de fissures après l'indentation peut également révéler une rupture cohésive. Les indentations sont réalisées à l'aide d'un instrument d'essai de dureté Rockwell.
La méthode décrite dans la présente Norme internationale peut également être adaptée à l'évaluation de l'adhérence de revêtements métalliques.
L'essai n'est pas adapté aux revêtements élastiques sur des substrats durs.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non­governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO document should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
