Advanced technical ceramics - Methods of test for ceramic coatings - Part 12: Reciprocating wear test
1.1 This European Standard describes a method for evaluating the wear of ceramic coatings by use of a reciprocating wear test whereby a flat or spherically ended pin is reciprocated, under load, against a flat plate. Depending on the conditions being simulated, either the pin or plate or both may be coated with the material under test, with the other member of the couple being selected for its relevance to the system under evaluation. The method described is considered to be not suitable for evaluating fretting wear.
1.2 The method is intended for evaluating coatings with a thickness of more than 1 μm, though might also be used for testing thinner coatings.
1.3 The test may be carried out under either dry or lubricated conditions. However, the test is not designed for evaluating the properties of lubricants except insofar as they affect the wear behaviour of the materials being tested. Related methods for testing lubricants using reciprocating motion are given in references [4] to [6].
1.4 Testing a materials couple under a range of loading conditions might provide information about the adhesive and/or cohesive strength of the coating, in addition to its wear behaviour.
Hochleistungskeramik - Verfahren zur Prüfung keramischer Schichten - Teil 12: Schwingungs-Verschleißprüfung
1.1 Diese Europäische Norm legt ein Verfahren zur Bewertung des Verschleißes keramischer Schichten durch eine Schwingungs Verschleißprüfung fest, bei der ein Prüfstift mit flachem oder kugelförmigem Ende unter Krafteinwirkung auf einer Prüfplatte hin und herbewegt wird. In Abhängigkeit von den zu simulierenden Bedingungen werden entweder der Stift oder die Platte oder beide mit dem zu prüfenden Werkstoff beschichtet, wobei die Elemente der Prüfanordnung hinsichtlich ihrer Relevanz für das zu prüfende System ausgewählt werden. Das festgelegte Verfahren ist nicht zur Bewertung von Reibverschleiß geeignet.
1.2 Das Verfahren ist zur Bewertung von Schichten mit einer Dicke größer 1 µm vorgesehen, es könnte jedoch auch zur Prüfung dünnerer Schichten verwendet werden.
1.3 Die Prüfung wird trocken oder mit Schmierung durchgeführt. Sie ist jedoch nicht zur Bewertung der Schmierstoffeigenschaften vorgesehen, außer insoweit, wie Schmierstoffe das Verschleißverhalten der zu prüfenden Werkstoffe beeinflussen. Verfahren zur Prüfung von Schmierstoffen durch Hin und Herbewegung werden in [4] bis [6] angegeben.
1.4 Die Prüfung einer Werkstoffpaarung unter unterschiedlichen Beanspruchungsbedingungen liefert u. U. außer Informationen zum Verschleißverhalten der Schicht auch Angaben zu ihrer Haft und/oder Kohäsions-festigkeit.
Céramiques techniques avancées - Méthodes d'essai pour revêtements céramiques - Partie 12 : Essai d'usure en va-et-vient
1.1 Cette norme européenne décrit une méthode d’évaluation de l’usure des revêtements céramiques par
un essai d’usure en va-et-vient où une broche à extrémité plate ou sphérique effectue un mouvement de vaet-
vient, sous charge, contre une plaque plate. Selon les conditions simulées, la plaque ou la broche, ou les
deux, peuvent être revêtues du matériau soumis à essai, l’autre membre du couple étant sélectionné pour sa
pertinence par rapport au système soumis à évaluation. La méthode décrite est considérée comme non
adaptée à l’évaluation de l’usure de contact.
1.2 La méthode d’essai est destinée à l’évaluation des revêtements ayant une épaisseur supérieure à
1 μm, bien qu’elle puisse également être appliquée à des revêtements de moindre épaisseur.
1.3 Les essais peuvent être effectués à l'état sec ou lubrifié. Néanmoins, les essais ne sont pas destinés à
évaluer les propriétés des lubrifiants, sauf dans la mesure où celles-ci influencent le comportement à l'usure
des matériaux soumis à essai. Les méthodes permettant de soumettre les lubrifiants à essai en utilisant un
mouvement de va-et-vient sont indiquées dans les références [4] – [6].
1.4 L’essai effectué sur un couple de matériaux dans une plage de conditions de charge peut fournir des
informations relatives à la résistance adhésive et/ou cohésive du revêtement, outre son comportement à
l’usure.
Sodobna tehnična keramika - Metode za preskušanje keramičnih prevlek - 12. del: Preskus obrabe
Ta evropski standard opisuje metodo za ocenjevanje obrabe keramičnih prevlek z uporabo preskusa obrabe, pri katerem se ploščata ali kroglasto zaključena igla pod obtežbo premočrtno premika glede na ravno ploščo. V odvisnosti od simuliranih pogojev sta lahko bodisi igla ali plošča, ali oboe, prevlečeni z materialom, ki se preskuša, pri čemer je drugi del para izbran zaradi svoje pomembnosti za sistem, ki se ocenjuje. Šteje se, da opisana metoda ni primerna za ocenjevanje fretting obrabe. Metoda je namenjena ocenjevanju prevleke z debelino več kot 1 μm, čeprav se lahko uporablja tudi za preskušanje tanjših prevlek. Preskus se lahko opravi bodisi pod suhimi ali mazanimi pogoji. Vendar pa preskus ni zasnovan za ocenjevanje lastnosti maziv, razen v kolikor vplivajo na obnašanje preskušanih materialov pri obrabi. Povezane metode za preskušanje maziv z uporabo izmeničnega gibanja so podani v referencah [4] - [6]. Preskušanje para materialov pod razponom obtežbenih pogojev lahko zagotovi podatke o sprijemni trdnosti in/ali kohezijski trdnosti prevleke poleg njegovega obnašanja glede obrabe.

SIST EN 1071-12:2010
Introduction Proper evaluation of the wear performance of ceramic coatings is essential to understanding their behaviour and to increasing their use in applications where high performance and predictable life are critical requirements, for example in the aerospace, automotive and biomedical industries. This part of EN 1071 describes a technique for the determination of the wear behaviour of a ceramic coating by reciprocating, under load, a flat or spherically ended pin against a flat plate. Depending on the information required, either the plate or pin or both may be coated with the material under test, with the other member of the couple being selected for its relevance to the system under evaluation. Wear is determined by weight loss, by profilometry, by linear measurement or by a combination of these. Coatings may be tested under dry or lubricated conditions. Where suitable instrumentation is available, the test can provide important information about the friction generated in the system. In addition to providing data on the frictional interaction in the system per se, monitoring of the friction can, by detecting changes in the level or trend of the friction force, provide important information about changes occurring during the test, e.g. removal or fracture of the coating, changes in wear mechanisms, etc. The test for use with bulk materials reciprocating under non-lubricated conditions is well described in [1]. The standard identifies the basic equipment requirements and the test critical parameters for testing ceramic coatings, and provides for appropriate operating procedures and measurement protocols to ensure their proper control. In addition, it provides for consistency in the analysis of data and in the treatment of errors.
This part of EN 1071 complements parts 6 [2] and 13 [3], which describe techniques for micro-scale abrasion wear testing and pin-on-disc wear testing of ceramic coatings respectively. SIST EN 1071-12:2010
