Advanced technical ceramics - Methods of test for ceramic coatings - Part 13: Determination of wear rate by the pin-on-disk method

Scope

1.1 This part of EN 1071 describes a method for evaluating the wear of ceramic coatings by use of a test in which a flat or spherically ended pin is brought, under load, into contact with the flat surface of a disk and the two are set in relative motion such that the pin describes a circular path on the disk. Depending on the conditions being simulated, either the pin or disk 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.
1.2 Where suitable equipment is available, the test may be used to determine the friction generated in the sliding contact.
1.3 The method is suitable for evaluating coatings in the thickness range from 1 to more than 100μm, and with suitable choice of conditions might also be applicable to testing thinner coatings.
1.4 Testing may be under either dry or lubricated conditions. However, the test is not designed for evaluating the properties of lubricants except in so far as they affect the wear behaviour of the materials being tested. Related methods for testing lubricants using a reciprocating motion are given in references [4] – [6].
1.5 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.
