EN 1071-2:2002 (E)41 ScopeThis part of this European Standard specifies a method for the determination of the thickness of ceramic coatings by acrater grinding method which includes the grinding of a spherical cavity and subsequent microscopic examination ofthe crater.NOTEAn alternative measurement of thickness, using a contact probe profilometer, is specified in EN 1071-1.2 Normative referencesThis European Standard incorporates by dated or undated reference, provisions from other publications. Thesenormative references are cited at the appropriate places in the text, and the publications are listed hereafter. Fordated references, subsequent amendments to or revisions of any of these publications apply to this EuropeanStandard only when incorporated in it by amendment or revision. For undated references the latest edition of thepublication referred to applies (including amendments).EN ISO/IEC 17025 General requirements for the competence of testing and calibrationlaboratories (ISO/IEC 17025:1999)ISO 3290Rolling bearings – Balls – Dimensions and tolerances.3 Significance and useThe coating thickness often plays a major role in the performance of coated tools and machine parts. Manydifferent techniques have been developed for assessing the coating thickness. Among these, the crater grindingmethod and the step height method (see EN 1071-1) are methods that are easy to perform and applicable to mostcoated systems.The method is simple and straightforward. A crater is ground into the coated part by means of a rotating ball wetted byan abrasive slurry. The thickness of the coating is derived from the ball and crater dimensional characteristics.Contrast between the different materials constituting the coating and substrate is a prerequisite for the method toenable the detection of the interface between the coating and the surface.NOTETest specimens should be either flat or cylindrical. Flatness can be considered as sufficient if the local specimenradius of curvature, Rs, satisfies the relation Rs > 100 × R (for error £ 1 %).4 SamplingA representative test specimen of the product under test shall be used. Test pieces shall be coated original items, orwhere this is not possible, made in the same way as the batch to be tested. For large parts, separate manufacturing ofthe test piece may be necessary.SIST EN 1071-2:2004
EN 1071-2:2002 (E)55 Test procedure5.1 GeneralA ball wetted by an abrasive suspension is rotated against the surface of the test piece. A spherical wear crater isthus produced, and the test is finished when the depth of penetration of the spherical crater is greater than the coatingthickness. The coating thickness is then derived from the size of the wear scars (full crater and substrate craterwidths) and the ball diameter.NOTE 1Different set-ups of test rigs can be used. The ball can be rotated freely on a drive shaft, whereby its mass is usedto produce the contact load, or it can be clamped in the drive axis while the specimen is loaded by means of a lever system.Alternatively, a wheel instead of a ball can be used, in which case the sample must also be rotated (this is the same principle asdimple grinder used for
