“…Burnett and Rickerby [86,87] split up the driving forces for coating loss in three different components: (i) an elastic-plastic indentation stress; (ii) an internal stress component; (iii) tangential frictional stress. Considering the elastic-plastic deformation, Bull and Rickerby [88] suggested that,…”

The fundamental property which often dictates the performance of a coating is its adhesion to the substrate and thus there are many techniques to measure adhesion. The choice of methods is dependent on many factors such as the mechanical properties of the coating and substrate, the interface properties, the microstructure of the coating/substrate system, residual stress, coating thickness and the intended application. Most tests aim to introduce a stable interfacial crack and make it propagate under controlled conditions and model this process to determine adhesion. The corresponding models are either stress analysis-based or energy-based. With the advent of miniature systems and very thin functional coatings, there is a need for characterization of adhesion at small length scales and some specific tests have been developed which are not appropriate for thicker coatings. Among these, indentation and scratch methods have the widest range of applicability but it is necessary to analyse the failure mechanisms before choosing an appropriate model to extract adhesion parameters. This paper reviews the main quantitative adhesion tests for coatings and highlights the tests which can be used to assess submicrometre coatings and thin films. The paper also highlights the modelling and analysis methods necessary to extract reliable adhesion properties illustrating this with examples for submicrometre coatings on silicon and architectural glass.

“…The deposition conditions are summarized in acoustic emission detector's sensitivity AE: 1. The critical load L C , causing the loss of the coating adhesion to the material, was determined on the basis of the values of the acoustic emission, AE, and friction force, Ft and observation of the damage (Burnett & Rickerby, 1987;Bellido-Gonzalez et al, 1995) developed in the track using a LEICA MEF4A optical microscope. The microhardness tests of coatings were made with the SHIMADZU DUH 202 ultramicrohardness tester.…”

“…A progressive normal load was applied from 0.2 N to 25 N, for 10 mm, at 0.1 mm.s -1 sliding speed. In this test, the first critical load (LC1) was defined as the load (N) necessary to crack the film and the second (LC2) as the load necessary to remove the film and expose the substrate on track 12,13 .…”
