The impact test has been used for several years, among others, for characterizing the fatigue strength, creep, adhesion and residual stresses of coatings at ambient and elevated temperatures under dry or lubricated conditions. A major advantage of this test method is that in many cases, it can be employed directly on the coated parts and not on specimens. The obtained experimental results are evaluated by convenient finite element method (FEM)-supported algorithms. Based on these algorithms, critical data for predicting the life span of coated parts such as cutting tools and bearings and for planning appropriate replacements can be obtained. The paper provides an overview of the development of impact test devices, experimental techniques and result evaluation methods. Characteristic examples highlighting the quantification of the fatigue strength of PVD (Phyical Vapour Deposition) coatings and their adhesion via the critical equivalent and shear stresses, respectively, as well as that of the temperature-dependent interfacial fatigue strength of diamond coatings via the critical shear stress, are shown.
