“…This additional load is introduced into the coating besides Fn, which is almost as high as F and almost constant between 0 8 and 10 8 inclination. Comparing to other reported results in literature [12][13][14][16][17] it can be noted, that endured loads until damage are here considerably higher. There are two possible reasons for this behavior.…”

“…This might especially be a drawback when the surface is exposed to high loads, as it is done here. To provide a better adhesion, the polished cutting inserts have been micro-blasted prior to the deposition process, since Bouzakis et al have shown in [13] that polished and micro-blasted specimens provide the best performance under inclined impact loads. As it can be seen in Figure 2 coatings show a very good adhesion.…”

“…The impact tests were conducted in a test rig which was developed by the Laboratory of Machine Tools and Manufacturing Engineering of the Aristoteles University of Thessaloniki in conjunction with CemeCon AG. Detailed Information about the test rig can be found in [12][13][14]. During impact testing samples were positioned at different angles under the impact head with respect to the normal load direction, as it is shown in Fig.…”

Over the last decade the interest in High Power Pulse Magnetron Sputtering (HPPMS) and High impulse Magnetron Sputtering (HiPIMS) has undergone a considerable increase. This is mainly due to the fact that several researchers have shown that in these processes a distinct increase of the ionization of deposition species is observable. However, there is only little known about the performance of these films with regard to applications. Recently Hovsepian et al. [1] and Bobzin et al. [2] presented cutting results of different films. Both authors show that films deposited using HPPMS or HiPIMS outperform state-of-the-art coatings. Depending on the cutting process, besides hardness and adhesion also excellent impact behavior is required. Therefore this work deals with the impact behavior of (Ti,Al,Si)N which was deposited using HPPMS for the application in interrupted cutting process. The impact behavior of HPPMS coating under normal and tangential loads is analyzed. During impact tests number of impacts, loads and inclination angle of the samples with regard to the load direction are varied. (Ti,Al,Si)N shows an excellent endurance even at very high loads causing Hertzian stresses in the range of 10 -13 GPa. At an inclination angle of 10 8 and an impact load of 100 N, which corresponds to app. 10 GPa initial Hertzian stress, no damage was observed after 800610 3 impacts.

“…No cracks or any significant detachments appeared in these imprints, indicating a good film adhesion. Since this test does not always reveal adhesion problems [5] and moreover, it cannot quantify the adhesion, inclined impact tests were further conducted.…”

“…Substrate pre-treatments and adhesive layers are often used for enhancing the films' adhesion [3,4]. The coatings' adhesion control by scratch or by Rockwell indentation tests after VDI 3198/92, does not always yield to definite and quantitative results [5]. The quantification of the coating mechanical properties and adhesion is usually a difficult task.…”

In some industrial situations, components are subject to repetitive impact in the presence of a slurry. A novel repetitive impact-with-slurry test rig was developed to evaluate the behaviour of a wide range of engineering materials in such conditions. The test materials could be categorised into five main groups – heat treated steels, stainless steels, chromium cast irons, hardfacing coatings and superalloys. Three-dimensional surface topography was used to quantify the depths and volumes of the produced wear scars. Post-test metallurgical examination was also conducted to further evaluate the wear processes. The wear mechanisms could be split into two main groups of materials; ductile materials were observed to plastically deform and hard/brittle materials demonstrated cracking/spalling mechanisms. Hardened martensitic-type materials exhibited the greatest resistance to repetitive impact wear.
