“…Reported examples of coating systems showing this behaviour include 1 m a-C on Si in nano-scratch testing with a R = 4 m probe [25] and ~0.8 m nc-TiN/a-SiN x on Si in nano-scratch testing with a R = 3 m probe [34]. When micro-scratch testing of hard nitride coatings on cemented carbide the on-load scratch depths do not vary significantly with coating properties but the same trend of higher hardness, H/E and H 3 /E 2 being connected with a lower L c2 is also commonly found [21,[35][36][37].…”

DLC coatings can combine high hardness with low friction. However, they are often deposited with high levels of intrinsic stress and display low adhesion strength resulting in poor performance in demanding applications. A highly topical challenge is to develop advanced DLC coatings capable of withstanding more demanding applications in the automotive, cutting tools, MEMS and oil and gas sectors. The results from several nanomechanical and tribological test techniques -nanoindentation, nano-scratch and nanofretting (nano-wear) -can be used together to aid the design of DLC coating architectures for enhanced durability in specific applications. In this study the behaviour of multilayered DLC coatings (Cr/W-C:H/a-C:H, Cr/W-C:H/Si-a-C:H) was compared to that of CrN/a-C:H:W (WC/C). We have previously reported that in nano-wear tests the coating with the highest hardness and H/E displayed greater wear resistance [T.W. Liskiewicz et al, Surf. Coat.Technol. 237 (2013) 212]. By employing nano-and micro-scale tribological testing with probes of differing sharpness it is possible to change the sensitivity of the test to probe the response of the coating top layer or the entire multilayer coating-substrate system. In the nano-scratch tests using a spherical indenter with a 5 m end radius the maximum stresses are located well within the top layer of the multilayer coatings and consequently the mechanical properties of this top layer dominate the nano-tribological behaviour. In the micro-scratch using a 25 m spherical probe the stress field extends further towards the sublayers and steel substrate and consequently the behaviour is completely different. Under these conditions the coating with the lowest hardness and H/E showed improved performance with higher critical loads for cracking and total coating failure. High resolution SEM imaging has been used to investigate this further. A simple contact model strongly suggests that cracking and failure events occur on the harder coatings when the maximum von Mises stress was located close to the interfaces in the multilayer systems.3

“…Examples include interrupted cutting (milling), contact between valve-train components in internal combustion engines and collisions between air-borne particulates and gas turbine blades [26,27,52,[97][98][99]. The ability to simulate the relevant in-service contact conditions is highly desirable in the development of materials for these applications and the nano-impact technique is increasingly being used for this purpose.…”

“…Test methodologies and data analysis techniques adapted in previous investigations can be categorised in three main areas. The first one is depth sensing as indicated by Beake et al [5][6][7][8][9] where a sudden increase in contact depth vs. time or number of impacts indicate the failure of component or film. The second one is area based calculations as indicated by Bouzakis et al [10][11] where the fracture ratio of failed area and undamaged film indicates film failure.…”
