XRD studies had revealed that the HiPIMS coating featured lower residual stresses and more fine-grained structure. Electrochemical characterization with the potentiostat-impendence method shows that the HiPIMS coating has a significantly lower porosity than CAD. SEM and AFM studies of the surface morphology demonstrate that the HiPIMS coating has a smoother surface and an absence of droplet phases, in contrast with CAD. XRD, combined with FIB/TEM studies, shows a difference in the crystal structure of both coatings. The micromechanical characteristics of each coating, such as hardness, elastic modulus, fracture toughness, and adhesion to the substrate, were evaluated. The HiPIMS coating was found to possess a more beneficial combination of micromechanical properties compared to CAD. The beneficial characteristics of the HiPIMS coating alleviated the damage of the coated layer under operation. Combined with grain size refinement, this results in the improved adaptive performance of the HiPIMS coating through the formation of a greater amount of thermal barrier sapphire tribo-films on the friction surface. All of these characteristics contribute to the reduction of flank and crater wear intensity, as well as notching, leading to an improvement of the HiPIMS coating’s tool life. 000151648 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttps://creativecommons.org/licenses/by/4.0/deed.es 000151648 590__ $$a3.236$$b2021 000151648 591__ $$aMATERIALS SCIENCE, COATINGS & FILMS$$b9 / 19 = 0.474$$c2021$$dQ2$$eT2 000151648 591__ $$aPHYSICS, APPLIED$$b66 / 161 = 0.41$$c2021$$dQ2$$eT2 000151648 591__ $$aMATERIALS SCIENCE, MULTIDISCIPLINARY$$b201 / 344 = 0.584$$c2021$$dQ3$$eT2 000151648 592__ $$a0.482$$b2021 000151648 593__ $$aSurfaces and Interfaces$$c2021$$dQ2 000151648 593__ $$aMaterials Chemistry$$c2021$$dQ2 000151648 594__ $$a3.9$$b2021 000151648 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000151648 700__ $$0(orcid)0000-0002-1296-4793$$aAguirre, M.H.$$uUniversidad de Zaragoza 000151648 700__ $$aYamamoto, K. 000151648 700__ $$aZhao, Q. 000151648 700__ $$aZhitomirsky, I. 000151648 700__ $$aFox-Rabinovich, G. 000151648 700__ $$aVeldhuis, S.C. 000151648 7102_ $$12003$$2395$$aUniversidad de Zaragoza$$bDpto.
