Journal ArticleDOI
Microstructural design of hard coatings
TL;DR: In this article, the authors demonstrate the correlation between microstructure and mechanical as well as tribological properties of hard ceramic coatings and demonstrate that nanostructure dependent hardness increase (compared to hardness of the bulk counterparts) sustains higher annealing temperatures than hardness increase due to an increased density of point-and/or line-defects.
Journal ArticleDOI
Self-organized nanostructures in the Ti–Al–N system
Paul H. Mayrhofer,Anders Hörling,Lennart Karlsson,Jacob Sjölén,Tommy Larsson,Christian Mitterer,Lars Hultman +6 more
TL;DR: In this paper, a model system, Ti1-xAlxN, was chosen as such coatings are known for their excellent wear resistance enabling improved m... and the phenomenon of age hardening could be evidenced in thin film applications.
Journal ArticleDOI
Thermal stability of Al-Cr-N hard coatings
Herbert Willmann,Paul H. Mayrhofer,Paul H. Mayrhofer,Per Persson,Per Persson,A.E. Reiter,Lars Hultman,Lars Hultman,Christian Mitterer +8 more
TL;DR: In this article, the authors investigated the reaction of arc-evaporated cubic Al0.7Cr0.3N hard coatings in Ar up to 1450 °C.
Journal ArticleDOI
Microstructure and mechanical/thermal properties of Cr–N coatings deposited by reactive unbalanced magnetron sputtering
TL;DR: In this article, the influence of nitrogen/argon flow rate ratio, ion energy and ion/atom flux ratio on the microstructure, hardness, residual stresses and thermal stability of magnetron sputtered chromium nitride coatings was reported.
Journal ArticleDOI
A comparative study on reactive and non-reactive unbalanced magnetron sputter deposition of TiN coatings
TL;DR: In this paper, the differences of the ion bombardment parameters for non-reactive and reactive sputtering of TiN coatings have been studied in detail, and an explanation of the high hardness values of the coatings is given and the influence of thermal annealing on the defect density, grain size and microhardness is presented and discussed in detail.
