Mechanical and tribological properties of Cr–N and Cr–SI–N coatings reactively sputter deposited

Influence of Oxygen Contents on the Microstructure, High Temperature Oxidation and Corrosion Resistance Properties of Cr–Si–O–N Coatings

“…CrN has been one of the most extensively used hard coatings for various forming and casting applications [1,2], due to its excellent high-temperature oxidation resistance and good corrosion resistance [3,4]. In recent years, efforts have been continuously devoted in order to further improve the properties of CrN coatings.…”

Solid particle erosion mechanisms of protective coatings for aerospace applications

“…It has been found that the addition of other elements such as silicon (Si) in MeN systems can have profound effects on their mechanical, chemical and tribological properties [11,14,[221][222][223][224][225]. These changes have been explained by two main mechanisms: the formation of a nanocomposite microstructure formed by the segregation of MeN grains separated by a monolayer thick SiN x matrix [14,221,223] and solid solution hardening [11,222] due to the substitution of Me atoms by Si in the MeN lattice.…”

“…While Mercs et al [223] proposed a nanocomposite hardening mechanism, Martinez et al [222], and more recently Benkahoul et al [11], proposed that hardening is better explained by a solid solution mechanism. In fact, the different studies find that maximum hardness is obtained for silicon concentrations (C Si ) varying from 2 to 10 at.%.…”

Structure and mechanical properties of reactive sputtering CrSiN films

“…However, there is still a dispute on the effects of Si addition to MeN on the bonding structure, crystalline structure and texture of the nanocomposite MeSiN films. The previous investigations on CrSiN films lack systematic research on the microstructural and mechanical properties by addition of Si [11,7,[15][16][17][18][19]. The knowledge and characterization of these parameters are import to understand both the process involved in the preparation and the future behavior of such films.…”
