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.

Compatibility between tribological surfaces and lubricant additives—How friction and wear reduction can be controlled by surface/lube synergies
TL;DR: In this paper, the authors reviewed the recent trends in materials technology and lubricant additive technology in engines and discussed the implications for boundary lubrication in the next decade and the extent to which materials and lubricants are being used in partnership in engineering systems.

Sputtering Physical Vapour Deposition (PVD) Coatings: A Critical Review on Process Improvement and Market Trend Demands
Andresa Baptista,Francisco Silva,Jacobo Porteiro,José Luis Míguez,Gustavo Adolfo Saavedra Pinto +4 more
TL;DR: In this paper, a review of the improvements already studied in order to optimize the sputtering PVD process, trying to relate these improvements with the industrial requirements as a function of product development and market demand is presented.

Effects of the ratio of hardness to Young’s modulus on the friction and wear behavior of bilayer coatings
Wangyang Ni,Yang-Tse Cheng,Michael J. Lukitsch,Anita M. Weiner,Lenoid C. Lev,David S. Grummon +5 more
TL;DR: In this article, the effects of the ratio of hardness to Young's modulus on the friction and wear behavior of layered composite coatings were studied and it was shown that a low friction coefficient and high wear resistance can be achieved in structures with high ratio of hardness to Youngs modulus and moderately high hardness.

An improved technique for determining hardness and elastic modulus using load and displacement sensing indentation experiments
Warren C. Oliver,George M. Pharr +1 more
TL;DR: In this paper, the authors used a Berkovich indenter to determine hardness and elastic modulus from indentation load-displacement data, and showed that the curve of the curve is not linear, even in the initial stages of the unloading process.
Journal ArticleDOI
The Tension of Metallic Films Deposited by Electrolysis
TL;DR: It is well known that metallic films deposited electrolytically are in many cases liable to peel off if deposited to any considerable thickness as discussed by the authors, especially if it does not adhere very tightly to the body on which it is deposited.
Journal ArticleDOI
Mechanical properties of thin films
TL;DR: In this paper, it is shown that very large stresses may be present in the thin films that comprise integrated circuits and magnetic disks and that these stresses can cause deformation and fracture to occur.

A concept for the design of novel superhard coatings
S. Vepřek,S. Reiprich +1 more
TL;DR: In this article, a concept for the design of novel nanocrystalline/amorphous composites is suggested based on recent theoretical and experimental results regarding the appearance of supermodulus phenomena in composition-modulated layered heterostructures and on a simple thermodynamic criterion for segregation in ternary nitride systems.

Growth of single-crystal TiN/VN strained-layer superlattices with extremely high mechanical hardness
TL;DR: In this paper, single-crystal TiN/VN strained-layer superlattices with layer thicknesses ranging from 0.75 to 16 nm have been grown on MgO(100 ) substrates by reactive magnetron sputtering and cross-sectional transmission electron microscopy (TEM) and x-ray diffraction examinations showed that the films were single crystals exhibiting coherent interfaces and several orders of super-lattice reflections.
