Nanocomposite and nanostructured tribological materials for space applications
TL;DR: In this paper, a chameleon tribological coating concept was developed to address the challenge of degradation of lubricants and excessive wear in space-terrestrial environments. But, this approach relies on the coating to change its surface (both chemistry and structure) to self-adjust to the environment and thus achieve long durability.

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.

Attempt to design a strong solid.
TL;DR: In this paper, it was shown that by using alternate layers of materials with high and low elastic constants resolved shearing stresses of the order of ε( √ n ϵ(n 2 ) −1 −1/n −1 )$ will be required in order to drive dislocations through the combination.

A simple model for the formation of compressive stress in thin films by ion bombardment
TL;DR: In this paper, a simple model was proposed to explain the formation of compressive stress in thin films deposited with simultaneous bombardment by energetic ions or atoms, and it was shown that the stress σ is proportional to [ Y (1-v) ]E 1 2 (R j+kE 5 3 ), where E is the ion energy, R the net depositing flux, j the bombarding flux, k a material dependent parameter, Y the film material Young's modulus and v the Poisson ratio.

Model of superlattice yield stress and hardness enhancements
X. Chu,Scott A. Barnett +1 more
TL;DR: In this article, a model that explains the yield stress and hardness enhancements that have been observed in superlattice thin films was presented, where the stress required for dislocations to glide across layers with different shear moduli was calculated using an expression that accounts for core effects and all interfaces in trapezoidal or sawtooth composition modulations.

Multilayer PVD coatings for wear protection
H. Holleck,V. Schier +1 more
TL;DR: In this paper, a functional and a structural design, taking into account the material selection for the individual layers, the adjustment of the interface volume and constitution and the optimization of the individual layer sequence and thickness, allows a tailoring of properties and performance.
