Relationship between mechanical properties and structures of zinc dithiophosphate anti–wear films
TL;DR: In this paper, the structure and rheological properties of the antiwear films from a zinc dialkyldithiophosphate (ZDTP) solution generated in a rolling/sliding contact simulating engine valve train conditions were investigated.

A simple guide to determine elastic properties of films on substrate from nanoindentation experiments
TL;DR: In this paper, a model for extracting the intrinsic elastic modulus of thin films from the composite film/substrate modulus value obtained from indentation tests on coated systems is presented.
Understanding the hydrogen and oxygen gas pressure dependence of the tribological properties of silicon oxide–doped hydrogenated amorphous carbon coatings

TL;DR: In this paper, the authors developed a fundamental understanding of the environmental impact on the tribology of silicon oxide-doped hydrogenated amorphous carbons (a-C:H:Si:O).

Determination of mechanical properties by nanoindentation independently of indentation depth measurement
TL;DR: In this article, the authors proposed a new technique based on the detection of the amplitude of the second harmonic was described in a previous paper, which is applicable only to homogeneous materials with constant Young modulus.
Synergistic effects of MoDTC and ZDTP on frictional behaviour of tribofilms at the nanometer scale
TL;DR: In this paper, the layered structure and the rheological properties of anti-wear films, generated in a rolling/sliding contact from lubricants containing zinc dialkyldithiophosphate (ZDTP) and/or molybdenum dialkylfithiocarbamate (MoDTC) additives, have been studied by dynamic nanoindentation experiments coupled with a simple modelling of the stiffness measurements.
