TL;DR: In this article, the effect of the actual environment (refrigerant) present in hermetic compressors on the tribological behaviour of a Si-rich multifunctional DLC coating deposited on 1020 steel and tested against 52100 steel pins was analyzed.

TL;DR: In this paper, micro-abrasion tests were conducted under constant load and speed conditions while special emphasis was given to the nature of the abrasive; two exogenous (Al 2 O 3 and SiO 2 ) and one endogenous abrasive (Fe 2 O3 ) were used.

TL;DR: In this paper, the wear scars were characterised by Raman spectroscopy and scanning electronic microscopy, to evaluate the evolution of the wear with test time and the composite's tribological properties were evaluated under reciprocating sliding conditions.

TL;DR: In this article, the authors used thermodynamic simulations with DICTRA® to predict the SiC dissociation in the ferrous matrix studied (Fe+0.6C), and compared the characteristics of the graphite nodules, micro-Raman and tribological analyses (friction coefficient and wear rate) for nodular cast iron and graphite powder.

TL;DR: In this article, the authors proposed a new methodology allowing short test time with good discrimination between multifunctional layers, which is based on a method of incremental loading, by increasing the normal load in increments at a constant time interval the surface durability of both the hard layer and the solid lubricant coating was determined.
