Christopher Muratore,Christopher Muratore,Jianjun Hu,Jianjun Hu,Baoming Wang,M. A. Haque,John E. Bultman,John E. Bultman,Michael L. Jespersen,Michael L. Jespersen,Patrick J. Shamberger,Michael E. McConney,Rachel D. Naguy,Andrey A. Voevodin +13 more
TL;DR: In this paper, a vapor phase growth technique for precisely controlled synthesis of continuous, uniform molecular layers of MoS2 on silicon dioxide and highly oriented pyrolitic graphite substrates of over several square centimeters at 350°C was described.

TL;DR: In this article, the thermal properties of hexagonal transition metal dichalcogenide compounds with different average atomic masses but equivalent microstructures were compared to bulk crystals, revealing a >10 fold reduction in thin film thermal conductivity.
Journal ArticleDOI
Investigation into three-dimensional laser processing of tribological coatings
TL;DR: In this paper, the authors considered the further evolution of coating design to three dimensions, where the lateral property variation was added to the cross-thickness property variation, which considerably improved the tribological characteristics of hard coatings, by permitting solid lubricant replenishment inside the friction contacts.
Journal ArticleDOI
In situ Raman Spectroscopy for Examination of High Temperature Tribological Processes
TL;DR: In this paper, Raman spectroscopy of solid lubricant coatings during high temperature wear testing was employed for real-time correlation of sliding contact surface chemistry to the measured friction coefficient.
