Enhancement of Wet- and MQL-Based Machining of Automotive Alloys Using Cutting Tools with DLC/Polymer Surface Treatments
TL;DR: In this article, a tooling prepared with thin perfluoropolyether (PFPE) lubricant films, which were applied to diamond-like carbon (DLC) PVD coatings, was compared to traditional tooling used in wet-machining conditions for the drilling of a cast aluminum-silicon B319 alloy.

Why can TiAlCrSiYN-based adaptive coatings deliver exceptional performance under extreme frictional conditions?

TL;DR: The nanomechanical properties of the underlying coating layer provide a stable low wear environment for the tribo-films to form and regenerate so it can sustain high temperatures under operation (600 degrees C), which explains the high wear resistance of the multilayer TiAlCrSiYN/TiAICrN coating under extreme operating conditions.

TL;DR: In this paper, the changes of structure and properties of the treated coating surfaces have been analyzed using both cross-sectional scanning electron microscopy (SEM) and x-ray absorption spectroscopy (XAS) of the N-K and O-K edges.

Tribofilm Formation As a Result of Complex Interaction at the Tool/Chip Interface during Cutting

TL;DR: In this paper, the authors discussed the thermodynamic aspects of tribofilm formation at the cutting tool/chip interface and showed that there are two types of tribomorphs that affect the wear behavior of a cutting tool: (1) tribofomorphs forming as a result of the surface modification of the cutting tools with further tribo-oxidation; and (2) material transfer from the contacting frictional body (the workpiece) during the tool and chip interaction.

Improvement of Wear Performance of Nano-Multilayer PVD Coatings under Dry Hard End Milling Conditions Based on Their Architectural Development
Shahereen Chowdhury,Ben D. Beake,Kenji Yamamoto,Bipasha Bose,Myriam H. Aguirre,German S. Fox-Rabinovich,Stephen C. Veldhuis +6 more
TL;DR: In this article, a few different coating architectures (monolayer, multilayer, bi-multilayer with increased number of alternating nano-layers) were studied in relation to cutting-tool life.
