Performance and wear mechanisms of PCD and pcBN cutting tools during machining titanium alloy Ti6Al4V

, 2020
The need for increased productivity in difficult-to-machine titanium alloys has pushed manufacturers to examine the potential of ultrahard cutting tool materials such as polycrystalline diamond and polycrystalline cubic boron nitride as alternative ...

Wear mechanisms identification using Kelvin probe force microscopy in TiN, ZrN and TiN/ZrN hard ceramic multilayers coatings

, 2020
Mechanical and tribological properties of titanium nitride, zirconium nitride, and (TiN/ZrN)n multilayers were studied to examine the potential of Kelvin probe force microscopy (KPFM) to identify wear mechanisms.

Investigation of wear mechanisms for the rake face of a cutting tool with a multilayer composite nanostructured Cr–CrN-(Ti,Cr,Al,Si)N coating in high-speed steel turning

Wear, 2019
The article considers the wear pattern for the rake face of a cutting tool with the Cr–CrN-(Ti,Cr,Al,Si)N multilayer composite nanostructured coating in turning 1045 steel at vc = 300 m/min. Attention was paid to the diffusion and oxidation processes and

High temperature wear mechanisms in thermally oxidized titanium alloys for engine valve applications

Wear, 2019
Titanium alloys are promising lightweight materials to replace the conventional use of stainless steels in engine valve applications, but their high temperature wear resistance should be improved. In this study, a thermal oxidation (TO) treatment (at 600

Analysis of wear mechanisms of hot forging tools protected with hybrid layers performed by nitriding and PVD coatings deposition

Wear, 2019
This article presents the results of research on hybrid layers used to increase the durability of hot forging tools. The aim of the work is to uniformly compare mechanisms of wear of different hybrid layers deposited simultaneously on one forging tool ...

Microstructure and wear mechanisms of texture-controlled CVD α-Al2O3 coatings

, 2017
In the present study, the microstructure and wear mechanisms of texture controlled CVD alpha-Al2O3 layers with (001), (012) and (100) growth textures were investigated in single point turning of C45 carbon steel at low and high cutting speeds.

Influence of SiC ceramic reinforcement size in establishing wear mechanisms and wear maps of ultrafine grained AA6063 composites

Ceramics International, 2019
This paper described the influence of varying sizes of SiC ceramic reinforcement (coarse (12 μm), fine (1 μm) and nano (45 nm)) in establishing the wear mechanisms and the wear mechanism maps of ultrafine grained (UFG) AA6063/4 wt%SiC composites. The UFG
