Cyclic nanoindentation and nano-impact fatigue mechanisms of functionally graded TiN/TiNi film

Faisal, N. H.; Prathuru, Anil K.; Goel, Saurav; Ahmed, R.; Droubi, M. G.; Beake, Ben D.; Fu, Y. Q. (Springer, 2017-03-09)

The mechanisms of nanoscale fatigue of functionally graded TiN/TiNi films have been studied using multiple-loading cycle nanoindentation and nano-impact tests. The functionally graded films were sputter deposited onto ...
Designing nanoindentation simulation studies by appropriate indenter choices: Case study on single crystal tungsten

Goel, Saurav; Cross, Graham; Stukowski, Alexander; Gamsjäger, Ernst; Beake, Ben D.; Agrawal, Anupam (Elsevier, 2018-06-22)

Atomic simulations are widely used to study the mechanics of small contacts for many contact loading processes such as nanometric cutting, nanoindentation, polishing, grinding and nanoimpact. A common assumption in most ...
Elevated temperature micro-impact testing of TiAlSiN coatings produced by physical vapour deposition

Beake, Ben D.; Bird, Andrew; Isern, Luis; Endrino, José L.; Jiang, Feng (Elsevier, 2019-06-08)

A high temperature micro-impact test has been developed to assess the fracture resistance of hard coatings under repetitive dynamic high strain rate loading at elevated temperatures. The test was used to study the temperature ...
Elevated temperature repetitive micro-scratch testing of AlCrN, TiAlN and AlTiN PVD coatings

Beake, Ben D.; Endrino, José L.; Kimpton, Christine; Fox-Rabinovich, German S.; Veldhuis, Stephen C. (Elsevier, 2017-08-24)

In developing advanced wear-resistant coatings for tribologically extreme highly loaded applications such as high speed metal cutting a critical requirement is to investigate their behaviour at elevated temperature since ...
Incipient plasticity in tungsten during nanoindentation: Dependence on surface roughness, probe radius and crystal orientation

Beake, Ben D.; Goel, Saurav (Elsevier, 2018-04-04)

The influence of crystallographic orientation, contact size and surface roughness effects on incipient plasticity in tungsten were investigated by nanoindentation with indenters with a range of end radius (150, 350, 720 ...
Influence of probe geometry in micro-scale impact testing of nano-multilayered TiAlCrN/NbN coatings deposited on WC-Co

Beake, Ben D.; Bergdoll, L.; Isern, Luis; Endrino, José L.; Fox-Rabinovich, German S.; Veldhuis, Stephen C. (Elsevier, 2020-11-15)

Hard nano-multilayered TiAlCrN/NbN coatings on cemented carbide have shown promise in dry high speed machining applications involving repetitive contact, such as end milling of hardened H13 steel. In this study the fracture ...
Micro-impact testing of AlTiN and TiAlCrN coatings

Beake, Ben D.; Isern, Luis; Endrino, José L.; Fox-Rabinovich, German S. (Elsevier, 2018-11-23)

A novel micro-scale repetitive impact test has been developed to assess the fracture resistance of hard coatings under dynamic high strain rate loading. It is capable of significantly higher impact energies than in the ...
Micro-scale impact resistance of coatings on hardened tool steel and cemented carbide

Beake, Ben D.; Isern, Luis; Endrino, José L.; Liskiewicz, T. W.; Shi, X. (Elsevier, 2020-11-12)

Micro-impact, a novel accelerated test method for assessing coating durability under repetitive contact, has been developed to concentrate impact-induced stresses close to the interfaces in coating systems. Test results ...
Nano- and micro-scale impact testing of zirconia, alumina and zirconia-alumina duplex optical coatings on glass

Beake, Ben D.; Isern, Luis; Bhattacharyya, Debabrata; Endrino, José L.; Lawson, Ken; Walker, Trevor (Elsevier, 2020-10-06)

Optimising the mechanical properties of optical coatings to improve their durability will be critical if they are to be used successfully in harsh environments where they may be subject to degradation by mechanical contact. ...
Probe geometry and surface roughness effects in microscale impact testing of WC-Co

Beake, Ben D.; Isern, Luis; Harris, A. J.; Endrino, José L. (Taylor & Francis, 2020-05-25)

Depth-sensing repetitive microimpact tests have been performed on cemented carbide cutting tool inserts with spheroconical diamond probes with end radii of 8, 20 and 100 µm. Results were strongly dependent on the probe ...
