Laser shock peening (LSP) of Al2O3 advanced ceramics is reported, showing underpinned physical mechanisms and potential benefits. It known that localised plastic deformation can be induced in the presence a high hydrostatic pressure. therefore interest to apply LSP on large surface areas order create strengthening mechanism. An Nd: YAG laser was used for study at an increment 1 J, 1.5 J 1.7 energy. The treatment characterized using 3-D profiler Cr3+ fluorescence spectroscopy from which...
This paper summarises the regulation mechanism of traditional and emerging surface strengthening treatments – mechanical shot peening (SP) laser shock processing (LSP) treatment, respectively on fretting fatigue behaviour tenon joint materials aero-engine cold-end parts, as treatment contributes to improvement service performance. From point view actual environment turbine components, this also expounds key problems faced by in improving properties for hot-end components. The application LSP...
Vickers hardness indentation tests were employed to investigate the near-surface changes in of a fibre laser-treated and an as-received ZrO 2 engineering ceramic. Indents created using 5, 20, 30 kg loads obtain hardness. Optical microscopy, white-light interferometry, coordinate measuring machine then used observe crack lengths geometry. Palmqvist half-penny median profiles found, which dictated selection group equations herein. Computational analytical approaches adapted determine K 1 c ....
It has been thoroughly demonstrated previously that lasers hold the ability to modulate surface properties of materials with result being utilization such in both research and industry. What is more, these laser treatments have shown affect adhesion characteristics biofunctionality those materials. This paper details use a Synrad CO2 marking system treat nylon 6,6 polytetrafluoroethylene (PTFE). The laser-modified surfaces were analyzed using three-dimensional profilometry ascertain an...
This paper focuses on the evaluation of mechanical and biological properties laser shock peening (LSP) orthopaedic grade Ti-6Al-7Nb alloy. LSP surface treatment was conducted at energy 3 to 7 J with overlaps 33%-67%, a mm spot size. Cell viability peened evaluated through in-vitro MTT assay, using osteoblast-like MG63 cells for first-time. Residual stresses, microhardness, microstructure, sliding wear wetting were investigated. Compressive residual stresses found various depths due...
