Laser-induced liquid-phase jet-chemical etching of metals
In this treatment method laser radiation, which is guided from a co-axially expanding liquid jet-stream, locally initiates on a metal surface a thermochemical etching reaction, which leads to selective material removal. Time-resolved measurements of the electrical potential were correlated with the specific processing parameters to identify conditions for stable and enhanced chemical etching re...
متن کاملChemical etching characteristics for cellulose nitrate
Cellulose nitrate films (commercially available as LR 115 films were irradiated systematically with alpha particles in the energy range from 1 to 5 MeV with incident angles from 30◦ to 90◦. After etching to remove a thickness of 6.5 m, the lengths of the major and minor axes of the alpha-particle track openings in the films were measured with an image analyser under an optical magnification of ...
متن کاملFabrication and Optical Characterization of Silicon Nanostructure Arrays by Laser Interference Lithography and Metal-Assisted Chemical Etching
In this paper metal-assisted chemical etching has been applied to pattern porous silicon regions and silicon nanohole arrays in submicron period simply by using positive photoresist as a mask layer. In order to define silicon nanostructures, Metal-assisted chemical etching (MaCE) was carried out with silver catalyst. Provided solution (or materiel) in combination with laser interference lithogr...
متن کاملEffect of hydrofluoric acid concentration and etching time on the surface roughness of CAD/CAM ceramics
Introduction: Dental ceramics are considered as materials that can restore the appearance of natural teeth. Etching the inner surface of a ceramic restoration with hydrofluoric acid (HF) followed by using a silane coupling agent is a well-known and recommended method to increase the bond strength. The aim of etching on ceramic structure is to enhance the surface roughness (Ra) and energy and to...
متن کاملTitle: Hardness Determination of Bio-ceramics Using Laser-induced Breakdown
Laser-Induced Breakdown Spectroscopy (LIBS) was applied to the analysis of bioceramic samples. The relationship between sample hardness and LIBS plasma properties was investigated, with comparison to conventional Vickers hardness measurements. The plasma excitation temperature Te was determined using the lineto-continuum ratio for the Si (I) 288.16 nm emission line; we have demonstrated a linea...
