Laser electrochemical compound deposition (LECD), which introduces a high-energy laser beam into the process of deposition, has advantages higher rate and better machining quality. With multiple-field characteristic coupling LECD, multi-physics simulation software, COMSOL, was selected to perform simulations ascertain influence irradiation on deposition. Here, finite element model LECD established, electric with temperature flow field performed main forms mass transfer were studied. The...
Amorphous Ni-P alloys crystallize at high temperatures, which leads to the deterioration of resistivity and corrosion resistance. In this study, use laser irradiation with electrodeposition (ECD) process for preparing amorphous coatings was investigated; high-temperature crystallization, oxidation resistance, resistance were evaluated. The coating prepared by laser-assisted (LECD) maintained some structure 300 °C, while solely ECD had crystallized completely. With increasing ambient...
Abstract As a nontraditional processing technology, Electrochemical discharge machining (ECDM) can precisely process glass and engineering ceramics. This technology has proven to be potential for 3D microstructure. However, the key expanding application of ECDM is how improve accuracy. research conducted micro-hole microgroove machining. The influence power voltage frequency on hole efficiency, entrance diameter limit depth explored. We considered four factors affecting ECDM–the pulse...

The coating properties obtained in previous studies are time-sensitive. In actual service process, the surface may be contact with air for a long time. Therefore, this study discusses evolution of morphology and corrosion resistance air-exposed coatings prepared by laser-assisted electrodeposition (LECD) (ECD) (LECDed ECDed). results show that amorphous oxidized (20 days, 25 °C) formed micron structure, roughness (Sa) increased one order magnitude. structure LECDed was more uniform, size...
