Web1 de mar. de 2024 · 1. Introduction. Laser-produced plasmas (LPP) are formed by a high-power laser pulse focused on a solid target surface. The material in the focus area is heated and evaporated to form a high-temperature high-density vapor that includes atoms, ions, and free electrons during laser ablation stage. WebIncrease in the laser energy density can raise the temperature of the polymer binder, making its viscosity decreased, and thus, the sintering rate is improved, the wetting, …

Web13 de abr. de 2024 · The high-pressure carbon phases beyond diamond are elusive, though, making their discovery a challenge. For example, the first “superdense” post-diamond carbon phase, called BC8, exists only in theory. Research dating back to the 1980s suggests that under extreme pressure, diamond can transform to BC8, which has even … Web7 de fev. de 2001 · A high-energy-density laser beam-material interaction process has been simulated considering a self-evolving liquid-vapour interface profile. A mathematical … Web18 de dez. de 2024 · Near-infrared lasers, which are mainly used in the SLM (selective laser melting) method at present, have a low absorption rate for copper, making it difficult to fabricate a 3D structure of copper. To solve this problem, we have developed a new 200 W blue diode laser (wavelength: 450 nm), that has a high absorption rate for copper. how to search acronyms in word
