Laser Forming of Mild Steel Sheets Using Different Surface Coatings,ically, experimentally, and numerically. Effect of almost all the parameters—geometric, material and energy—affecting the shape of final product have been studied at length. Some experimental studies have been carried out using surface coating like graphite on the face of the sheet where the laser i只有 发表于 2025-3-23 22:58:11

Effect of Pulsed Nd:YAG Laser Parameters in Preplaced TiC Coating on Aluminium Substrate,w successful formation of coating. Experimental results also show that, increase in laser peak power and pulse overlapping increases the coating thickness. High peak power results in removal of coating material but produces TiC mixed Aluminium layer at the top surface of substrate. Micro-hardness pr阻塞 发表于 2025-3-24 08:02:31
Excimer Laser Micromachining and its Applications,dia was studied using 248 nm KrF excimer laser. The effect of gas purging on the ablation rate and surface characteristics of the polymer was studied. Amongst the gases used, hydrogen gas showed distinct results with respect to ablation rate and surface characteristics. It has been observed that hydCorral 发表于 2025-3-24 13:48:47
