Chapter Introductioning tools. However, the overall efficiency of this new technology is limited, in many instances, by the difficulty of obtaining effective coupling between incident laser radiation and the workpiece. High reflectivity, plasma shielding and gas absorption all conspire to reduce the overall coupling oflipids 发表于 2025-3-31 03:41:23
Laser Material Interactions of Relevance To Metal Surface Treatmentis of available theoretical descriptions of the absorptivity A and its temperature dependence. Experimental coupling coefficients for cw CO. laser radiation on metals over the range 20–1000°C are reported. The effect of oxidation on these coefficients is discussed. Finally, several methods of increa不规则 发表于 2025-3-31 06:42:33
Stimulated Absorption of C02 Laser Light on Metalse of initial surface roughness, which by a stimulated process grows into a coherent periodic corrugation or “ripple” pattern, owing to a nonlinear interaction with surface plasmons. Once developed, this ripple pattern acts as an anti-reflective coating, enabling the full absorption of the incoming r沐浴 发表于 2025-3-31 10:45:14
Characterization of Laser-Induced Plasmas and Temperature Measurement During Laser Surface Treatmentting and vaporization as in laser surface alloying. Due to short dwell times, high temperatures and steep gradients, it is difficult to measure surface temperatures during laser/target interaction. Processes involving vaporization are more complicated to monitor due to the resulting plasma formationGROSS 发表于 2025-3-31 15:18:36

Chapter Introductionn processes in metals and alloys under these unusual conditions is less developed than in the case of silicon. One reason for this, of course, was the perceived technological importance of laser processing of silicon, which led to a broad-based, concentrated study of this problem. Furthermore, many
