When the laser beam hits the material surface, it is absorbed, reflected, refracted, scattered, or transmitted. These interactions result in heating, melting, vaporization, or plasma formation. In laser-cladding processes, one or more of the mentioned phenomena may occur during the process, ...
As represented in Figure 2, in this part, the specimens were hung from a frame using two screw eyes and fishing lines to simulate the free-free condition. A Brüel & Kjær modal exciter type 4824 excited the specimens with a periodic chirp signal between the frequency range of 5 to ...
A high power laser beam may be directed onto a surface using very precise multi-axis handling systems. A laser makes it possible to achieve extremely localized heating areas, remaining the bulk of the workpiece at the lower temperatures. The low temperature mass of the workpiece act as a heat...
Furthermore, DMS has an odor threshold value that varies from 0.6 to 40 ppb (parts per billion) between different persons and it is highly flammable and irritant to eyes and skin Sensors 2018, 18, 3216; doi:10.3390/s18103216 www.mdpi.com/journal/sensors Sensors 2018, 18, 3216 2 of 13...
