Analysis of Carbon Dioxide Laser Cut Surface Finish on Incoloy 800 Alloy
Abstract-In this study, samples of Incoloy 800 Alloy series plate with the thickness of 1mm was cut using Carbon Dioxide (COZ) laser cutting system with different combination of process parameters such as laser power output, cutting speed and assist gas pressure. The surface roughness tester was used to assess the surface finish of the Incoloy plate after the laser cut. The result of the surfac…

Corresponding Between Local Current And Photovoltaic Performance Of Polycryst…
Undoped polycrystalline Si (poly-Si) photovoltaic thin films prepared by VHF-PECVD on differently textured substrates have been investigated by a conductive scanning probe microscope (SPM) technique. Influences of the substrate texture on the crystal growth as well as the local current flow are discussed. Keywords: Polycrystalline silicon, thin film, crystal growth, textured su…
