Laser Deposition of Bronze Aluminum on Steel Support
(Universitatea "Dunărea de Jos" din Galați, 2015)In order to rise the wear and corrosion resistance of 0.45% C superficial steel layers, a multilayer coating was tested by injection of powder with 88.3% Cu; 9.5% Al; 2.2% Fe in melted bath by CO2 continuous wave laser. ... -
Modification of Surface Properties by Laser Cladding with Ni-Cr-B-Fe-Al Alloy
(Universitatea "Dunărea de Jos" din Galaţi, 2012)The paper is focused on modification of surfaces properties by laser cladding. To follow the corrosion behavior in different media of laser cladding layers made of nickel based alloy Ni - Cr - B - Fe - Al. It was studied ... -
Research Concerning the Influence of Laser Cladding on the Operating Charactersitics of the Surface Layers Obtained from High-Speed Steel Powder
(Universitatea "Dunărea de Jos" din Galați, 2013)The paper presents the corrosion behavior of laser cladding layers in 0.5 M NaCl along with a durability test, compared with samples made of clasically hardened HS6-5-2 steel. The higher characteristics of the laser ... -
Research on Abrasive Wear Behaviour of laser Cladding Lyers with Aluminum Bronze Powders
(Universitatea "Dunărea de Jos" din Galați, 2014)The paper presents the wear behaviour on rotating disk with abrasive paper of laser cladding layers with aluminum bronze powders compared with steel samples and aluminum bronze classically quenched. The hardness and wear ...
