Laser Cladding of Ni-Cr-B-Fe_Al Alloy on a Steel Support
Levcovici, Sanda Maria; Levcovici, Dan Teodor; Gheorghieș, Constantin; Boiciuc, Simona (Universitatea "Dunărea de Jos" din Galați, 2005)Multilayer coating by injection of powder with 8.9% Cr, 4.5% Fe, 5.1% B, 2.4% Al, 0.6% Cu; all reminded of Ni, as chemical composition, in melted bath by CO2 continuous wave laser connected to x-y-z coordinate table was ... -
Laser Deposition of Bronze Aluminum on Steel Support
Boiciuc, Simona (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. ... -
Reasearches Regarding Structural Changes Due to Nickel Microlalloying of Hot Galvanizing Baths
Boiciuc, Radu; Preda, Adriana; Boiciuc, Simona (Universitatea "Dunărea de Jos" din Galați, 2005)This work offers a synthesis of researches performed in laboratory and regards the nickel microalloying of hot galvanizing baths. Experiments followed the structural changes of both hot galvanizing bath and deposed layer ... -
Research Concerning the Influence of Laser Cladding on the Operating Charactersitics of the Surface Layers Obtained from High-Speed Steel Powder
Boiciuc, Simona (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
Boiciuc, Simona (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 ... -
