Characterization of Sintered Hardmetals Coated with Tic
(Universitatea "Dunărea de Jos" din Galaţi, 2013)
This paper presents the realization of TiC thin films by CVD method. The thin
layers of TiC thicknesses were 8 and 10μm, their thickness increasing with time,
keeping the temperature. Diffractometer analysis certifies ...
Laser Cladding of Ni-Cr-B-Fe_Al Alloy on a Steel Support
(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 Surface Hardening of 51Crv4 Steel
(Universitatea "Dunărea de Jos" din Galați, 2005)
The work presents the surface changes in microstructure and properties by
quenching the 51CrV4 steel from liquid and solid phase, using a CO2 continue laser
wave with 900W power. In order to determine the hardening ...
