EXPERIMENTAL INVESTIGATIONS OF THE Cu-Mo AND Cu-Ti ELECTRO-SPARK COATINGS MODIFIED BY LASER BEAM
The paper is concerned with determining the influence of the laser treatment process on the properties of electro-spark deposited coatings. The properties were assessed by analyzing the coating microstructure, microhardness, residual stresses and corrosion resistance. The tests were conducted for Mo, Ti and Cu coatings (the anode) which were electro-spark deposited over the C45 steel substrate ...
متن کاملCrystallographic texture in pulsed laser deposited hydroxyapatite bioceramic coatings.
The orientation texture of pulsed laser deposited hydroxyapatite coatings was studied by X-ray diffraction techniques. Increasing the laser energy density of the KrF excimer laser used in the deposition process from 5 to 7 J/cm(2) increases the tendency for the c-axes of the hydroxyapatite grains to be aligned perpendicular to the substrate. This preferred orientation is most pronounced when th...
متن کاملLow Friction, High Endurance Ion-Beam Deposited Pb-Mo-S Coatings
Thin solid lubricating coatings of Pb-Mo-S were deposited on steel substrates via ion-beam deposition. Coating endurance and friction coefficients under dry air sliding conditions were monitored with ball-on-disk tests; additional tribological testing was performed using a ball-on-flat reciprocating test rig to investigate intermediate sliding distances (100-32000 cycles). Rutherford backscatte...
متن کاملDiffuse neutron reflectivity and AFM study of interface morphology of an electro-deposited Ni/Cu film
We present a detailed study of the interface morphology of an electro-deposited (ED) Ni/Cu bilayer film by using off-specular (diffuse) neutron reflectivity technique and Atomic Force Microscopy (AFM). The Ni/Cu bilayer has been electro-deposited on seed layers of Ti/Cu. These two seed layers were deposited by magnetron sputtering. The depth profile of density in the sample has been obtained fr...
متن کاملTribological behavior of sputter-deposited MoSX/Ni coatings
AbstractSputtered MoS2 coatings have been mostly used as a solid lubricant. In this investigation, MoSx/Ni composite coatings with Ni contents varying from 0 to 22 % were deposited onto steel substrate using a DC magnetron sputter process. The MoS2/Ni ratio in the coatings was controlled by sputtering the composite targets. The composition, microstructure, and mechanical properties of the...
