Abstract. The main objective of the present work was to determine influence laser beam processing (LBP) on microstructure, microhardness, roughness, and corrosion resistance coatings produced C45 carbon steel by electro-spark deposition (ESD) process. studies were conducted using WC-Co electrodes Pulse Plasma Sintering method (PPS) nanostructural powders. deposited means EIL-8A they treated wit...

The article presents the results of X-ray diffraction studies phase composition, substructure, and residual stresses in surface layer AK5M7 alloy for different energy levels during electric-spark alloying (ESA) using a copper electrode. micro-distortion values were estimated from parameters crystal lattice grains which reflection planes are parallel to sample surface. Three phases, i. e., alumi...

Binary Al-5M alloys, containing 5 at.% alloying element (M: Cr, Si, Nb, Mo, and V), have been produced by high-energy ball milling subsequent spark plasma sintering. X-ray diffraction analysis indicated the solid solubility of elements to be several orders magnitude higher than that predicted phase diagram. The elastic modulus hardness analyzed using nanoindentation, were significantly commerci...

Electrochemical spark machining (ECSM) is hybrid machining process which is the controlled removal of metal by anodic dissolution as well as erosion in an electrolytic cell in which the workpiece is the anode and the tool is cathode. The experimental investigation with the developed TW-ECSM set-up has been needed to understand the behaviour of the process parameters on performance characteristi...
