A PM approach is investigated in the context of extremely fine low temperature bainitic steels with a reasonable combination of ultimate tensile strength and uniform elongation. The strategy consists of three steps. First, ball milling is used for mechanical alloying and to create a large density of interfaces prior to sintering. In the second step, spark plasma sintering is used as a rapid con...

Problem. Electro-spark alloying (ESA) is a promising process of surface modification, which allows obtaining high-quality coating, environmentally safe and energy efficient. Wide application in production hindered by the need to develop technology, as well lack mathematical model for predicting properties coatings depending on materials processing modes. It known that high adhesive bond obtaine...

In this work, the features of phase composition, structures, and properties coatings obtained on a high-speed steel substrate (steel R6M5) were studied. The prepared using ESA method (electro-spark alloying). Electrode materials through self-propagating high-temperature synthesis (SHS) based (Ti-B-Fe)xAlN with addition nanosized AlN particles in amount x = 0.5, 10, 15 wt % used as electrodes. s...

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 ...

The electrocatalytic properties for electro-oxidation reactions of shape-controlled Pt-based catalysts have been improved by alloying with 2nd elements. In this study, we demonstrate cubic PtPd alloy nanoparticles synthesized using a thermal decomposition method. The cubic PtPd nanoparticles exhibit a homogeneous distribution of alloy nanostructures in the presence of Pt and Pd metallic phases....
