Process of electrochemical deposition the coating based on a binary nickel-molybdenum alloy onto nickel substrate under pulse mode with current reverse within range density change from 2 to 9 A/dm2 has been researched. Coating structure and its surface morphology have studied. Method X-ray energy dispersive spectroscopy determined percentage ratio components in coating. Mode obtain densest smoothest deposits identified considered terms.
Metal nanopowders have a stimulating effect on the growth and development of plants. The biological activity nanoparticles depends size, concentration, chemical composition. Nanoparticles require further study because they wide range applications in medicine agriculture. Being biocompatible, copper cobalt can play role stimulant, are not toxic be used for contact with living systems. object was rice, as an economically important culture. addressed germination rice seedlings. optimal...
The erosion model of the surface coatings reed switches considering different physicochemical processes occurring on contact surfaces and inside inter-electrode gap was proposed. According to that, discrete electron avalanche (ecton) introduced in explosive emission theory by Mesyats is considered as main motive force responsible for modification mass transfer materials course breaking/shorting contacts. By means SEM imaging energy dispersive X-ray microanalysis after various numbers...
The present paper has represented results of researches the electrodeposition Ni-W coatings having a gradient structure. determined conditions synthesis providing possibility to control W content in coating within wide ranges (from 3.3 9.2 at. %). Influence current density and pH value on characteristics been studied. Morphological have researched.
