The paper demonstrates study results of the processes reactive magnetron sputtering a Ti-Al composite target in an Ar/O 2 gas mixture with various methods supply to chamber. It has been established that, regardless method supply, when changing oxygen concentration mixture, ratio Al and Ti content deposited 1-x x O y films changes. metal varies proportion change control lines intensities optical...

This research was to prepare the titanium dioxide nanotube arrays (TiNT arrays) and deposit the Au nanoparticles on its surface using the pulse electrodeposition technique. The Au nanoparticles-TiNT arrays (AuNP-TiNT arrays) were characterized by field emission scanning electron microscopy (FESEM), X-ray diffraction, and cyclic voltammetry. The results showed that the Au nanoparticles were unif...

Technological mineralogy of titanium ores is the basis for assessing their complexity. It enables, from a unified standpoint, to trace entire course changes in mineral matter through operating procedures, including beneficiation, processing, and obtaining target industrial products. The study targets are Pizhemskoye ilmenite-leucoxene sandstones, which distinguished by complex polymineral compo...

Scanning electron microscopy, 3D optical surface profilometry, as well X-ray diffraction and backscatter analysis were implemented for studying the effects of both ultrasonic impact treatment (UIT) electrospark (UIET) procedures on microstructure, phase composition, mechanical tribological properties Ti-6Al-4V samples fabricated by wire-feed beam additive manufacturing. It was shown that he UIE...

In this paper an effect of capsule-free hot isostatic pressing (HIP) on the porosity and mechanical properties different cold spray deposits was experimentally evaluated. The HIP post-treatment significantly decreased (more than 2 times) 316L pure titanium deposits. densification porous Ti6Al4V deposit less pronounced. Mechanical after were also improved. particular, tensile strength stainless ...

Informal lending and savings institutions exist around the world, and often include regular door-to-door deposit collection of cash. Some banks have adopted similar services in order to expand access to banking services in areas that lack physical branches. Using a randomized control trial, we investigate determinants of participation in a deposit collection service and evaluate the impact of o...
