A solid-phase diffusion welding of coarse-grained and ultrafine-grained (UFG) specimens titanium near-α alloy Ti-5Al-2V used in nuclear power engineering was made by Spark Plasma Sintering. The failure the welded conditions hot salt corrosion electrochemical shown to have a preferentially intercrystalline character. In case presence macrodefects, crevice joints observed. resistance alloys again...

For corrosion-resistant layer formation, a method using only hot water under atmospheric pressure has been developed. A was obtained with shot peening treatment sodium bicarbonate media as pre-process that is activation by formation of plastic strain on the surface.

The research results of the microstructure and corrosion resistance Ti Ti-Al-V Russian industrial titanium alloys obtained by spark plasma sintering (SPS) are described. Investigations microstructure, phase composition, hardness, tensile strength, electrochemical hot salt alloy specimens were carried out. It was shown that have a uniform highly dense high hardness values. studied also to during...

Abstract: This research examines the performance of strengthened non-uniformly corroded reinforced self-consolidating concrete (SCC) members. This paper focuses on three aspects of concrete including corrosion, concrete cover loss, and repair technique. Up to a 50% corrosion level is considered in this study. Corrosion was experimentally induced and was simulated in other cases. Twenty-six rein...

The stability of an electrodeposited nanocrystalline Ni-based alloy coating in a H₂S/CO₂ environment was investigated by electrochemical measurements, weight loss method, and surface characterization. The results showed that both the cathodic and anodic processes of the Ni-based alloy coating were simultaneously suppressed, displaying a dramatic decrease of the corrosion current density. The co...
