Influence of Ultrasonic Nanocrystalline Surface Modification on the Microstructure and Mechanical Properties of Laser-Welded Butt Joints of AISI 304 Austenitic Stainless Steel

This study investigated the effect of Ultrasonic Nanocrystalline Surface Modification (UNSM) on the microstructure, local mechanical properties, surface condition, and tribological behavior of a laser-welded butt joint of AISI 304 austenitic stainless steel. Laser welding was performed using ER308LSi filler wire at app...

Impact of HVOF Regimes on the Structure, Phase Composition, and Mechanical and Tribological Properties of 86WC–10Co–4Cr Coatings

The aim of this work is to investigate the influence of high-velocity oxygen-fuel spraying (HVOF) process regimes on the microstructure, phase composition, and mechanical and tribological properties of 86WC–10Co–4Cr coatings on a 12Kh18N10T stainless steel substrate. The coatings were formed under three HVOF spraying r...

Development of a Method for Producing Self-Fluxing Nickel-Based Coatings by Detonation Spraying

This study investigated the influence of detonation spraying parameters on the structure and tribological and mechanical properties of self-fluxing coatings of the Ni–Cr–Fe–B–Si–C system. The investigated parameters included the barrel filling level (48–68%), the molar ratio of the working gases (O/C = 1.026–1.856), an...
