摘要:The effect of non-deformable submicron second-phase particles ( d = 200-500 nm) on microstructural refinement during cold spray was examined. Using single particle impact testing, two types of splats were fabricated using two different feedstocks: a Cu-0.21wt.%O powder containing...

摘要:Abstract(#br)Unconstrained high pressure torsion (HPT) tests were performed on two cold-sprayed Al-Al₂O₃ composites, one with spherical Al₂O₃ particles and the other with angular. Derivation of stress-strain curves during HPT revealed higher von Mises stress in the sphe...

摘要:Abstract(#br)The tribocorrosion behavior of SAF 2507 (UNS S32750) superduplex stainless steel exposed to heat treatments at 800 °C was examined in 0.6 M NaCl and in deionized water. Heat treatment induced the growth of secondary phases including sigma phase, secondary austen...

摘要:Abstract(#br)Particle-reinforced aluminum matrix composites (Al-MMCs) generally exhibit lower wear rates and more stable friction than their un-reinforced matrix materials. Cold spray is a popular consolidation route for Al-Al2O3, allowing for its application as a coating for cor...

摘要:Abstract(#br) Reciprocating sliding wear experiments were conducted on cold-sprayed pure aluminum and Al–22.6 wt% Al 2 O 3 coatings using a custom-built in situ tribometer. Using a transparent sapphire counterface for the wear tests, the dynamic behavior of third body materi...

摘要:Abstract(#br)Two cold spray coatings, one pure Cu and the other a Cu–MoS2 composite coating, were studied for their tribology performance in dry air. It was demonstrated that a small amount of MoS2 (1.8 ± 0.99 wt%) could significantly decrease coefficie...

摘要:In this study, “within the environment” and “within the contact” in situ tribology techniques are combined in order to study the interfacial processes in lubricated metallic (i.e., aluminum-based) sliding conditions. The evolution of the roughness follows the trend of t...
