Micro-structural refinement and tribological enhancement of inconel X-750 superalloy through surface mechanical attrition treatment

Structure and wear resistance of hot-rolled Fe–Cr–B coatings

Introduction. Austenitic steels are widely used in mining, railway, and chemical industries due to their high toughness and corrosion resistance. However, their service life under severe wear conditions is limited, which necessitates the development of effective surface hardening techniques that preserve the ductility...

Effect of Varying Austenitizing Temperatures on Carbide Reduction and Mechanical Properties of Annealed Thin Wall Ductile Iron

Effects of Deposition Parameters on the Microstructural Evolution and Mechanical Properties of TiN Coatings on 7075-T6 Aluminum Alloy

The 7075-T6 aluminum alloy exhibits excellent specific strength due to the presence of precipitated η′ phase, but its surface mechanical performance under demanding conditions is often limited. In this study, a horizontal cylindrical magnetron sputtering system was used to deposit TiN coatings on the surface of 7075-T6...

Process-Microstructure-Property Correlation in Vacuum Sintered Al-Al2O3Functionally Graded Pellets

Aluminum-alumina (Al-Al2O3) functionally graded materials are attractive for components requiring a compliant metallic base and a hard ceramic rich surface. However, their performance is strongly limited by transition layer porosity and incomplete densification during low temperature powder metallurgy. In this study, a...

Effect of microstructural evolution and surface residual stresses on tribological behavior of friction stir welded AM60 magnesium alloy

Enhanced wear and fatigue properties of ER8 wheel steel with a gradient nanostructured surface layer induced by surface ultrasonic rolling
