Friction and Wear Characteristics of Micro‐Arc Oxidation Coating on Ti6Al4V Alloy—A Review

Biosurface and Biotribology, Volume 11, Issue 1, January/December 2025.
ABSTRACT Ti6Al4V alloy is widely used in artificial joints, artificial bones, and dental implants due to its elastic modulus similar to that of bone, good biocompatibility and non‐cytotoxicity, low density, and excellent fatigue resistance. However, its utility is constrained by the low surface hardness and inadequate wear resistance.

Bending fatigue behavior of metastable and stable austenitic stainless steels with different surface morphologies

Fatigue &Fracture of Engineering Materials &Structures, Volume 47, Issue 12, Page 4755-4770, December 2024.
Abstract The surface morphology has a significant influence on the fatigue behavior of components. For austenitic stainless steels (ASSs), this issue is even more pronounced due to their metastability. Based on the complex deformation mechanisms of metastable ASSs, which include dislocation slip, deformation twinning, and deformation‐induced ...

Fatigue Limit Estimation for Post‐Peened Induction‐Hardened and Tempered Steel Considering Changes in Surface Properties

Fatigue &Fracture of Engineering Materials &Structures, Volume 47, Issue 12, Page 4607-4617, December 2024.
ABSTRACT Shot peening (SP) and fine particle peening (FPP) were performed as post‐treatments on induction‐hardened and tempered AISI 4140 steels. Furthermore, the combined effects of surface characteristics including changes in surface morphology, compressive residual stress, and hardness on the fatigue limit were quantitatively examined.

Effect of Surface Mechanical Attrition Treatment on Surface Topography and Dry Sliding Wear Performance of AA7075‐T6

Advanced Engineering Materials, Volume 26, Issue 21, November 2024.
Surface roughness affects material life, especially fatigue and wear. This study examines surface mechanical attrition treatment (SMAT) on AA7075‐T6 aluminum alloy, using low‐speed vibration, varied shot amounts, and sizes. SMAT produces smoother surfaces, lowers friction, and improves wear performance, enhancing tribological properties and engineering
