Cr2O3‐Mediated Phase Transformation and Microstructural Evolution in LDED CuAlMnTi SMA Coatings Toward Resource‐Efficient Wear Protection

EcoMat, Volume 8, Issue 11, November 2026.
The Cr2O3‐reinforced CuAlMnTi shape memory alloy coatings were fabricated via laser direct energy deposition. The addition of Cr2O3 refined the microstructure, altered the phase transformation behavior, and improved the high‐temperature tribological performance.

Synergistic B/Si Microalloying Induced Wear Resistance Improvement in FeCoNiCrCu High‐Entropy Alloy Coatings Prepared by Annular Oscillating Laser Deposition

Rare Metals, Volume 45, Issue 11, November 2026.
ABSTRACT To address the insufficient wear resistance of high‐entropy alloy (HEA) coatings under extreme conditions, FeCoNiCrCu and FeCoNiCrCuB0.03Si0.03 microalloyed coatings were fabricated via annular oscillating laser deposition. This work systematically investigated the effects of synergistic B/Si addition on their phase composition, microstructure,

Erosion Potential of Commercial Fluoride‐Free Mouthwashes on Dental Hard Tissues

International Journal of Dental Hygiene, Volume 24, Issue 4, Page 658-667, November 2026.
ABSTRACT Purpose Mouthwashes often present acidic pH, which raises concerns about their potential contribution to erosive tooth wear. This study evaluated the erosive potential of commercial fluoride‐free mouthwashes using a screening method.
