Effect of Nanotextured Stainless Steel Surface Features on Antibacterial Properties and Osteoblast Activity In Vitro

Journal of Biomedical Materials Research Part A, Volume 114, Issue 4, April 2026.
Schematic illustration of the effect of nanotextured stainless steel feature size on antimicrobial performance and osteoblast activity. ABSTRACT Bacterial colonization and poor osteointegration are significant challenges for stainless steel implants. These issues often lead to implant‐associated infections, localized tissue damage, and implant failure,

A Review on Cracking in Laser Additive Manufacturing of Nickel‐Based Superalloys: Types, Formation Mechanisms, and Suppression Strategies

Rare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT Nickel‐based superalloys (Ni‐based superalloys) have attracted extensive attention in laser additive manufacturing (LAM) due to their capability to directly fabricate complex and high‐performance structural components. However, the rapid melting and solidification inherent to LAM result in intense thermal cycling, which induces high residual ...

The Microstructure and High‐temperature Cycle Oxidation Mechanism of the Nickel‐Based Superalloy Surface Treated by Laser Shock Processing and Ion Implantation at 1100 °C

Advanced Materials Interfaces, Volume 13, Issue 3, 3 February 2026.
Laser shock processingcombination with Hf ion implantation results in dual modification on the surface of GH202 nickel‐based superalloy, which induces a large number of crystal defects, providing channels for the diffusion of metal cations. Hf ion implantation forms an amorphous HfO2 layer.

Glass bead shot peening retards stress corrosion failure of titanium tanks [PDF]

, 1967
Rigidly controlled shot peening retards the incompatibility between titanium alloys and nitrogen tetroxide in rocket-propellant storage tanks. This sets up a residual compressive stress in the surface of a material which reduces tensile stresses in the ...
