Effect of diamond-like carbon self-lubricant coatings on wear resistance of powder metallurgy products

Fenmo yejin jishu
The iron-based parts with different densities were prepared by powder metallurgy, and then were densified by ultrasonic shot peening. The diamond-like carbon (DLC) self-lubricating coatings were deposited on the sintered and shot peening samples with ...

Influence of Ultrasonic‐Assisted Milling on Surface Integrity and Fatigue Strength of a Low Alloy Steel

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 6, Page 2352-2362, June 2026.
ABSTRACT The milling process significantly influences the surface integrity of metallic components through machining induced near‐surface residual stresses. Modern hybrid machining processes, such as ultrasonic‐assisted milling (USAM), offer the potential to induce beneficial near‐surface compressive residual stresses compared to the near‐surface ...

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 ...
