Effects of Multiple Quenching Treatments on Microstructure and Hardness of O2, D2, and D3 Tool Steels

Journal of Manufacturing and Materials Processing
The effects of multiple austenitizing and quenching (AQ) thermal cycles on the microstructure and hardness of AISI O2 (90MnCrV8), D2 (X153CrMoV12), and D3 (X210Cr13) tool steels were systematically investigated.

Toward the Application of Multiaxial Failure Criteria: Mean Stress Sensitivity of Carbide‐Rich, High‐Alloy PM‐HIP Tool Steels Under Axial and Torsional Cyclic Loading

steel research international, EarlyView.
This study quantifies axial and torsional long‐life fatigue (LLF) behavior of three carbide‐rich PM‐HIP tool steels, correlating LLF strength with intrinsic defect size and cleanliness, thereby extracting material‐specific mean stress sensitivities and Haigh diagrams.

The Influence of the Pretreatment of Tool Steel on the Running‐In Phase of Diamond‐Like Carbon Coatings

steel research international, EarlyView.
The influence of tool steel pretreatment on the running‐in behavior of TiNb‐diamond‐like carbon (DLC) coatings is investigated. Ion etching promotes carbide protrusion and increases coating roughness, while post‐deposition polishing reduces surface asperities.

Cobalt‐Doped Diamond‐Like Carbon Coatings Combined With Functionalised Polymers for Enhanced Tribological Performance

Lubrication Science, Volume 38, Issue 4, Page 191-197, June 2026.
ABSTRACT In recent years, doped diamond‐like carbon (DLC) coatings combined with functionalised copolymers have gained attention as a lubrication concept. While silicon‐doped DLC has been widely studied, polymer‐assisted lubrication on other doped DLC systems remains less explored.
