Tribological properties and characterization of borided Co–Mg alloys

Open Chemistry, 2022
In this study, tribological properties and characterization of borided Co–Mg alloys were investigated. Cobalt–magnesium (CM) alloys with 97% Co–3% Mg composition were borided at temperatures of 850–900°C and for 1.5–4.5 h with solid boriding.

Evaluation of Wear Resistance of AISI L6 and 5140 Steels after Surface Hardening with Boron and Copper

Lubricants, 2023
(1) Background: Boriding is one of the most common methods of thermal-chemical treatment due to its excellent hardness and wear resistance of the produced diffusion layers. However, it has limited application compared to carburizing and nitriding because

Research on Method for Contactless Gas-Phase Boron Enrichment of Steels and Alloys Using Powder Boron Sources

Metals
Contactless gas-phase boriding is suitable for strengthening the surface of precision steel components because it avoids direct contact between the workpiece and the boriding medium, thereby helping to maintain dimensional accuracy and surface roughness.
