Beyond the Surface: Unveiling the Secrets of Drill Tool Repair
Dr. B. Cheniti · 11/11/2025
Where does a repaired tool truly regain its strength — in the weld, the interface, or the unseen chemistry of its particles?
This project ventures into the complex world of tungsten carbide (WC) and its metallic matrix, exploring how decarburization, microstructural evolution, and interfacial transformations shape the integrity of repaired drilling tools.
Through the lens of advanced TIG repair techniques, the study investigates how extreme conditions corrosion, abrasion, and tribo-chemical wear, influence the very foundations of tool performance.
