“…7 Several methods for surface modification of cemented carbides are currently in use, including surface coating technology, laser treatment, electron beam irradiation, or ion implantation. [8][9][10][11][12] Among these, surface coating technology is a prominent area of research. Coatings with high hardness, exceptional wear resistance, and heat resistance can significantly improve the hardness and strength of cemented carbides.…”

This study focuses on preparing two types of cemented carbides: one with Ti elements and the other without, using a stepwise sintering process, primarily evaluating their mechanical properties. The research includes a thorough analysis of microstructure changes and post-wear surface alterations, coupled with assessments of phase composition, element content, relative density, surface hardness, fracture toughness, and wear properties. Results reveal that cemented carbides treated with in-situ surface modification under high-temperature nitrogen atmospheres exhibit exceptional densification. An in-situ hard-phases layer, predominantly TiN or Ti(C, N), is gradually grown on the surface of the WC-Co-Mo-TiNC cemented carbides, enhancing surface hardness and fracture toughness. This technology fortifies the material against indentation, crack expansion, and fracture, significantly improving wear resistance and extending service life. In essence, the in-situ surface modification technology, especially under high-temperature nitrogen atmospheres, emerges as a transformative approach, enhancing mechanical properties and substantially improving wear resistance for prolonged practical applications.

“…As the extremely high energy density (10 8 -10 9 W/cm 2 ) shifts to the surface of materials in a very thin layer (no more than tens of micrometers) within a few microseconds, causing extremely rapid melting or even evaporation and resulting in surface tissue imbalance and accompanied by changes in physicochemical properties [9,10]. Meanwhile, self-quenching (10 8 -10 9 Ks −1 ) and thermal stress impact processes occur quite intensively in the near-surface layers [11][12][13][14]. Meanwhile, self-quenching (10 8 -10 9 Ks −1 ) and thermal stress impact processes occur quite intensively in the near surface layers.…”

High current pulsed electron beam (HCPEB) has recently been developed as an effective technique of material surface modification. In this research, a self-developed HCPEB equipment (HOPE-I) was adopted to perform surface modification on quenched and tempered 40CrNiMo7 steel. A composite nanometer structure was formed on the modified surface layer, and the martensite transformation and the dissolution and fracture of cementite can be observed. After initial irradiation, the high cooling rate caused the formation of nanocrystalline on the surface. With continuous irradiation treatments, the cooling rate gradually reduced, while the carbon kept dissolving and ended with surface composition homogenization. Both competitive factors result in the evolution rule of nanometer dimensions of surface structure. After HCPEB treatment, the average size of austenite phase on the modified surface decreased from micron-sized to nanoscale. The corrosion rate decreased from 0.12 mm/a to 0.02 mm/a, showing remarkable improvement of corrosion resistance. The main factors of the improvements of corrosion resistance property are the flat, dense structured and preferred crystal orientation on the modification layer of the treated material surface.
