Abstract
The aim of his work is to elucidate the characteristics of wear of AISI 304 and Cm. 3 steels at the friction on the coke. tests were carried out on abrasive wear by rotaton of steel samples on the powdre cocke with a variable pressing force on the samples. Abrasive wear hardening under compression, microhardness near the friction surface, the fracture at friction surface were investigated. It has been shown that the characteristics of strain hardening of the material deremine the wear resistance at abrasive wear.
Differences in the nature of strain hardening of AISI 304 and Cm. 3 steels lead to the fact that at low pressures, wear resistance of Cm. 3 is greather them of AISI 304 stainless steel. At pressures higher then 30 kPa, wear resistance of AISI 304 steel becomes greater them of Cm. 3.
Keywords: wear resistance, fracture, deformation

Our Carbon-Ukraine team (Y-Carbon LLC) are thrilled to start a new RIC2D project MX-Innovation in collaboration with Drexel University Yury Gogotsi and Khalifa University! Amazing lab tours to project collaborators from Khalifa University, great discussions, strong networking, and a wonderful platform for future collaboration.
MXenes potential applications include sensors, wound healing materials, and drug delivery systems. A recent study explored how different synthesis methods affect the safety and performance of MXenes. By comparing etching conditions and intercalation strategies, researchers discovered that fine-tuning the surface chemistry of MXenes plays a crucial role in improving biocompatibility. These results provide practical guidelines for developing safer MXenes and bring the field one step closer to real biomedical applications.
An excellent review highlighting how MXene-based sensors can help tackle one of today’s pressing environmental challenges — heavy metal contamination. Excited to see such impactful work moving the field of environmental monitoring and sensor technology forward!
