“…However, the safest hard-on-hard bearings, from the mechanical perspective is PCD-on-PCD because the maximum von Mises stress value is only 2.47% of the PCD’s yield strength. Although the von Mises stress value of PCD-on-PCD is the highest compared to the metals and ceramic hard-on-hard bearings used in the current study, the Yield strength of PCD is very high at 5849.7 MPa [ 44 ] making the percentage of the maximum von Mises stress to the yield strength very small. In terms of the safest bearings after PCD-on-PCD, CoCrMo-on-CoCrMo and Al 2 O 3 -on-Al 2 O 3 had the percentage of maximum von Mises stress to respective yield strength, at 10.79% for CoCrMo-on-CoCrMo and 13.49% for Al 2 O 3 -on-Al 2 O 3 .…”

Due to polymeric wear debris causing osteolysis from polymer, metal ions causing metallosis from metal, and brittle characteristic causing fracture failure from ceramic in the application on bearing of total hip prosthesis requires the availability of new material options as a solution to these problems. Polycrystalline diamond (PCD) has the potential to become the selected material for hard-on-hard bearing in view of its advantages in terms of mechanical properties and biocompatibility. The present study contributes to confirming the potential of PCD to replace metals and ceramics for hard-on-hard bearing through von Mises stress investigations. A computational simulation using a 2D axisymmetric finite element model of hard-on-hard bearing under gait loading has been performed. The percentage of maximum von Mises stress to respective yield strength from PCD-on-PCD is the lowest at 2.47%, with CoCrMo (cobalt chromium molybdenum)-on-CoCrMo at 10.79%, and Al2O3 (aluminium oxide)-on-Al2O3 at 13.49%. This confirms that the use of PCD as a hard-on-hard bearing material is the safest option compared to the investigated metal and ceramic hard-on-hard bearings from the mechanical perspective.

“…However, with the increase of grinding depth, the passivation of the grinding wheel caused by diamond wear also increased as well. To characterize and measure the wear of the diamond grain, Abdul-Rani et al 18 studied the relationship between the wear rate and the diamond grain size by using ABAQUS software, and established the wear rate equation of diamond tools cutting granite by applying the Von Mises stress acting on the material. Xiang et al 19 coupled the Usui abrasive wear model with the Arrhenius extended graphitization wear model, and combined a user-defined subroutine into a thermodynamic FEM model to achieve tool wear estimation for diamond drilling of SiCp/Al6063 composites.…”

With the exploitation of marine resources, the development of maintenance operation technology for subsea pipelines transporting oil and gas has become the focus worldwide. Diamond bead wire serves as important engineering equipment in subsea pipeline maintenance, and the study of the wear mechanism of diamond grains on the beads is key to improving the cutting efficiency and lifetime of diamond bead wire. In this work, a theoretical model of the mechanical wear rate of the diamond grain was established, and a simulation model of the diamond grain cutting X65 pipeline steel was developed by applying smoothed particle hydrodynamics method. By studying the effects of the cutting factors of the diamond grain on mechanical wear, the mechanisms of adhesive wear, abrasive wear, and fatigue wear were clarified. The results indicate that the diamond grain in line contact or large surface contact with X65 steel contributes more to wear rate reduction than point contact; The mechanical wear rate predominated by adhesive wear and abrasive wear of the diamond grain increases with the increase of cutting speed and depth. And when the cutting speed is 22–26 m/s and the depth is 20–30 μm, the growing trend of the mechanical wear rate turns gentle, which is more suitable to balance improving cutting efficiency and reducing mechanical wear.
