  Parametric optimization of residual stress of TiO2 composite coating

  By Bhuwan Khare, Yashpal, Ratnesh Kumar Sharma

  Abstract: The primary objective was to develop a composite coating by utilizing the HVOF thermal spray technique and including TiO2. The substrate was covered with a high-quality composite layer utilizing the HVOF coating process. The TiO2-based powder and carbon powder were initially combined in the mixer for deposition. The composite powders were applied via an HVOF torch, namely the PT F4 model. The firearm frequently produces a high-speed flow of extremely …

  Parametric optimization of COF of fabricated AA6082/Si3N4/C/Al2O3 composite

  By Dhananjay Kumar, Yashpal, Ratnesh Kumar Sharma

  Abstract: In the present experimental investigation AA6082/Si3N4/C/Al2O3 composite was successfully fabri-cated using stir casting technique combined with electromagnetic stirrer for wear resistance applica-tions. The produced AA6082/Si3N4/C/Al2O3 composite exhibits improved tribological and me-chanical and properties, according to the experimental results. The generated composite has a micro-hardness range of 60 to 110 HV and an average UTS of 150 to 200 MPa. The tribological perfor-mance was evaluated using a pin on disc tribometer. …
