Investigation of Residual Stress, and corrosion behavior of AA6082/Al 2 O 3 /C/ Si 3 N 4 Composite Material

By Dhananjay Kumar, Yashpal, Ratnesh Kumar Sharma

Abstract: The main objective of the current study was to create AA6082/ Al2O3/C/Si3N4 Composite Material by the use of stir casting. The properties of the AA6082/ Al2O3/C/ Si3N4 Composite Material shown a significant improvement, with a micro-hardness rise of 13.5% and a residual stress decrease of 60%. As the testing parameters were increased, the residual stress of the AA6082/ Al2O3/C/ Si3N4 Composite Material rapidly decreased from -65MPa to -15MPa. An electromagnetic …

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 …

Computational investigation of the influence of process parameters of 3D printed PLA material

By Saurabh Pachauri, Naveen Kr. Gupta, Ankit Gupta

Abstract: This study uses numerical simulation to examine the relationship between critical process parameters say, feed rate, layer height, and raster angle, on residual stresses and distortions and on the achievable density of FFF prints to identify the optimal input parameter combinations for ISO 527-2 type 1A. Methods of additive manufacturing that are utilised widely used to manufacture thermoplastic parts is fused filament fabrication. High residual stresses are one of the …
