The impact of SiC, Al_2O_3, and B_2O_3 abrasive particles and temperature on wear characteristics of 18Ni (300) maraging steel in abrasive flow machining (AFM)

摘要

In this research, a one-way abrasive flow machining (AFM) was sketched and built, and the impact of temperature on surface roughness (R-a) values and material removal rate (MRR) before and after each test have been investigated considering the SiC. Al2O3, and B2O3 particles as abrasive particles. The abrasive particles were dispersed at 35 wt.% in the prepared media. The findings revealed that the media containing Al2O3 abrasive particles had higher surface roughness compared to the SiC and B2O3 particles. The maximum variation of surface roughness for SiC, Al2O3, and B2O3 particles was observed at - 196 degrees C, which was 2.991, 2.588, and 1.684, respectively. In addition, the material removal rate values decreased for all the prepared samples as the temperature was reduced. At lower temperatures, lower material removal rate values were recorded since the viscosity of the abrasive paste increased. (C) 2021 Hydrogen Energy Publications LLC. Published by Elsevier Ltd.
