Abstract

In this work the Lanthanum phosphate with 20% Yttria (LaPO4/Y2O3) composite prepared by Aqueous Sol-Gel process is machined by Abrasive Water Jet Machine (AWJM). The machiniability of this composite is studied by varying the input parameters namely Jet Pressure (JP), Stand-Off Distance (SOD) and Traverse Speed (TS) on Surface finish. Garnet of 80 mesh size is used as abrasive with a flow rate of 85 gms/min. The
micro structural characterization study reveals the presence of new element YPO4. This element enhances the machiniability and reduced porosity in the composite. Microscopy
examinations on machined surface reveals that partial overlapping at low JP, poor surface finish at high JP and SOD, Forged deficiency at maximum SOD and TS. The minimum
level of all input parameters are influenced to obtain acceptable Ra. Atomic Force Microscopy (AFM) on kerf surface shows micro wear track and peaks. The Multiple Regression Analysis (MRA) is developed for Ra to check the adequacy. From the 2
Analysis of Variance (ANOVA), SOD has the significant effect on Ra with a contribution of 53%. The influence of JP and TS on Ra is found to be 31% and 15%, respectively.
