Abstract
In the current paper an extensive study on erosion wear is carried out on PTFE/HNT nanocomposites by air jet erosion tester as
per ASTM G76 standard. The test is conducted on nanocomposite samples those are made with 4%, 6%, and 8% by weight of
HNT in PTFE matrix. The experiments are designed in a user defined response surface methodology (RSM) and are performed
on the erosion tester. The control factors used are: composition (A) with 3 levels, pressure (B) with 3 levels and impingement
angle (C) with 4 levels. A full factorial design with 36 runs is planned. The results are then analyzed by using Design Expert
software in response surface methodology (RSM). Analysis of variance (ANOVA) is also carried out and a quadratic model with
regression equation is established. Surface plots are plotted corresponding to factors AB, BC, and AC. Conforming to the
minimization of erosive wear at desirability equal to 1: 4.67% by weight HNT composition, 0.9235 bar pressure, and 90
0
impingement angle, a wear rate of 0.0391x10
-5
g/g is found. Also plots representing the effect of impingement angle and pressure
on erosion wear rate are plotted. From the plots maximum wear is found corresponding to low impingement angles and higher
operating pressures
