Abstract:
The objective of the study was the examination of erosion wear rate of Nitronic steel welds using
a slurry jet at high speed where impingement angle and time of particles attacking were
controlled. Here the experiments were conducted on the apparatus which impinge high velocity
jet of slurry of silica sand particles. The angle in this study was varied from 30 degree to 90
degree and time was varied from 30 min to 90 min. The examined samples include base metal
(21-4-N steel and 23-8-N)) as well as two types of gas metal arc welded samples by ER2209
filler metal with argon as shielding gas. The erosive wear study was conducted by silica sand
particles of size varying from 100 μm to 500 μm. The results of the study were plotted as the
calculated mass loss of eroded samples versus the angle of impingement and time of erosion.
