| Abstract | ||||
| The object of this research is to investigate the effect of water sand jets on the erosion of metals. A test apparatus was designed and constructed to carry out this investigation. It was capable to eject water jets, carrying sand particles in its stream, on metal specimens. The jets were directed at angles of impact varying between 15 and 90 degrees. Computer programs were used to correlate the experimental data in a suitable form with reasonable accuracy using dimensional and regression analysis; then the variance analysis was used to check and compare these relationships. The obtained relationships can be used to estimate the erosion losses in specimens surfaces as well as to determine the effect of each test variable on the amount of erosion which may take place. It was found that maximum erosion losses occurred at an impingement angle of 33° i.e. exhibit ductile erosion responses. This is approximately 2.5 times its value at 90° and about 1.3 its value at 15°. The obtained results were found to be in good agreement with the corresponding results obtained by previous investigators. | ||||
