Erosive wear tests were done under small range of velocity and impingent angle at constant rate of [Al.sub.2][O.sub.3] particle as erodent. All the tests are done under relative humidity RH=60-65%, and ambient temperature condition of 32-33[degrees]C and also one test is carried out at high temp i.e.
This may be due to the direct striking of the erodent particles on the specimens .Graphs shows that as angle increases the mass loss decreases .the erosive wear at 60 degree and at 75m/s velocity it is .008g and at 30 degree it is .0 37 g.
It shows that as angle is constant and velocity increases from 45 m/s to 75m/s the mass loss of the material increases, there is rapid increase in the mass loss with velocity at 30[degrees] angle of impingent .This may be due to the direct striking of the erodent particles on the specimens .Graphs shows that as angle increases the mass loss decreases .the erosive wear at 60 degree and at 75m/s velocity it is .009g and at 30 degree it is .0 041 g.
Montmorency vit alors ce que nous appelons un [much less than] exil interrieur [much greater than] Des la fin du deuxieme conflit mondial, les changements economiques et culturels qui surviennent au Quebec rejoignent Montmorency et
erodent silencieusement les fondements de son agregation communautaire.
