Modélisation de l’usure érosive des pièces en alliage d’aluminium

Abstract

Our scientific research dealt with the study of erosive wear, happening for Aluminium alloy as a result of its collusion to projectiles. This was under the influence of constant factors that are: time, speed and distance. On the Other hand, there were some variable factors that could be illustrated in the diameters sand grains and the angle of libel and the hardness of the alloy. And has been studied the impact of variable factors affecting the phenomenon of erosion wear. Moreover and according to the statistical methods for planning experiments were selected as appropriate for the pilot scheme in order to obtain a mathematical model of these variable factors, this model has enabled us to obtain the graphs that show the relationship between variables and the resulting erosion. This will lead us to analyze these graphs and logical scientific analysis to come out with some clear scientific conclusions that could probably suggest appropriate scientific solutions to reduce the severity of this negative phenomenon and the resulting economic losses and considerable material in our daily lives.
