dc.description.abstract We tried to approach this work with as near as possible the influence of the most imposing of wear such as speed, applied load and nature of building materials mechanical parts called "antagonistic" or contact in the different mechanisms under the effect of environmental factors such as hydrogen and sea water. First, it has been necessary to provide a device for maintaining the "pin (wiper)" with the ability to receive different loads while enjoying the change in speed of the slide of the shaper used as an test rig (tribometer) Adding to these two parameters of influence, which is the hardness of materials engineering considered (XC48 and A60) determined separately using a parallel-jaw vise materializing and the third parameter. It was noted that these experiments were performed identically in two different natural contexts (for samples loaded with hydrogen and for samples immersed in natural seawater) characterizing the fourth parameter. Establish a series of experimental tests to identify the mass weighed before and after each test period (01Hour) on an electronic balance and deduct the "mass loss" caused, due to wear caused by friction of the peg on the contact surface of the sample. Finally, using the method of "experimental design", it was established a mathematical model governing the phenomenon (mass loss based on 04 factors of influence mentioned above and through a software "SURFER 32", we had the opportunity to plot each configurations presented in Chapters VIIII.A et VIIII.B . en_US
