Résumé:
Titanium is used in the medical prostheses but its expensive cost limits its use A solution to this problem is to alloy it with copper In this optic we have elaboraled the binary Ti70Cu30 and have anodically treated it in three acidic soluitions XRD chronocoulometry and potentiodynamic polarization lechniques are used to study the corrosion behaviour of Ti70Cu30 alloy in three in three acidie colutions Different effects such as anodic treatment and copper addition titanium has been examinated this study revealed that Ti70Cu30 alloy resists better to corrosion in phosphoric acid before and after anodic treatment addition of 30 at % of copper has lead to a denser material with more noble corrosion potential and a cheap cost than pure titanium
