Improving the properties of titanium alloys by laser treatment at room temperature in the normal atmosphere without external media

Titanium alloys are the workhorse alloys in different applications. To overcome high cost of these alloys the efficiency and life time of the alloys must be increased. Laser irradiation of Ti6Al4VELI at room temperature and in the normal atmosphere without any external media improve surface hardness and wear. Laser treatment is suitable for both field works and industry. The improve …
