In this work, a new technique for Laser irradiation of Ti6Al4VELI was developed, this alloy is an alpha-beta structure, the irradiation was done at room temperature in the normal atmosphere without any external media, the effects of laser irradiation on the Ti6Al4VELI such as the chemical composition of the alloy before and after laser irradiation were recorded by Energy dispersive X-ray “EDX” technique. the affected zone (thickness) of the laser irradiation technique was limited to the surface in micro to the nanoscale. The variation in mechanical properties due to laser irradiation at different wavelengths was measured by the determination of the variation of modulus and hardness at maximum load with a number of pulses. The wear rate was measured for the Ti6Al4VELI before and after laser irradiation at 5000 pulses where the maximum improvement in the hardness occurs at all wavelengths, in the current study, it improves surface mechanical characteristics. The effect of laser irradiation on the structures was studied by SEM, the quantitative analysis was done at all irradiation conditions. Laser treatment is suitable for both field works and industry. The improvement in mechanical properties occurs due to microstructure changes without significant changes in chemical composition. the efficiency and lifetime of the alloys were increased, the work is registered as patent number 24014 in the Egyptian patent office.
