Ti6Al4V alaşımı ve Saf Titanyumun  (Cp-Ti) açık atmosferde 600, 650 ve 700 °C
için,  1, 2, 4, 8, 16, 24, 48, 72 saat
sürelerinde oksidasyon kinetiği davranışları incelenmiştir. Oksidasyon işlemi
sonrası numune yüzeyleri X-ray difraksiyonu (XRD), taramalı elektron mikroskobu
(SEM) ve enerji dispersive spektroskopisi (EDS) yardımı ile
incelenmiştir. Ti6Al4V alaşımı ve saf
Ti oksidasyon işlemi sonrasında başarı ile kaplanmıştır. Oksidasyona uğratılan
numunelerin aktivasyon enerjileri hesaplanmıştır. Ti6Al4V için aktivasyon
enerjisi 201.3kJ/mol, Cp-Ti için ise 269.4kJ/mol hesaplanmıştır.

The oxidation kinetics behavior of Ti6Al4V alloy and pure Ti (Cp-Ti) were investigated under air atmosphere at temperatures of 600, 650 and 700 °C for 1, 2, 4, 8, 16, 24, 48, 72 h have been identified in the study. The oxidized samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM). After thermal oxidation, a thin oxide layer was formed on the surfaces and oxygen diffusion took place into the metal. The oxide layer formed rutile and anatase (TiO2) form. The thickness of the oxide layer increased with increasing the oxidation temperature and time The activation energies for oxidation were estimated for Ti6Al4V alloys and Cp-Ti, 201.3kJ/mol for Ti6Al4V and 269.4kJ/mol for Cp-Ti were found, respectively.
