Özet

This study aims to examine the wear performance and electrochemical corrosion properties of Ti15Mo alloy produced by mechanical alloying (MA) in simulated body fluid (SBF) environment. Ti15Mo alloy was produced by milling in a mechanical alloying device for 120 min. The alloys produced are examined using SEM, X-ray diffraction, hardness and density measurements. Three different loads, four different sliding distances and 1 m center dot sec(-1) sliding speed were used in the tests performed in SBF environment. Corrosion tests were carried out using potentiodynamic polarization technique, cyclic polarization measurement at 37 degrees C body temperature, in SBF, with a scan interval of +/- 750 mV and scan rate of 1 mV/sec. Density and hardness measurement results of MA'ed Ti15Mo alloy are 4.93 g/cm(3) and 299.5 HV, respectively. As a result of increasing the load applied during the wear tests, the resistance of the samples against wear has decreased and the amount of wear has increased. Corrosion tests showed that the potentiodynamic polarization parameters were 36.969 mA/cm(2) for I-corr value and 0.54448 mmpy for corrosion rate. Corrosion tests made in the environment of SBF and at body temperature revealed that there was very little pitting corrosion observed in MA'ed Ti15Mo alloy.
