Abstract

<p>The experiments such as corrosion mass loss and polarization curve test have been carried out to obtain corrosion behavior of Ti in a mixture of 10 mass% hydrogen peroxide and 10 mass% ammonia solutions. The polarization resistance curve by differentiating the experimental polarization curve told us that the corrosion system has shown the fast reaction properties and its corrosion rate was largely influenced by existence of oxide film on the titanium. It was found that an estimation of corrosion rate using the characteristics on the polarization resistance curve is in good agreement with that of the corrosion mass loss measurement.</p>
