Digitized edition from print [produced by Natural Resources Canada]. Includes bibliographical references (p. 6-7). “Cathodic polarization measurements carried out on ASTM 6061-T6 aluminum alloy in three Ontario mine waters of different acidities and compositions provided a rapid estimate of relative corrosion rates even though these rates were too low to be readily measured by conventional weight-loss methods. The results showed that corrosion rates in water from the Helen iron ore mine, were much lower than those in waters from the two other mines. This correlated with the corrosion fatigue behaviour of ASTM 6061-T6 alloy in the same waters"--Abstract, p. i. Includes abstract in French. gccst Metals Canada. Natural Resources Canada. Canada.
