| Outline of Final Research Achievements |
Under humidity controlled atmospheres of oxygen and/or argon, wear experiments have been done for seven kinds of metals: gold, silver, copper, platinum, nickel, titanium and iron. In case of iron, temperature and non-friction time were also changed. As the chemical activity of metals was increased, the wear of metals was influenced firstly, by oxygen and secondly, by water vapor. The effects of oxygen and water vapor, individually, as well as oxygen-water vapor combination were determined as follows: the wear of iron was explained by the combination of the hardening effect associated with oxide and the softening effect due to hydroxide.
