Tribological
properties of structural alloys for the heat exchange equipment parts subjected
to fretting
Trobological characteristics of sliding friction in stainless steel and titanium alloys in dry and water lubricated conditions
have been determined. The character of the coefficient of friction variation with load and the duration of tests have
confi rmed the prevailing wear mechanism in these materials to be frictional fatigue fracture that in the case of titanium
alloys is accompanied with adhesive interaction and plastic plowing. The frictional fatigue curves built in a result of this
investigation make possible to estimate the materials tribological longevity.
