Development of Tribological Test Equipment and Measurement of Galling Resistance of Various Grades of Stainless SteelSource: Journal of Tribology:;2016:;volume( 138 ):;issue: 002::page 24501DOI: 10.1115/1.4031398Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A mechanized galling tester has been developed to evaluate the galling resistance of material pairs at room temperature (RT) as well as at elevated temperature condition. The test rig has a facility for online measurement of frictional torque during the test which is useful in assessing the incipient scoring. Both the test rig and the test method conform to the recent ASTM G19608 standard. Galling resistance of two different grades of stainless steel SS 304 and 304 L has been evaluated in selfmated condition at RT and elevated temperature (300 آ°C). The parameter called galling50 has been reported for the materials tested. The galled surface indicated the severe plastic deformation in the direction of sliding and it is dominated by the typical adhesive wear mechanism. The recent ASTM G19608 test method for measurement of galling resistance of material pairs appears to be superior to an older ASTM G98 because galling behavior was prevailed by the stochastic wear phenomenon.
