Galling50 a Stochastic Measure of Galling Resistance J
May 26 2009 · A new parameter called the Galling 50 value is proposed to provide a statistically relevant measure of galling resistance. The Galling 50 value represents the stress value where galling is expected to occur in 50 of the specimens tested. Galling 50 is determined from the analysis of a series of tests that measure the probability of galling at different applied stresses. Mar 25 2008 · (1996).
