Title:Fretting fatigue strength of titanium alloy RC 130B
Author(s):Liu, H.W.; Corten, H.T.; Sinclair, G.M.
Titanium Alloy
Abstract:An investigation was made to determine the influence of a number of variables on the fretting fatigue strength of RC 130 B Titanium alloy. The variables studied included different gripping materials, hardness of the gripping materials, gripping pressure, surface preparation of specimens, dry lubricants, metallic coatings and special screen gripping shims. An analysis of experimental results suggests that the primary mechanism responsible for fretting fatigue damage is the repeated frictional shear stress on the asperities or surface “high spots” which are in contact. The frictional force is influenced by cold welding or alloying tendency and by surface roughness. Based on prevention of fatigue crack initiation by this mechanism, a mathematical expression is proposed which relates the fretting fatigue strength to the fatigue limit of the specimen material, the hardness of the gripping material and the coefficient of friction.
