The adhesion theory of friction is investigated using the model junction proposed by A. P. Green in 1954. The results of the model junction experiments are extended to study the wear mechanism. An attempt has been made to correlate the model junction results with similar results obtained by various experimentors using actual surfaces.
The friction results established that friction is independent of load which is in agreement with experiments done using actual surfaces. The model junction shows general agreement with the theoretical estimate of the friction and normal forces made by A. P. Green.
The wear results indicate general correlations between the model and actual surfaces with regard to particle shape and wear-load relationships.
In general, the results of the investigation indicate that actual surfaces should have small surface finish angles for minimum wear and that the double shear mode of junction failure provides an explanation for wear particle formation and the large values of the coefficient of friction found for outgassed metals sliding in vacuo. / Applied Science, Faculty of / Mechanical Engineering, Department of / Graduate
