A program has been written to compute flash temperature distribution using the Kuhlmann-Wilsdorf formulas for the interfacial temperature under arbitrary sliding speeds. As such the program can account for the effect of reversing the roles of two dissimilar materials in a sliding contact. The program was applied to scuffing test data on steel disks. The predicted mean flash temperature varied inversely with scuffing load for both the ground and polished specimens used in the scuffing tests. A paper describing the computational methodology of the program and the application to scuffing test has been prepared. Flat tests specimen blanks of three materials, have been finished at NBS and will be tested along with the commercially finished specimens acquired for this program. 1 ref., 1 fig.
