Abstract: Silicon nitride bearing balls of 12.7 mm diameter were used to evaluate the wear and friction reducing characteristics of admixtures of paraffin oil with 0.5% w/v solution of 1,5-di-p-methoxyphenyl- 2,4-dithiomalonamide and 3,5-di-p-chIorophenrlimino-1,2,4-dithiazolidine in a four ball test. Both the additives were found to be quite active in reducing wear-scar diameter and friction coefficient values and exhibited higher values of flash temperature parameter and load wear index. A comparative EP activity evaluation of both the additives using silicon nitride and alloy steel balls was undertaken to assess better applicability of silicon nitride balls in a four ball test.
