FRICTION BEHAVIOR OF 304 STAINLESS STEEL OF VARYING HARDNESS LUBRICATED WITH BENZENE AND SOME BENZYL STRUCTURES

摘要

The lubricating properties of some benzyl and benzene structures were determined by using 304 stainless steel surfaces strained to various hardnesses. Friction coefficients and wear track widths were measured with a Bowden-Leben type friction apparatus by using a pin-on-disk specimen configuration. Results obtained indicate that benzyl monosulfide, dibenzyl disulfide, and benzyl alcohol resulted in the lowest friction coefficients for 304 stainless steel, while benzyl ether provided the least surface protection and gave the highest friction. Strain-hardening of the 304 stainless steel prior to sliding resulted in reduced friction in dry sliding. With benzyl monosulfide, dibenzyl disulfide, and benzyl alcohol changes in 304 stainless steel hardness had no effect upon friction behavior.
