Influence of Suspended Talc Particles in Oil And Nature of Material Microconstituents on Sliding Wear Characteristics of Cast Iron and Zinc-based Alloy

Abstract: This investigation pertains to some observations on the sliding wear behaviour of a zincbased alloy and grey cast iron as influenced by the content of talc particles suspend in SAE40 oil lubricant. Tribological parameters evaluated using a pin-on-disc machine were wear rate, frictional heating and friction coefficient. The study suggests that the presence of suspended talc particles in the oil lubricant brought about improved wear response of the samples. However, the degree of improvement was strongly depende… Show more

“…This ultimately results into the smearing of graphite particles followed by the formation of solid lubricant film on the sliding surfaces [22][23][24][25][26][27][28][29]. The presence of an external lubricant like oil brings about improved wettability to the lubricant film with the sliding surfaces making the film more effective and stable [15,[22][23][24][25][26][27][28][29][30]. Cracking tendency of the material also gets suppressed in the presence of an oil lubricant thereby providing the graphite phase a better opportunity to smear on the sliding surfaces and form lubricant film.…”

“…An appraisal of the above discussion suggests that addition of solid lubricants in externally added base lubricants like oil proves more beneficial in terms of the sliding wear response of materials [22][23][24][25][26][27][28][29][30] than when dispersed in the sliding material system [11][12][13][14][15][16][17][18][19][20][21]. Furthermore, no direct correlation exists amongst different controlling parameters like sliding speed, pressure, test environment and nature and characteristics of the sliding pair material system and the solid lubricants; and rather the parameters produce a synergistic effect on the wear behaviour.…”
