Tribological Behaviour Of Quenched And Tempered, And Austempered Ductile Iron At The Same Hardness Level
A.S. Md Abdul Haseeb
The tribological behaviour of ductile iron heat-treated by two different procedures viz. quenching and tempering, and austempering to an identical matrix hardness of 445 KHN is compared. Wear tests were carried out using a pin-on-disc type apparatus under dry sliding conditions at a linear speed of 1.18 m s -1. Applied load and sliding distance in the range of 7.5-30 N and 2x10 4-6x10 4 m, respectively, were used. It was observed that under all test conditions, austempered ductile iron exhibits a better wear resistance than quenched and tempered ductile iron, although both have an identical chemical composition and matrix …
Effect Of Mechanical Factors On Tribological Properties Of Palm Oil Methyl Ester Blended Lubricant
Effect Of Mechanical Factors On Tribological Properties Of Palm Oil Methyl Ester Blended Lubricant
A.S. Md Abdul Haseeb
The effects of mechanical factors viz. applied load and temperature on the tribological performance of 5% palm oil methyl ester (POME) blended lubricant were studied using a steel-cast iron pair. Wear and frictional measurements were made using a stationary steel ball and a reciprocating cast iron plate in a modified universal wear and friction testing machine. The test conditions were contact pressure, 400 MPa; mean contact velocity, 0.34 m/s; reciprocating stroke, 80 mm; loads, 100-1100 N (fixed temperature); and temperature, 40-140°C (fixed load). Wear scar surfaces were investigated using scanning electron microscopy (SEM) to understand the wear mechanisms involved. Analysis …
