| Abstract | Lapping process is one of the most important processes in modern hard disk drivemanufacturing. Using lubricant in the lapping process does not only reduce thefriction but also transfers heat and captures debris away from the surface contacts.The effects of tribological parameters on the lubricant characteristics and frictionregime were investigated, using tribometer. The tribological behaviors of thelubricated alumine-titanium carbide (AlTiC) surface with different types oflubricants were also investigated. The coefficient of friction values of stainless steelball sliding on the lubricated surface exhibited much lower than dry surface. Thevariation of normal force and sliding speed did not affect lubricant regime on drysurface. For the lubricated AlTiC surface with both ethylene glycol-based and oilbased lubricants, the friction regime changed as a function of both normal force andsliding speed. Scanning electron microscopy confirmed deeper and wider wear trackson dry lubricant than those with lubricants. |
