Abstract EN
Nanodiamonds, which are the main components of slurry in the precision lapping process of magnetic heads, play an important role in surface quality.
This paper studies the mechanistic features of nanodiamond embedment into a Sn plate in the lapping process.
This is the first study to develop mathematical models for nanodiamond embedment.
Such models can predict the optimum parameters for particle embedment.
From the modeling calculations, the embedded pressure satisfies p0=3/2·W/πa2 and the indentation depth satisfies δ=k1P/HV.
Calculation results reveal that the largest embedded pressure is 731.48 GPa and the critical indentation depth δ is 7 nm.
Atomic force microscopy (AFM), scanning electron microscopy (SEM), and Auger electron spectroscopy (AES) were used to carry out surface quality detection and analysis of the disk head.
Both the formation of black spots on the surface and the removal rate have an important correlation with the size of nanodiamonds.
The results demonstrate that an improved removal rate (21 nm·min−1) can be obtained with 100 nm diamonds embedded in the plate.
