Aiming to improve the surface roughness of precision mould structural surface in finish machining, a new mould structural surface no-tool precision polishing method based on softness abrasive flow was brought forward. Dynamical model of softness abrasive flow in bound flow oriented to mould structural surface precision machining was established based on liquid-solid two-phase flow coupling theory...
The durability of carbon protective layers of thin film magnetic disks was examined with pin-on-disk tests, and the wear crosssection was estimated as the quantity of material worn away. However, measurement of the precise wear crosssection is difficult because the wear quantity in such tests is very small. Therefore, EPMA (electron probe microanalysis) with an EDS (energy-dispersive X-ray spectrometer)...
