The size and distribution of wear particle in lubricating oil, as important numerical information available ferrography, is one the key indexes diagnosis. In this paper, a new method for measuring abrasive particles proposed. First, all fluid left standing until are precipitated to bottom. Then, container inverted whole precipitation process recorded by magnetic induction instrument. And accord...
The cubic Fe3O4 nanoparticles with sharp horns that display the size distribution between 100 and 200 nm are utilized to substitute the magnetic sensitive medium (carbonyl iron powders, CIPs) and abrasives (CeO2/diamond) simultaneously which are widely employed in conventional magnetorheological finishing fluid. The removal rate of this novel fluid is extremely low compared with the value of co...
Weyl fermions are massless chiral particles first predicted in 1929 and once thought to describe neutrinos. Although never observed as elementary particles, quasiparticles with Weyl dispersion have recently been experimentally discovered in solid-state systems causing a furore in the research community. Systems with Weyl excitations can display a plethora of fascinating phenomena and offer grea...
The present study examined wear characteristics of A356/melon shell ash particulate composites. Dry-sliding the stainless steel ball against specimen disc revealed the abrasive wear behavior of the composites under loads of 2 and 5N. The composite showed lower wear rate of 2.182 × 10-4 mm3/Nm at 20 wt% reinforced material under load of 5N. Results showed that wear rate decreased significantly w...
