Erosive Corrosive Wear Performance of Single Layer CrN Coatings on AISI 304 Stainless Steel in Sea Water Centrifugal Pumps using Steady State Analysis
The purpose of present study was to investigate the erosive corrosive wear behavior of single layer (CrN) coatings on AISI 304 Stainless Steel samples with varying coating thickness (0-200 nm) in the range of 50 nm. The slurry jet erosive test was conducted on Slurry Jet Erosion Tester in saline slurry (3.5wt% salt) under the different working conditions with varying impact velocity (10-25 m/s), impingement angle (30°-75°) and erodent discharge (160-280 gm/min). Steady state analysis was applied to find optimum parameters for the minimization of erosion rate of various coated and uncoated samples. The finding of steady state condition tests indicated that the erosion rate increased with the increase in impact velocity and erodent discharge but decreased with the increase in coating thickness. The results also indicated that erodent discharge was the most significant factor, followed by impingement angle and impact velocity for the CrN coated samples. The SEM characterization of the eroded samples was carried out in order to analyze the topography of the eroded surface to investigate the wear mechanisms induced by slurry jet erosion test
Swapping path-spin intraparticle entanglement onto spin-spin interparticle entanglement
Based on a scheme that produces an entanglement between the spin and the path
variables of a single spin-1/2 particle (qubit) using a beam-splitter and a
spin-flipper, we formulate a procedure for transferring this intraparticle
hybrid entanglement to an interparticle entanglement between the spin variables
of two other spatially separated spin-1/2 particles which never interact with
each other during the entire process. This procedure of entanglement swapping
is accomplished by a Mach-Zehnder setup in conjunction with the Stern-Gerlach
measuring device, using suitable unitary operations. The proposed protocol,
thus, enables the use of intraparticle entanglement as a resource - a feature
that has remained unexplored.Comment: 5 pages, 1 Figur
