VaporisateursIndex. décimale : 667.9 Revêtements et enduits Résumé : A novel pneumatic monodisperse spray was fabricated to validate the results of a probabilistic model and a stochastic model that were developed to predict surface area coverage of the monodisperse spray. Multiple droplets of a highly viscous 87 wt% aqueous glycerin solution were deposited on a flat, transparent, plexiglass substrate. The uniformly sized droplets (2.5 mm in diameter) impacted, spread, and coalesced on the substrate which led to the creation of a liquid sheet. Using a high-speed camera placed underneath the transparent substrate, droplet impact and resultant area coverage were recorded. When impinging droplets overlapped those already on the surface, surface tension forces pulled impacting droplets towards them, agglomerating the liquid, in a phenomenon known as drawback. The area covered by the liquid was measured from photographs using image analysis software. In the numerical models, droplets were set to impinge at random locations and drawback effects between droplets were accounted for by using a semi empirical correlation. While both models showed good agreement with the experimental results at lower area fractions, the stochastic model gave better estimates at larger area fraction due to its incorporation of drawback effects.

Dépôt par pulvérisationIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : It may be of interest to you to know that the first mechanically operated spray finishing machine used for finishing leather was invented 46 years ago, in the year 1927. This new machine was designed and developed by A. C. Lawrence Leather Co., in Peabody, Mass. It was described in the patent, which was later issued in July, 1934, as "An Apparatus for Applying Coating Material to Leather or Hides for the Manufacture of Patent Leather." It was the intent of the inventor to use this device to improve the method of applying the varnish finish coats on patent leather. At the time this material was being applied by hand brushing or swabbing, a method which was slow and expensive.
The original machine was semiautomatic in operation and was arranged so that the spray gun carriage could travel continuously up and down in a vertical transverse motion. The leather to he sprayed was supported by rope toggles in a wooden frame which was suspended from an overhead monorail conveyor track. The frame was advanced horizontally by a motorized conveyor chain with an intermittent indexing movement and it remained stationary for each stroke of the spray gun carriage.En ligne : https://drive.google.com/file/d/1ByRzmF-hDafSnj5PyT5Gx7IX2C3s39G_/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=38784

Titane -- AlliagesIndex. décimale : 667.9 Revêtements et enduits Résumé : A thermal spray technology high-velocity oxygen fuel (HVOF) was used to deposit NiCoCrAlY as a bond coating between the titanium alloy substrate and top 8 wt% yttria-stabilized zirconia thermal-barrier coating (TBC) deposited by electron beam-physical vapor deposition (EB-PVD). The thermal cycling and isothermal exposure tests were conducted to evaluate the durability of the TBC. Investigations using OM, SEM, EPMA, and XRD revealed that the thermal-sprayed BC makes the TBC more durable in isothermal exposure tests but more short-lived in thermal cycling tests, in comparison to our previous study in which the BC was prepared by EB-PVD. This is because the thermal-sprayed imperfections, such as microcracks and voids, elevate the diffusion resistance and degrade the mechanical properties of the BC, simultaneously. To current TBC systems in which the BC is deposited by HVOF, thermal failure behaviors—such as the formation of the Ti/Al mixture oxides at some individual places in the BC, and the Ti2Ni gaps formed around the BC/substrate interface—were also discussed.
