The cold spraying of ceramic materials is widely acknowledged as a difficult process because it necessitates the feedstock powder particles experiencing plastic deformation for deposition on substrate. problem arises due to brittle properties such titanium dioxide (TiO2), combined with lack understanding bonding mechanisms. In this study, TiO2 coatings were deposited onto copper and aluminum su...

Laser coating is a material placement technique wherein powder melted using laser to coat portion of substrate. In this study, cladding and its applications are reviewed. First, background the important parameters highlighted. Then, control procedure criticized. As an example process, titanium alloys investigated. Finally, on gas turbine engines, dies drilling spindles, tools, blades

Ion implantation has been shown to improve adhesion strength of AlCrSiN coatings due a synergic enhancement on fracture toughness and load bearing capability the substrate that can potentially increase in-service efficiency coated cutting tools. In this work, deposited by PVD WC-Co substrates implanted with Ti, Cr N ion species have processed. The mechanical properties characterized contact tec...

The present work reports results of an effort to produce a stack multilayer optical filter on a poly(ethylene terephtalate) (PET) substrate, using a PECVD technique. Titanium dioxide type of material (n550 = 2.3) has been selected for high refractive index layers while that of silicon dioxide type (n550 = 1.4) served as low refractive index films. For a synthesis of the former material, titaniu...

Nano-structured TiO2 thin films were deposited onto soda lime glass by the pneumatic spray pyrolysis method from a peroxo-titanium complex solution. Samples were prepared spraying 10 s the complex solution followed by an interruption of 20 s in order to avoid inadequate substrate cooling, the substrate temperature was varied from 230 to 430 oC in 50 °C steps. Amorphous as-deposited films crysta...

We characterize a single titanium (Ti) transition edge sensor (TES) designed for in situ detection of individual He2 ∗ excimers. We find a critical temperature of 420 mK, an electrothermal time constant of ∼3μs, and a total energy resolution of 1.5 eV. We observe the detector response to short laser pulses and present a successful analysis strategy for extracting direct-TES-hit pulses from a mu...

Counter electrodes (CEs) of dye-sensitized solar cells (DSCs) are usually fabricated by depositing catalytic materials on substrates. The poor adhesion of the catalytic material to the substrate often results in the exfoliation of catalytic materials, and then the deterioration of cell performance or even the failure of DSCs. In this study, a highly adhesive surface layer is in situ grown on th...

The anodic TiO2 nanotube (TNT) has been promising as both electrocatalysts in electro-energy synthesis and storage devices, photoelectrocatalysts solar energy conversion devices. active area of the (photo)electrocatalyst materials must be clarified because current density can normalized to an electrochemically surface area. Herein, it is discussed whether TNT electrodes photo- electrochemicial ...

The structure and physical-mechanical properties of Ti-Ni-Ta-based surface alloy synthesized on the TiNi-substrate through additive thin-film electron-beam method have been studied. synthesis was carried out by 30-fold alternation operations deposition a dopant film (Ti 60 Ta 40 (at.%), ~50 nm thick) liquid-phase mixing film/substrate using pulsed low-energy high-current electron beam. It found...
