Self-aggregated Li4Ti5O12 particles sandwiched between graphene nanosheets (GNSs) and single-walled carbon nanotubes (SWCNTs) network are reported as new hybrid electrodes for high power Li-ion batteries. The multi-layer electrodes are fabricated by sequential process comprising air-spray coating of GNSs layer and the following electrostatic spray (E-spray) coating of well-dispersed colloidal L...

TiO2 coatings deposited using reactive magnetron sputtering and spray coating methods, as well as Agand Mo-doped TiO2 coatings were investigated as self-cleaning surfaces for beverage processing. The mechanical resistance and retention of the photocatalytic properties of the coatings were investigated over a three-month period in three separate breweries. TiO2 coatings deposited using reactive ...

Wear of the surface is the major problem of all materials. This wear can be of many types and there can be several methods of reducing wear. Coating on the surface of material is one of them. On M.S substrate, thermal spray coating is done using Detonation spray gun and coating powders used is a mixture of oxides (Al2O3-13TiO2). The thermal-sprayed coatings are characterized by SEM, EDS analyse...

titanium and its alloy are known as important load-bearing biomaterials. the major drawbacks of these metals are fibrous formation and low corrosion rate after implantation. the surface modification of biomedical implants through various methods such as plasma spray improves their osseointegration and clinical lifetime. different materials have been already used as coatings on biomedical implan...

Fe-based amorphous/nanocrystalline coatings were prepared on the AISI 321 steel substrate by the high-velocity oxygen-fuel (HVOF) thermal spraying technology. The effect of selected parameters (oxygen flow, kerosene flow and spray distance) on the cavitation erosion resistance (denoted as Rc) of the coating were investigated by using the Taguchi method. Statistical tools such as design of exper...

In this study, the newly designed bipolar plate for proton exchange membrane fuel cells (PEMFC) was produced by spray-coating the Ni65Cr15P16B4 metallic glassy alloy on Al plate. The Ni65Cr15P16B4 metallic glass was adopted as a coating material because of its excellent corrosion resistance and the high velocity oxy-fuel (HVOF) spray coating was used for the metallic glass deposition on the Al ...

Plasma spray process is one of the most versatile thermal spray deposition processes. There are great number of parameters that influence the quality and characteristic of deposited coating and their values must be defined precisely for each type of coating and used equipment individually. A review of the technology developed for deposition of ferrous-based powder spray (Fe-1.3Cr-1.5Mn-1.2C0.3N...

Zinc oxide thin-films are prepared either by spin coating of an ethanolic dispersion of nanoparticles (NP, diameter 5 nm) or by spray pyrolysis of a zinc acetate dihydrate precursor. High-resolution electron microscopy studies reveal a monolayer of particles for the low temperature spin coating approach and larger crystalline domains of more than 30 nm for the spray pyrolysis technique. Thin-fi...

The purpose of this research was to study the aqueous-based film coating of tablets utilizing a laboratoryscale side-vented perforated pan-coating apparatus. The process parameters of potential importance with respect to the final film quality were evaluated by using trial and error method. Tablets were evaluated for coating uniformity (mg), coating process efficiency (%), surface roughness, an...

Cold spray coatings are considered promising for surface protection of light metal substrates but the mechanisms of bonding and coating build-up are still poorly understood and are the subject of continuing debate. A variety of coating/substrate combinations have been characterised in detail using electron microscopy to examine the nature of the interparticle and particle/substrate interfaces. ...
