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...

Different layered ZnO/MEH:PPV composite solar cells have been fabricated to assess the role of the ZnO backing layer on the open circuit voltage of nanowire composite solar cells. Comparisons between cells using a ZnO layer prepared by spray pyrolysis and by sputtering and oxidising a Zn layer are compared. Cells with a sputtered Zn layer which is then oxidised show a significantly improved ope...

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...

Carbon coated porous hollow Na2FePO4F (C/Na2FePO4F) spheres with 500 nm diameter and 80 nm wall thickness are synthesized by a one-step template-free ultrasonic spray pyrolysis process using sucrose as the carbon source. Nano-sized porous hollow C/Na2FePO4F spheres allow electrolyte to penetrate into the hollow structure, and thus the electrochemical reaction can take place on both the outside ...

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...

The olivine structured mixed lithium-transition metal phosphates LiMPO4 (M = Fe, Mn, Co) have attracted tremendous attention of many research teams worldwide as a promising cathode materials for lithium batteries. Among them, lithium manganese phosphate LiMnPO4 is the most promising considering its high theoretical capacity and operating voltage, low cost and environmental safety. Various techn...
