By its nature, plasma spraying is a rapid solidification process in which finely powdered material injected into jet almost instantly melted and propelled with high velocity, created by strong magnetohydrodynamic force against suitable surface [...]

     In this study, hydroxyapatite was coated on titanium substrates by plasma spraying process. A well-known porous and lamellar microstructure was found in the lateral a...

Introduction The possibility of application of electric probes for diagnostics of thermal plasma jets is limited, especially due to the interaction of the probe with plasma. Nevertheless, some important information can be obtained. Electric probes were used for measurement of plasma potential in arc plasma [Chapman and Jones, 1978; Hrabovský and Konrad, 1991; Popov and Gateval, 2001], and for d...

Nanostructured ceramic coatings produced by plasma spray processes are being developed for a wide variety of applications that require resistance to wear, erosion, cracking and spallation [1]. In addition the process is being developed to make near net shaped ceramic performs by dissolution of the substrate after spraying. Attractive properties associated with a nanostructure (in general referr...

Thermal barrier coatings (TBCs) deposited by suspension plasma spraying (SPS) are recognized as a potent method to increase efficiency and extend the life of gas turbines. The unique microstructure SPS provides exceptional mechanical thermal properties, but on other hand, affects sintering TBCs what could lead undesirable changes in properties premature failure. This study attempts characterize...

To determine the efficacy and underlying mechanism of Astragalus polysaccharides (APS) on plasma lipids in hypercholesterolemia hamsters. The effect of APS (0.25 g/kg/d) on plasma and liver lipids, fecal bile acids and neutral sterol, cholesterol absorption and synthesis, HMG-CoA reductase activity, and gene and protein expressions in the liver and small intestine was investigated in twenty-fou...

Metallic glass has excellent functions such as high strength and high corrosion resistance. Therefore, it is one of the most attractive materials, and various developmental research works have been conducted by many researchers. However, the metallic glass material is expensive to use, and a composite material is preferred for the industrial application. Thermal spraying method is one of potent...
