Tungesten Carbide-Cobalt is widely used as coating materials in the aerospace, gas turbibe and automotive industry.Heated coating particles impact upon the substrate at very high speed cause deformation to the substrate surface.Most of the application uses steel material as a substrate.The impact of particle creates small stress fields, which depend upon the state of the spraying material in the injector gun [2].The temperature of flame is between 2300°C and 3000°C [4].
Its complicated to analyze how single particle behave at the time of impact.This study considering substrate as a rigid material .The present work is divided into two parts.
The material data for Tungsten Carbide-Cobalt is taken from METCO/Perkin Elmer Materials Guide 2001 Diamalloy 2003[5], the average particle size being 45 micron.

For most clinical applications, the choice of scaffold material and structure is crucial [1].
When cells have attached to the material surface there must be enough space and channels to allow for nutrient delivery, waste removal, exclusion of material or cells and protein transport, which is only obtainable with an interconnected network of pores [2].
In addition to the structural properties of the material, physical properties of the material surface for cell attachment are essential.
Materials and Methods Polymer Scaffolds Fully reticulated polyester based polyurethane foams of 45 and 60 ppi (Bulbren S, Eurofoam GmbH, Wiesbaden, Germany) were used in this study.

Effect of annealing temperature on the soft magnetic behavior of Sendust powder core Wei Ding 1, a, Wang Xian1, b※, Feng Ze-kun1, c, Gong Rong-zhou1, d 1School of Optical and Electronic Information, Huazhong University of Science & Technology, China aDing.Wei@smail.hust.edu.cn, bwangx@mail.hust.edu.cn, cfengzekun@mail.hust.edu.cn, drzhgong@mail.hust.edu.cn Keywords: powder core, annealing temperature, effective permeability, quality factor Abstract.
These component materials offer several advantages over traditional laminated steel and soft magnetic ferrite cores in some applications.
Insulating materials may be divided to organic and inorganic materials, phosphate system insulation has been concerned due to its high electrical resistivity, oxidation resistance and also it does not influence the consolidation behavior of soft magnetic powders [13, 14].

In epitaxial graphene research, people usually disregard SiC as active material.
The ohmic contact to low-doped 6H-SiC can be explained by the low energy barrier of FB = 0.3 eV between epitaxial graphene and 6H-SiC [4] resulting from the work functions of both materials.

Introduction Concerning electronic excitation, many important systems show anisotropy such as familiar layered materials like graphite[1] and BN[2], non-central symmetric semiconductor compounds such as GaN[3], superconductors such as YBaCuO[4] and MgB2[5].
Some nanostructures such as nano-tubes and nano-onions can be considered as roll-up versions of layered materials (Fig.1a), so the local anisotropy also changes with position inside the nano-structured material.
