1. 1. Performance of High-temperature Coatings : Oxidation and Interdiffusion

   Författare :Xiaoyu Sun; Ru Lin Peng; Johan Moverare; Xin-Hai Li; Lindwall Greta; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; coating; diffusion; phase transformation; oxidation;

   Sammanfattning : The use of aluminiferous coatings profoundly improves the service life of superalloys but leads to the microstructural degradation of superalloys and thus the loss of mechanical properties. To solve this trade-off, two strategies were employed in this research. LÄS MER

3. 2. Performance of MCrAlX coatings : Oxidation, Hot corrosion and Interdiffusion

   Författare :Pimin Zhang; Ru Lin Peng; Xin-Hai Li; Sten Johansson; Ping Xiao; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : MCrAlY coatings (M=Ni and/or Co) are widely used for the protection of superalloy components against oxidation and hot corrosion in the hot sections of gas turbines. The drive for coating systems to bestow adequate oxidation and corrosion resistance upon the components becomes urgent as an inevitable result of the necessary improvement in engine combustion efficiency and service lifetime.

4. 3. Interphases in Polymer Blends

   Författare :Hans Eklind; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; morphology; interdiffusion; compatibilization; characterization; interfacial interaction; mobility; micromechanical transition; dynamic mechanical properties; interphase; polymer blend;

   Sammanfattning : The blending of polymers is a useful means of combining and improving the properties of already existing polymers in the development of new materials at reasonable cost. As most polymers are immiscible with each other, heterogeneous blends are often formed. The properties of such blends are strongly determined by the properties of the interphase. LÄS MER

5. 4. Amorphous, Nanocrystalline, Single Crystalline: Morphology of Magnetic Thin Films and Multilayers

   Författare :Andreas Liebig; Björgvin Hjörvarsson; Gabriella Andersson; Frank Klose; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Multilayer; Superlattice; X-ray diffraction; X-ray reflectometry; electron diffraction; Rutherford backscattering spectrometry; Interdiffusion; thin film growth; transmission electron microscopy; Epitaxial growth; Fysik; Physics; Fysik;

   Sammanfattning : Properties of magnetic thin film devices cannot be understood without detailed knowledge of their structure. For this purpose, a variety of thin film and multilayer systems have been studied. LÄS MER
