  3. 7. Microstructure and Wear of CVD Coatings used in Metal Cutting Applications

    Författare :Andreas Larsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MTCVD; Ca-treated steel; EFTEM; CVD; TEM; Ti C; alfa-Al2O3; gamma-Al2O3; wear; kappa-Al2O3; N ; EELS;

    Sammanfattning : This thesis is concerned with the microstructural characterisation of wear resistant Al2O3 and Ti(C,N)coatings produced by chemical vapour deposition on cemented carbide cutting tools. The investigation focuses on the effect of deposition conditions on the microstructure and the microstructural evolution of the coatings during heat-treatments and metal cutting. LÄS MER

  4. 8. Development and application of advanced electron microscopy techniques for materials in biological systems

    Författare :Pernilla Nevsten; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; multiple-unit drug; EFTEM; EELS; cyanine dye; SSAT; cryo-TEM; virus; TEM; apoptosis; SEM; AFm; α-TCP; apatite; XEDS; TEM grid; microscopy supports;

    Sammanfattning : Theoretically, electron microscopy and scanning probe microscopy offer information on a scale beyond the optical microscope. However, the quality of the micrograph and the obtained information is limited by the sample preparation. LÄS MER

  5. 9. Development of Cermet Microstructures during Sintering and Heat-Treatment

    Författare :Jenni Zachrisson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; APFIM; EELS; cemented carbides; quantitative microanalysis; gradients; N ; TEM; EFTEM; hardmetals; EDX; Ti C; light elements;

    Sammanfattning : The work presented in this thesis is concerned with the microstructure of Ti(C, N) based cermet materials used in cutting tool applications. Several techniques have been used to study the microstructure of cermets, in particular transmission electron micro-scopy in combi-na-tion with energy dispersive X-ray analysis and electron energy-loss spectroscopy, energy-filtered transmission electron micro-scopy, atom-probe field-ion microscopy and scanning electron microscopy.
