1. Microstructure and Wear of CVD Coatings used in Metal Cutting Applications
Abstract : 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. READ MORE

2. Microstructure of Alumina (Al2O3) Grown by Oxidation of FeCrAl Alloys and by Chemical Vapour Deposition
Abstract : This thesis consists of two parts: the detailed microstructure of (i) CVD alumina multilayer coatings, and (ii) alumina scales formed on three different FeCrAl alloys. The coatings and oxide scales were characterized by using analytical electron microscopy and different surface analysis techniques. READ MORE

4. CVD on Iron Powder - Using Fluidising Bed Techniques
Abstract : Today's electrical energy conversion devices, such as motors, transformers, inductors and generators, are based on laminated magnetic cores for reduction of eddy current losses, imposing a two-dimensional magnetic flux distribution. Using a three-dimensional magnetic flux distribution while maintaining low magnetic losses requires new approaches to magnetic core materials. READ MORE

5. Microstructure and plastic deformation of textured CVD alumina coatings
Abstract : It is known that the wear performance of α-alumina coatings produced by chemical vapor deposition (CVD) is significantly influenced by the type and degree of texture. However, the main reasons behind this behavior are not fully understood. This thesis contains studies of two related topics for increasing the understanding of α-alumina coatings. READ MORE
