1. Microstructure and plastic deformation of textured CVD alumina coatings
Sammanfattning : 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. LÄS MER
2. Microstructure and wear mechanisms of textured CVD alumina and titanium carbonitride coatings
Sammanfattning : The aim of this thesis is to find the reasons behind how the wear performance of hard coatings produced by chemical vapor deposition (CVD) is influenced by their texture, as this is today not fully known. Therefore, differently textured coatings were synthesized, and subsequently analyzed both before and after specially designed machining tests. LÄS MER
