13. Nanostructuring and Age Hardening in TiSCN, ZrAlN, and TiAlN Thin Films
Sammanfattning : This thesis explores nanostructuring in TiSiCN, ZrAlN, and TiAlN thin films deposited by cathodic arc evaporation onto cemented carbide substrates, with intended applications for cutting tools. The three systems were found to exhibit age hardening upon annealing, by different mechanisms, into the superhard regime (≥30 GPa), as determined by a combination of electron microscopy, X-ray diffraction, atom probe tomography, erda, and nanoindentation tech- niques.

14. Laser transformation hardening of steel surfaces
Sammanfattning : The process of laser transformation hardening is a complex one to model in that there are a large number of parameters to account for. These include parameters of the process itself, e.g. beam intensity, intensity distribution, beam size, velocity of movement, degree of absorptivity, etc. LÄS MER
15. Effects on Machinability due to Microstructure Variations in Case Hardening Steel
Sammanfattning : Typical products made of case hardening steel are transmission parts like gear wheels, pinions and crown wheels. Case hardening produces a carbon-rich surface and provides the parts with both enhanced hardness and fatigue life. LÄS MER
