  1. 1. Microstructure evolution of Ti-based and Cr cathodes during arc discharging and its impact on coating growth

    Författare :Jianqiang Zhu; Magnus Odén; Johanna Rosén; Lars Hultman; Flavio Soldera; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : This thesis explores the microstructure evolution of cathodes with various material compositions and grain sizes during cathodic arc evaporation processes as well as the impact on the arc movement, and the microstructure and properties of the deposited nitride coatings. The studied cathode material systems include conventionally metal forged Ti and Ti -Si cathodes, novel Ti3SiC2 MAX-phase cathodes, and dedicatedly designed powder-metallurgical Ti-Si and Cr cathodes with different grain size.

    Sammanfattning : This thesis aims to expand the knowledge of fundamental mechanisms that govern the cathodic arc process. The first part of this thesis explores and explains the correlations between a rather unexplored process parameter (i.e. cathode microstructure) and the microstructure of the coatings. LÄS MER
