  2. 1. Microstructural, Mechanical and Tribological Characterisation of CVD and PVD Coatings for Metal Cutting Applications

    Author : Mikael Fallqvist; Staffan Jacobsson; Mikael Olsson; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tribology; Friction; Wear; Coatings; CVD; PVD; Alumina; Metal cutting; Teknisk fysik med inriktning mot tribomaterial; Engineering Science with specialization in Tribo Materials; Steel Forming and Surface Engineering;

    Abstract : The present thesis focuses on characterisation of microstructure and the resulting mechanical and tribological properties of CVD and PVD coatings used in metal cutting applications. These thin and hard coatings are designed to improve the tribological performance of cutting tools which in metal cutting operations may result in improved cutting performance, lower energy consumption, lower production costs and lower impact on the environment.

  4. 2. Microstructure and Wear of CVD Coatings used in Metal Cutting Applications

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

    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
