Abstract

Cizek, L. Study of CVD coatings used for cutting tools carbide, properties and application areas: VSB – Technical University of Ostrava, Faculty of Mechanical, Department of Mechanical Technology, Thesis, leader: Doc. Ing. Jitka Podjuklova, CSc.

In my thesis I focus on one type of thin coatings, CVD (Chemical Vapor Deposition), in the area of cutting tools. These tools are in most cases inserts from sintere carbide used in turning and milling. In the introduction, we get familiar with history of coating and sintered carbide, then we focus on principle of this method and description of coatings types, their properties and application areas. In the practical part, I compared properties of three samples with CVD. Composition and thickness of each layer, adhesion re-sistance of coating to thermal crakcs were analysed and its hardness was measured. At the end inserts were subjected to the durability test in milling. Description, documenta-tion and results are listed at the end of this work.
