1. 21. Controlled interlayer between titanium carbon-nitride and aluminiumoxide

   University essay from Institutionen för materialkemi

   Author : Sara Munktell von Fieandt; [2011]
   Keywords : Aluminium oxide; titanium oxide; titanium carbon-nitride; Chemical Vapour Deposition; Atomic Layer Deposition;

   Abstract : In the industry of metal cutting tools the conditions are extreme; the temperature can vary thousand degrees rapidly and the pressure can be tremendously high. To survive this kind of stress the cutting tool must be both hard and tough. In order to obtain these properties different coatings are used on a base of cemented carbide, WC-Co. READ MORE

3. 22. Equilibrium Study of Chromium Containing Cemented Carbides : Solubility of chromium in tungsten carbide and η-phase

   University essay from KTH/Materialvetenskap

   Author : Bonnie Lindahl; [2010]
   Keywords : ;

   Abstract : This project treats the W-C-Co-Cr quaternary system at low carbon contents. The main goals with this project were to find a four phase equilibrium between WC, Co-binder phase, η-phase (M6C) and a fourth unknown phase, to discover which the fourth phase is and to establish whether or not WC dissolves any chromium.

4. 23. Characterization of Hard Metal Surfaces after Various Surface Process Treatments

   University essay from Institutionen för fysik, kemi och biologi

   Author : Ali Hakim; [2008]
   Keywords : WC-Co; cermet; grinding; blasting; polishing; residual stress; surface roughness; surface deformations; cross section; adhesion;

   Abstract : The aim of this thesis is to investigate how material surfaces are affected by various surface treatments and how this relates to the adhesion of the coating. The materials that were studied were WC-Co and Cermets and the surface treatments used were polishing, grinding with coarser and finer abrasive grains, and finally wet blasting and dry blasting.
