1. 1. Effect of temperature on early stage adhesion during TiAlN sliding against Inconel 718 and Stainless steel 316L : High temperature tribology

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Ahsan Ali; [2023]
   Keywords : High temperature tribology; Early-stage adhesion; Adhesive wear; Friction; Wear resistant coatings; Physical vapour deposition PVD coatings; TiAlN; Tungsten carbide WC Co ; Difficult to machine super alloys; Inconel 718; Stainless steel 316L; High-performance materials; Abrasion; Oxidation; Chipping; Ploughing; Characterization;

   Abstract : High-performance materials such as stainless steels and nickel based super alloys are widely used in demanding applications where high mechanical and thermal properties are required. The applications of super alloys are mainly found in jet engines, power plants and gas turbines demanding high fatigue strength, corrosion and oxidation resistance as well as wear resistant properties.

3. 2. Investigation of the Microstructure of Plastically Deformed Cemented Carbide

   University essay from KTH/Materialvetenskap

   Author : Felicia Larsson; [2023]
   Keywords : ;

   Abstract : During machining operation, cemented carbide tools are exposed to high loads and temperatures, which eventually leads to plastic deformation of the tool material. The aim of this work was to investigate if the microstructures of creep deformed micro grain cemented carbides can be linked to alloying elements and mechanical properties. READ MORE

4. 3. Effect of post-treatment of cemented carbide : Microstructural investigation and evaluation of mechanical properties of cemented carbide inserts for rock tool applications

   University essay from Karlstads universitet/Avdelningen för maskin- och materialteknik

   Author : Jessica Jacobs; [2021]
   Keywords : ;

   Abstract : Cemented carbides are used in rock tool applications by reason of their beneficial mechanical properties, i.e. a combination of high toughness, wear resistance and hardness. The cemented carbides commonly receive their hardness from tungsten carbides (WC) whereas cobalt (Co) is the dominating binder material. READ MORE

5. 4. Effect of carbon activity on microstructure evolution in WC-Ni cemented carbides

   University essay from KTH/Materialvetenskap

   Author : Olivia Danielsson; [2018]
   Keywords : Cemented carbides; Hard metal; WC-Ni; Tungsten carbide; Nickel binder; Grain coarsening; Grain growth; Carbon activity; Size distribution; EBSD; Electron backscattered diffraction;

   Abstract : The aim of this work was to systematically study how the microstructure evolution is affected by the carbon activity in WC-Ni cemented carbides. Seven WC-9.59at%Ni alloys with different carbon activity were sintered at 1500 °C. READ MORE

6. 5. Effect of tungsten carbides properties of overlay welded WC/NiSiB composite coatings

   University essay from KTH/Industriell produktion

   Author : Richard Seger; [2014]
   Keywords : ;

   Abstract : To get a long life of a product which is subjected to heavy mechanical wear, materials with particularly good properties such as high hardness and the ability to resist high temperature is required. Tungsten carbide is a material which has these properties, but to manufacture large products for mining industry or agriculture entirely of this material is neither practical nor quite beneficial when the disadvantages of the materials such as brittleness, high weight and high price will have a major affect.
