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. Influence of pulsing on PVD TiAlN coating microstructure and mechanical properties : Master thesis project on the impact of deposition parameters on performance and properties of PVD titanium aluminum nitride.

   University essay from Karlstads universitet

   Author : Marcus Roseen; [2023]
   Keywords : ;

   Abstract : This thesis investigates the influence of pulsing on the mechanical properties of PVD TiAlN coatings. The thesis focuses on defects caused by droplets during the arc-evaporation technique by altering the duty time, which affects mechanical properties. READ MORE

4. 3. SFEER Hydrogen Permeation : Finding a suitable coating for the PA6 liner

   University essay from Uppsala universitet/Institutionen för materialvetenskap

   Author : Elsa Friis; Klara Karlsson; Rebecka Damgren; Emma Åkesson; Malin Johansson; [2023]
   Keywords : Hydrogen permeation; PA6; coating; hydrogen permeation barrier; polymer hydrogen permeation; permeation; protective coating; hydrogen embrittlement;

   Abstract : Water Stuff & Sun are developing a hydrogen battery based on a technology called SFEER’s. The SFEER’s are spherical high-pressure gas storage containers that are the size of a tennis ball. They consist of a carbon fiber-shell that is lined on the inside with a polymer called PA6.

5. 4. Multivariate Data Analysis on (Ti,Al)N Arc-PVD coating process : MVDA of the growth parameters thickness, stress,composition, and cutting performance

   University essay from Uppsala universitet/Oorganisk kemi

   Author : Per-Olof Öqvist; [2021]
   Keywords : chemistry; material; coating; statistics; PLS; PCA; kemi; material; beläggning; statistik; PLS; PCA;

   Abstract : This diploma work was done at Seco Tools AB (SECO) in Fagersta and aimed to evaluate the possibility to model the relationship between deposition data, deposition properties and, cutting performance of a (Ti,Al)N coating on cutting inserts by applying the Multivariate Data Analysis (MVDA) modeling technique Partial Least Squares Projection to Latent Structures Modeling (PLS). Cathodic Arc Deposition (Arc-PVD) was the PVD technique focused on this study. READ MORE

6. 5. Erosion Behaviour of Thermal Barrier Coatings

   University essay from Linköpings universitet/Konstruktionsmaterial

   Author : Caroline Wännman; [2021]
   Keywords : erosion; TBC; APS; EB-PVD; PS-PVD; failure mechanisms;

   Abstract : Thermal barrier coatings (TBCs) are advanced material systems used in the hot sections of gas turbines. The TBCs are designed to provide insulation against hot gases by a ceramic top coat and to provide oxidation and corrosion resistance by a metallic bond coat. READ MORE
