1. 1. Investigations of Tool Wear Mechanisms in the Turning of Conventional, Calcium Treated and Ultraclean Steels

   University essay from KTH/Materialvetenskap

   Author : Milou Göransson; [2023]
   Keywords : Clean steel; Ultraclean steel; Longitudinal turning; Cemented carbide cutting tool; Chemical vapor deposition coating; Machinability; Tool wear; Non-metallic inclusions; Rent stål; Ultrarent stål; Längdsvarvning; Hårdmetall skärverktyg; Kemisk ångdeponering beläggning; Bearbetningsbarhet; Verktygsslitage; Icke-metalliska inneslutningar.;

   Abstract : Application of clean and ultraclean steels have shown to provide favourable mechanical properties for bearings and transmission components, specifically regarding fatigue performance, compared to conventional steel grades. Clean steels are characterized by containing a very low level of non-metallic inclusions. READ MORE

3. 2. Modeling and Analysis of the Shot Peening Process : a Study of the Residual Stresses in an Insert using the Finite Element Method

   University essay from Linnéuniversitetet/Institutionen för maskinteknik (MT)

   Author : Hamid Torkaman; [2018]
   Keywords : Shot peening; Residual stresses; Cutting tool inserts; Post-coating treatment; Coated cemented carbide;

   Abstract : Cutting tool inserts are often coated with thin layers either through chemical vapor deposition (CVD) or physical vapor deposition (PVD) processes. In order to have a better wear resistance cutting tools are mostly subjected to post-coating treatment processes. READ MORE

4. 3. Measuring volatile nicotine from electronic cigarettes

   University essay from Lunds universitet/Ergonomi och aerosolteknologi

   Author : Simon Lundegard; [2017]
   Keywords : AMS; denuder; e-juice; electronic cigarettes; NGI; nicotine; SMPS; Technology and Engineering; Chemistry;

   Abstract : This thesis is focused on electronic cigarettes and the formulations (also known as e-juices) associated with these. The reason is that there have been countless studies on the health effects and nicotine delivery of normal cigarettes, but not as much on electronic cigarettes. READ MORE

5. 4. Synthesis of solid solution TiBN coatings by cathodic arc evaporation

   University essay from Uppsala universitet/Tillämpad materialvetenskap

   Author : Johan Nyman; [2017]
   Keywords : ;

   Abstract : The present work is aimed at determining the conditions for which synthesis of coatings composed of solid solution TiBN is possible using cathodic arc evaporation, a member of the physical vapor deposition family of coating techniques. Such coatings are interesting from a machining point of view because they have previously been shown to exhibit excellent tribological properties at elevated temperatures. READ MORE

6. 5. Adhesion of CVD coatings on new cemeted carbides

   University essay from Uppsala universitet/Tillämpad materialvetenskap

   Author : Eric Bojestig; [2016]
   Keywords : cemented carbide; adhesion; alternative binder phase; CVD coating; hard metal;

   Abstract : Steel turning inserts cemented carbides have a binder phase consisting of cobalt (Co). However, in recent years a study from the United States National Toxicity Program (NTP) found that cobalt powder is carcinogenic upon inhalation. The European Union's REACH have therefore also classified cobalt powder as carcinogenic upon inhalation. READ MORE
