   Författare :Milou Göransson; [2023]
   Nyckelord :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.;

   Sammanfattning : 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. LÄS MER

3. 2. Evaluation of Refined Tribological Properties of Diamond Coated Cutting Tools Used in Machining of High-Strength Aluminum Alloys : Master thesis report regarding refined frictional & wear behavior of uncoated & CVD diamond coated WC-Co cemented carbide cutting tools used for machining of Al 7xxx alloys.

   Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

   Författare :Christian Hultman; [2022]
   Nyckelord :tribology; machining; metal cutting; turning; milling; friction; wear; material transfer; surface technology; tribologi; skärande bearbetning; svarvning; fräsning; friktion; förslitning; nötning; materialöverföring; ytteknologi;

   Sammanfattning : High strength aluminum alloys have for a long time been a popular material utilized in the automotive and aerospace sector due to coveted mechanical properties in terms of weight, strength, fatigue, and corrosion. However, tribological mechanisms such as tribo-film formation and material transfer during the metal cutting manufacturing process of aluminum impose significant reduction of machining and tool-life performance.

   Författare :Sebastian Öhman; [2016]
   Nyckelord :Wear; Alumina; Al2O3; Coating; Coated; coatings; Tools; Cutting tool; Cemented Carbide; Inclusions; Steel; Steels; SS2541; Sandvik; Coromant; Nötning; Förslitning; Aluminiumoxid; Al2O3; Beläggning; Ytbeläggning; Tunnfilm; Tunnfilmsteknik; Verktyg; Skärverktyg; Hårdmetall; Inneslutning; Stål; SS2541; Sandvik; Coromant; Deformation;

   Sammanfattning : In this master thesis, performed at Sandvik Coromant Västberga (Stockholm), a comprehensive study has been made to investigate the wear on textured alumina (Inveio™) coated cutting tools when turning low-alloy steels. Specifically, wear studies have been made on tools’ rake faces when turning two separate batches of SS2541, after an initial turning time of 4 min. LÄS MER
