1. 11. Tribological behaviour of CVD diamondcoated tools during machining of highstrength aluminum alloy : Master thesis project on tribological behavior of super hard materials: chemicalvapor deposition diamond (CVD) coated cutting tools and polycrystalline diamond(PCD) cutting tools used in machining of high strength aluminium alloy

   University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

   Author : Oskar Lundquist; [2022]
   Keywords : CVD diamond coating; CVD; Aluminum machining; Tool coatings; PCD; diamond coating; diamond; Tribology; Material Science.;

   Abstract : Machining of Aluminum can be complicated due to large amounts of adhesion and diffusion of the aluminum onto the cutting tool, causing effects such as built-up layers and built-up edges. This leads to poor surface finishes and can significantly affect the tool life. READ MORE

3. 12. Design and validation of the control systemfor a Pin-on-Disc Machine

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : SIMON CALMINDER; JONAS XU; [2021]
   Keywords : Pin-on-Disc; Tribometer; Model; PID; Control; Pinne-skiva; Tribometer; Modell; PID; Reglersystem;

   Abstract : The friction between the under-head of a bolt and the mounting surface affects the necessary torque from a tightening tool. To study the friction behaviour during a highly dynamic tightening process, a Pin-on-Disc testrig has been developed. READ MORE

4. 13. Tribological characterisation of additively manufactured hot forming steels

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

   Author : Anna Vikhareva; [2020]
   Keywords : High temperature tribology; additive manufacturing; hot stamping; maraging steel; H13; galling;

   Abstract : Over the last decade, the application of ultra-high strength steel as safety components and structural reinforcements in automobile applications has increased due to their favourable high-strength-to-weight ratio. The complex shaped components are widely produced using hot stamping. READ MORE

5. 14. Material Transfer Mechanisms during Interaction of Aluminium Alloy and Tool Steel at Elevated Temperatures

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

   Author : Gabriel Macêdo; [2020]
   Keywords : material transfer mechanisms; high temperature tribology; hot metal forming tribology; hot-stamping of aluminium alloys; aluminium alloys;

   Abstract : Hot stamping of aluminium alloys allows for increased formability, decreased springback and the possibility of integrating age-hardening heat treatments into the process. However, it can be challenging due to the occurrence of material transfer of aluminium onto the tool, as aluminium is prone to adhesion even at low temperatures. READ MORE

6. 15. Design of a Tribometer to Study Friction inThreaded Fastener Interfaces

   University essay from KTH/Maskinkonstruktion (Inst.)

   Author : Zhan-Jun Lin; [2020]
   Keywords : tribometer; friction coefficient; tightening; pin-on-disc; tribometer; friktionskoefficient; åtdragning av skruvförband; pin-on-disc;

   Abstract : Bolts and nuts are one of most common joining methods since they are simple and low-cost to connect parts. Appropriate clamp force from bolted joint remains resultant joints secured, but higher/lower preload on bolted joint increases risk of the failure of mechanism. READ MORE
