  1. 1. High temperature tribological evaluation of a self-lubricating laser cladding with and without external solid lubricant

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

    Author : Cecilia Nemeth; [2020]
    Keywords : high temperature tribology; hot metal forming of aluminium; self-lubricating laser cladding; external solid lubricant;

    Abstract : The purpose of the project work was to build knowledge of the tribological behaviour of self-lubricating laser cladding, with and without external solid lubricant during conditions relevant for hot metal forming of aluminium. The materials used during the project were plates coated with a Ni-based self-lubricating clad and a reference sample of work tool steel. READ MORE

  2. 2. Use of compliant mechanisms in gearbox applications

    University essay from Högskolan i Skövde/Institutionen för ingenjörsvetenskap; Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Author : Álvaro Manresa Pérez; Ander Gonzalez Sanchez; [2020]
    Keywords : compliant mechanisms; product development; Finite Element Analysis; additive manufacturing;

    Abstract : The purpose of this thesis is to prove that the use of compliant mechanisms in gearbox applications is viable. Compliant mechanisms are developed for their implementation in Scania’s hybrid asynchronous gearboxes. READ MORE

  3. 3. Mapping and characterisation of surface damage and wear mechanisms in gun barrels : Gun barrels exposed to cyclic thermo-mechanical loading

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Martin Perkovic; [2020]
    Keywords : Wear; erosion; sliding wear; gun barrel; characterisation;

    Abstract : Gun barrels are an important component in advanced defence systems. The gun barrels are used for direct and indirect fire and the material of the gun barrel is exposed to great strains and high temperatures. This sets high demands on the material of the gun barrel. During firing the gun barrel can be damaged. READ MORE

  4. 4. Synovial fluid components as synergistic lubricants in articular joint models

    University essay from KTH/Kemi

    Author : Sixuan Li; [2019]
    Keywords : synergistic lubrication; synovial fluid; biolubrication; DPPC; hyaluronic acid; Mini-Traction Machine; macro- and microscale; profilometer;

    Abstract : The excellent lubrication present within mammalian synovial joints attracted scientific interest, and some close-to-realistic models were applied to study the mechanism in vitro. In this project, the synergistic lubrication of synovial fluid was investigated by using 1,2-Dipalmitoyl-sn-glycero-3-phosphatidylcholine (DPPC), hyaluronic acid (HA), and phosphate-buffered saline (PBS buffer) to mimic the synovial fluid.

  5. 5. High Temperature Tribology in Hot Stamping

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

    Author : Evan Kurnia; [2019]
    Keywords : high temperature tribology; hot stamping; acoustic emission; condition monitoring; hardfacing;

    Abstract : Many automotive components are made of Al-Si coated ultra-high strength boron steel (UHSS) and are produced by hot stamping process. In this process, the workpiece is heated to an austenitizing temperature and is then formed and quenched simultaneously between the tools to achieve the desired shape and high strength. READ MORE
