  1. 1. Mechanical dry grinding process of saw chain

    University essay from Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap; Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Author : Dennis Svensson; Tobias Falk Svärd; [2019]
    Keywords : dry grinding; abrasive; grinding wheel; grinding disc; grinding wheel; friction; energy; work; chainsaw; saw chain; cutting link; cutting edge;

    Abstract : The cutting links on chainsaws needs to be sharpened regularly to retain its sharpness. The most effective way is to use a machine wheel grinder. However, due to high friction there is a high risk of tempering the steel and damaging the sustainability to wear, resulting in a dull cutting edge. READ MORE

  2. 2. Friction and wear study of lean powder metallurgy steel in a lubricated sliding contact

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Caroline Lejonklo; [2019]
    Keywords : Lean steel; Powder metallurgy PM ; Powder metallurgy steel PM steel ; Friction; Wear; Sliding contact; Lubricated; Porosity; Tribology; Adhesive wear; Abrasive wear; Gear; Gear tooth; Particles; Polyalphaolefin 8 PAO 8 ; Contact pressure; Density; Light optical microscopy LOM ; Scanning electron microscopy SEM ; Energy-dispersive X-ray spectroscopy EDS ; Vertical svanning interferometry VSI ; Pin on disc; Pin-on-disc;

    Abstract : A fairly new technology used to produce metallic components is powder metallurgy (PM). Among the advantages with this technique are decreased cost of production for complex-shaped parts, new alloys are made possible, reduced end processing, less material loss, and vibrational damping effects.

  3. 3. 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

  4. 4. Effects of grooving slippery concrete floors on dairy cows´ claw health, behavior, fertility and survival : farmers experience and herd data

    University essay from SLU/Department of Biosystems and Technology (from 130101)

    Author : Stefanie Macklin; [2018]
    Keywords : activity; lameness; slippery; abrasive; oestrus behavior; downer cow; mounting; concrete; mortality; muscle strain; trauma; claw wear;

    Abstract : The most common floor type in dairy barns is concrete. Concrete does unfortunately get slippery over time due to mechanical and chemical degradation. Slippery floors increase the risk of slipping and falling and influence cows’ behavior, which can affect claw health, fertility and survival. READ MORE

  5. 5. Tribological characterisation of turbocharger turbine sealing rings in heavy duty diesel engines

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

    Author : Alex Goussakov; Alin Dumitru Durac; [2018]
    Keywords : Tubine sealing rings;

    Abstract : This work investigated the wear mechanisms of turbocharger components in heavy duty diesel engines. By understanding the wear mechanisms that are occurring in turbochargers the life time of the turbocharger components can be improved. READ MORE
