  1. 1. Atomic wear mechanisms of hard chrome against Al2O3

    University essay from Malmö universitet/Fakulteten för teknik och samhälle (TS)

    Author : Raul Fierro Tobar; Marius Yuku; [2021]
    Keywords : Wear mechanisms; DFT; MD; hard chrome; aluminium; RDF; adhesive; abrasive; Nötning; DFT; MD; hårdkrom; aluminium; RDF; adhesiv; abrasiv;

    Abstract : Hard chrome exhibit hardness of about 70 HRC and lubricity that prevents seizing and galling and is therefore the common first choice for engineers to reduce friction and minimize wear. These properties enable engineering applications such as cutting and drilling, especially in manufacturing, production and consumer good industries. READ MORE

  3. 2. An Investigation into 'Squeezing'or Three-Body Wear caused by Abrasive Particles

    University essay from KTH/Materialvetenskap

    Author : Vinayak Ramakrishnan Easwar; [2020]
    Keywords : ;

    Abstract : Material wear is an ever present phenomenon and can never be completely removed in systems of moving parts. There will always be friction between materials, causing degradation of these materials and eventually the material will be worn out and have to be replaced. READ MORE

  4. 3. Wear testing of high-alloy carbon steel used in mining tools

    University essay from KTH/Materialvetenskap

    Author : Sara Olsson; Linn Efsing; [2013]
    Keywords : Wear; Wear-testing methods; Adhesive wear; Abrasive wear; Nötning; Nötningstester; Adhesiv nötning; Abrasiv nötning;

    Abstract : Wear is a commonly occurring degradation mechanism for materials and components in the rock drilling industry. The wear can occur by either abrasion or adhesive wear. Further corrosion and presence of water or other lubricating fluids with or without particles may influence the behavior. READ MORE

  5. 4. Alternative materials for high-temperature and high-pressure valves

    University essay from Karlstads universitet/Fakulteten för teknik- och naturvetenskap

    Author : Linda Almström; Camilla Söderström; [2010]
    Keywords : tribology; wear; valve; adhesion; abrasion; coating;

    Abstract : AB SOMAS Ventiler manufactures valves for different applications. A valve of type DN VSSL 400, PN 100, used in high-temperature and high-pressure applications was investigated in this thesis. This type of valve is coated with high cobalt alloys to achieve the tribological properties needed for this severe condition. READ MORE
