  1. 1. High temperature galling influencing parameters and mechanisms

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Leonardo Pelcastre; Luleå tekniska universitet.; [2013]
    Keywords : Machine Elements; Maskinelement;

    Abstract : Damage of forming tools at elevated temperatures is a major problem in metal forming processes such as hot stamping. Of special importance is the occurrence of adhesion and gross material transfer from the work-piece to the tool surface, a phenomenon known as galling. READ MORE

  2. 2. On high temperature oxidation resistance Towards the materials genome of high temperature alloys

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Samuel Hallström; KTH.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials Science and Engineering; Teknisk materialvetenskap;

    Abstract : The efficiency of a heat engine increases with increasing service temperature. This leads to a demand for material that can withstand aggressive environments and sometimes also high load at higher and higher temperature. That is the rationale for the work of this thesis. READ MORE

  3. 3. High Temperature Wear Processes

    University dissertation from Luleå tekniska universitet

    Author : Sinuhe Hernandez; Luleå tekniska universitet.; [2014]
    Keywords : Machine Elements; Maskinelement;

    Abstract : Moving machine assemblies are increasingly exposed to extreme operating conditions involving high temperatures owing to demands on higher power densities, high performance/efficiency and extreme environments. The changes in surface and near surface properties of contacting surfaces caused by exposure to high temperature and deformation govern the occurrence of friction, wear and material transfer of the tribological system.

  4. 4. High Temperature Corrosion in Fluidised Bed Environment

    University dissertation from Chalmers University of Technology

    Author : Anna Nafari; Chalmers tekniska högskola.; Chalmers University of Technology.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ytbehandlingsteknik; Surface engineering; High temperature corrosion; loop seal; CFB; coatings; erosion corrosion test rig; SO2; HCl; Ni and iron based alloys; surface characterization and temperature gradient;

    Abstract : Successful material selection for power plants is the result of understanding the environment in each boiler. The boiler environment is affected by fuel chemistry, co-firing, process control and deposits as well as boiler type, design, size and load. READ MORE

  5. 5. Effects of Reject Refining at High Temperature on TMP Fibre Properties
