  1. 1. Effects of Immiscible Compressor Oil in a Flooded PSHE Evaporator : A Visual Study Approach

    University essay from KTH/Energiteknik

    Author : Joel Blomfelt; [2022]
    Keywords : ;

    Abstract : This paper deals with heat transfer in plate evaporators, with a focus on the effects caused by carried-over compressor oil ending up in the heat exchanger. A common standpoint in literature regarding the effect of immiscible oil contamination, in for example an ammonia PHE evaporator, is that the oil can accumulate as a layer on the plate surface causing an additional thermal conduction resistance.

  3. 2. 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

    University essay from KTH/Industriell produktion

    Author : Marco MANGIATERRA; [2018]
    Keywords : Lubricant; Broaching; Cutting Fluid; Tapping; Torque; Smörjning; brotschning; skärvätskor; tappning; vridmoment;

    Abstract : Bearbetningsprocesser är en viktig del av tillverkningsindustrin. Dessa företag måste kontinuerligt förbättra sina processer och göra dem mer effektiva, minska de ekologiska fotavtrycken och driftskostnaderna. Syftet med denna rapport är att förbättra en rund brotschningsprocess för ett bilföretag. READ MORE

  5. 4. Self Lubricating Components

    University essay from Uppsala universitet/Institutionen för teknikvetenskaper

    Author : Simon Tidén; Niklas Levin Bjärnlid; Tim Melin; Daniéla Quist; Filip Selenius Larsson; [2017]
    Keywords : self lubricating; solid lubricant; high speed steel; powder metallurgy; friction; wear; molybdenum disulfide; tungsten disulfide; hexagonal boron nitride; soft metals; copper;

    Abstract : The tribological and mechanical properties are of great importance for a material’s lifetime, since it is highly dependent on these two factors. The purpose of this report was to examine suitable solid lubricants for Erasteel, a company that manufactures hot isostatic pressed high speed steels, that will enhance the tribological properties of their steels without worsening the mechanical properties.
