  1. 1. A GREENER SOLUTION Investigating the potential use of Green Solvents to remove cellulose nitrate lacquer from silver objects

    University essay from Göteborgs universitet/Institutionen för kulturvård

    Author : Borén Evelina; [2022-07-05]
    Keywords : Sustainable Conservation; Green Solvents; Cellulose Nitrate; Lacquer; Coating; Silver;

    Abstract : This thesis investigates the performance of non-hazardous solvent substitutes, so called “Green Solvents", for the removal of aged and unaged cellulose nitrate lacquer from silver surfaces. Literature research and preliminary tests resulted in four solvents of interest: ethyl acetate, ethyl lactate, propylene carbonate and dimethyl carbonate. READ MORE

  3. 2. Method development for the use of Smoothed-particle hydrodynamics simulations for vehicle soiling analysis

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Josep Plana Riu; [2022]
    Keywords : ;

    Abstract : An increasing amount of sensors is being placed in cars in order to monitor their vicinities, which performance is highly dependant on the driving conditions, in which weather has a big role, and thus water contamination is a topic that will increase its importance in the future of the car industry. One of these sources of contamination is self-soiling: how cars get dirty because of their own tires. READ MORE

  4. 3. Improvement and Development of Powder Spreadability Testing

    University essay from KTH/Materialvetenskap

    Author : Fabrice Rosala; [2021]
    Keywords : ;

    Abstract : With rising interest in metal additive manufacturing and, specifically, in powder bed fusion processes, it is essential to understand relevant process parameters and the behavior of powders used in such processes. At the time of writing, the flow behavior of powders is in the spotlight whereas little research into the spreadability of a powder is being conducted. READ MORE

  5. 4. Design and Calibration of Pneumatic Probes for Aerodynamic Testing

    University essay from KTH/Farkostteknik och Solidmekanik; KTH/Kraft- och värmeteknologi

    Author : Angelica Lejdeby; [2021]
    Keywords : ;

    Abstract : To develop turbomachines aerodynamic testing is an important part of the process. The performance testing this thesis will focus on is pressure measurements, which often is done using pneumatic probes. The pneumatic probes used in this project were a five-hole probe, a pitot probe and two different types of Kiel probes. READ MORE

  6. 5. Method to assess machinability of engineering steels using coated carbide tools

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Petra Hedberg; [2021]
    Keywords : Machinability; tool wear; coated carbide; non-metallic inclusions; Ca-treated; steel; 42CrMo4;

    Abstract : In this master thesis, performed at Ovako Group R&D (Hofors) a new machining test method for ranking heats of calcium-treated steels, M-Steels, has been proposed.  A total of six different heats of 42CrMo4-M steel in the quenched-and-tempered (Q+T) condition were tested. READ MORE
