  1. 1. Thermoset polymers and coatings subjected to high compressive loads

    Author : Daniel Ståhlberg; Mats Johansson; Gijsbertus de With; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polymers; organic coating; thermoset; mechanical properties; compression; Surface engineering; Ytbehandlingsteknik;

    Abstract : This study describes the mechanical response of thermoset polymers under high compressive loads. The study is divided into two parts. The first part focuses on the behaviour of a powder coating when used in a clamping force joint and how the properties vary when the chemical and physical structure of the coating is changed.

  2. 2. Mechanical characterization and modelling of the fracture behaviour of thin brittle coatings on polymer films

    Author : Marcus Vinícius Tavares da Costa; E. Kristofer Gamstedt; Christoph Kirchlechner; Uppsala universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Brittle coating; Polymer substrate; Crack density; Weibull distribution; SEM; Digital image correlation; Finite element modelling; Energy release rate;

    Abstract : Thin brittle coatings with thickness of a few nanometres deposited on flexible polymer substrates form an interesting material combination for food packaging and flexible electronics. This combination may enhance the barrier performance in carton packages. In flexible electronics, coatings could conduct electricity despite their small thickness. READ MORE

  3. 3. Wear resistant low friction coatings for machine elements

    Author : Olle Wänstrand; Uppsala universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; materialvetenskap; Materials Science;

    Abstract : By the introduction of machine elements made of light metals, e.g. Al or Mg alloys, which are coated with a material providing high wear resistance and low friction coefficient, both economical and environmental benefits can be gained. A high resistance against wear results in increased lifetime and lower costs for spare parts and maintenance. READ MORE

  4. 4. Isothermal low cycle fatigue of uncoated and coated nickel-base superalloys

    Author : Svjetlana Stekovic; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : High strength nickel-base superalloys have been used in turbine blades for many years because of their superior performance at high temperatures. However, the superalloys have limited oxidation and corrosion resistance and to solve this problem, protective coatings are deposited on the surface of the superalloys. READ MORE

  5. 5. ZrN based Nanostructured Hard Coatings : Structure-Property Relationship

    Author : Phani Kumar Yalamanchili; Magnus Odén; Naureen Ghafoor; Emilio Jiménez-Piqué; Jon Andersson; Linköpings universitet; []
    Keywords : ;

    Abstract : Ever since the hard coatings have been introduced, there has been a constant push for better mechanical properties, which motivates for deeper understanding of the microstructure-mechanical properties correlation. The aim of this thesis is to extend the knowledge on how microstructural variation influences the deformation, fracture and wear behavior of ZrN based nanostructured coatings. READ MORE
