1. 21. Low slope roofs : Moisture transfer in inverted roofs constantly exposed to high moisture loads and drainage systems

   Master-uppsats, KTH/Byggnadsteknik

   Författare :Charalampos Antonopoulos; [2017]
   Nyckelord :inverted roofs; green roofs; corrosion; corrosion protection; paint coatings; drainage; horizontal valleys; drains; overflows;

   Sammanfattning : Low slope roofs are roofs with an inclination between 1:16 and 1:4 and have been constructed and preferred for many years due to the benefits they present. The goal of the present work is to study the following problems of low slope roofs, as they are suggested by previous relevant theses and the current needs of the market. LÄS MER

3. 22. Defect formation in laser welded steels after use of corrosion protection coating

   Kandidat-uppsats, KTH/Materialvetenskap

   Författare :Elias Repper; Amanda Carsbring; [2017]
   Nyckelord :Laser welding; steel; porosity; mid-section bulging; defects; corrosion protection;

   Sammanfattning : This bachelor thesis was made in collaboration with Scania. The objective was to find the cause for defects found in some rear axle welds. It was known axle material was coated with anti-corrosive oil. Oils were examined through ICP-AES, and then compared to the composition found on the surface of the steel samples. LÄS MER

4. 23. Corrosion protection of powder coatings : Testing the barrier properties and adhesion of powder coating on aluminum for predicting corrosion protection by Electrochemical Impedance Spectroscopy

   Master-uppsats, Högskolan i Jönköping/JTH, Produktutveckling

   Författare :Björn Persson; johanna Svensk; [2017]
   Nyckelord :Electrochemical Impedance Spectroscopy; EIS; corrosion protection; powder coating; barrier properties; adhesion; aluminium;

   Sammanfattning : The choice of corrosion protection system depends on the environment and needed lifetime for the product. The right corrosion protection should be selected in a sustainable point of view, since a well-selected coating system can reduce the environmental and economical impact, by using less and better material.

5. 24. Pitting corrosion on stainless steel with or without passivation

   Master-uppsats, Lunds universitet/Centrum för analys och syntes

   Författare :Jeanette Karlsson; [2017]
   Nyckelord :materials chemistry; materialkemi; Chemistry;

   Sammanfattning : The stainless steel metal includes a large group of alloys and which one should choose for a process can be difficult to determine. Despite much research on corrosion, there is still disagreement on the impact of the corrosion resistance from passivation. LÄS MER

7. 25. BIM i förvaltningsfasen : En studie om möjligheter i förvaltningsfasen av en byggnad med hjälp av en väl utförd informationsmodell

   Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

   Författare :Erik Öhman; [2017]
   Nyckelord :BIM; fastighetsförvaltning;

   Sammanfattning : BIM – byggnadsinformationsmodellering eller byggnadsinformationsmodeller är begrepp som idag känns igen av de flesta i byggbranschen och många är överens om vilken stor potential som finns med att använda denna nya teknik. Trots detta går implementeringen av det här nya arbetssättet trögt i branschen. LÄS MER
