1. 1. Barrier properties of model coatings using recycled iron oxide pigment

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Nathalie Hagenfjärd; [2021]
   Keywords : Organic coatings; Iron oxide pigment; EIS; Barrier properties;

   Abstract : The aim of this study was to compare the barrier properties of organic coatings with the same polymer matrix but different types of iron oxide particles, commercial and recycled. The work was carried out for the company SSAB with the aim of investigating whether the pigment Merox ferric oxide, which is produced in-house at the company during the pickling process, can be used and replace commercial iron oxide pigment.

3. 2. Acid retardation : recovery and recycling of acid and metal

   University essay from Luleå tekniska universitet/Industriell miljö- och processteknik

   Author : Cecilia Bood; [2020]
   Keywords : Acid retardation; Ion exchange; Pickling; Stainless steel;

   Abstract : During the production of steel, an oxide scale is formed on the surface and to achieve anadequate quality of the surface the scale needs to be removed. Acid pickling is a surfacetreatment where the oxide scale is removed by acid. READ MORE

4. 3. Neutralization of acidic wastewaters with the use of landfilled Electric Arc Furnace (EAF) high-alloyed stainless-steel slag : An upscale trial of the NEUTRALSYRA project

   University essay from KTH/Materialvetenskap

   Author : Rahul Puthucode; [2019]
   Keywords : Landfilled High-alloyed Electric Arc Furnace EAF slag; Slag neutralization potential; Slag recycling;

   Abstract : The landfilling of slag obtained from the high alloyed Electric Arc Furnace (EAF) steel making process, constitutes an environmental treat for society as well as an economical problem for the companies producing it, due to the costs related to waste management practices. Conventional methods of slag recycling are abundantly used among the steelmaking business, but due to their particular physical properties, high- alloyed EAF slags cannot be properly valorized.

5. 4. Pitting Corrosion Evaluation of Post-Weld Cleaning Methods for Stainless Steel Welds

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Jimmy Holgersson; Klara Trydell; [2019]
   Keywords : ;

   Abstract : Welding stainless steel creates an oxide film, heat tint, on the surface and around the joint. It disrupts passivation and influence the corrosion resistance for the material. The result is often a decrease in pitting corrosion resistance for the joint and surrounding area. The heat tint is therefore commonly removed by post weld cleaning. READ MORE
