1. 1. Electrochemical behavior of conducting polymers

   University essay from KTH/Kemi

   Author : Raghda Kalifa; [2022]
   Keywords : Cathodic protection; conducting polymers; conductivity; structure; compression; Katodiskt skydd; ledande polymerer; konduktivitet; struktur; kompression;

   Abstract : Ett stort industriellt problem när det gäller metalliska material är korrosion. En metod för att förhindra korrosion är genom en elektrokemisk process som kallas katodiskt skydd vilket kan utföras på två olika sätt: Katodiskt korrosionsskydd med påtryckt ström (ICCP) eller offeranod (SACP).

3. 2. Surface Engineering of Bipolar Plates for PEM-Water Electrolysis : Cost-Effective Corrosion Protection

   University essay from Linköpings universitet/Tunnfilmsfysik

   Author : Tristan Dettke; [2021]
   Keywords : Hydrogen; Water Electrolysis; Fuel Cells; Bipolar Plates; Thin Films; Coatings; Impact Coatings; IFM; Tristan Dettke; PEM;

   Abstract : Hydrogen production by PEM-Water electrolysis is an environmentally benign and promising approach to store excess energy from renewable energy sources but facing drawbacks of high costs, mainly due to a harsh cell-environment. The aim of my Master Thesis was to reduce the costs of the most expensive cell component, the bipolar plate by surface engineering. READ MORE

4. 3. Multivariate Data Analysis on (Ti,Al)N Arc-PVD coating process : MVDA of the growth parameters thickness, stress,composition, and cutting performance

   University essay from Uppsala universitet/Oorganisk kemi

   Author : Per-Olof Öqvist; [2021]
   Keywords : chemistry; material; coating; statistics; PLS; PCA; kemi; material; beläggning; statistik; PLS; PCA;

   Abstract : This diploma work was done at Seco Tools AB (SECO) in Fagersta and aimed to evaluate the possibility to model the relationship between deposition data, deposition properties and, cutting performance of a (Ti,Al)N coating on cutting inserts by applying the Multivariate Data Analysis (MVDA) modeling technique Partial Least Squares Projection to Latent Structures Modeling (PLS). Cathodic Arc Deposition (Arc-PVD) was the PVD technique focused on this study. READ MORE

5. 4. Offshore Wind Power Foundations' Corrosion Protection Strategy : Anlysis remotely controlled corrosion protection system and comparison to traditional corrosion protection of offshore wind foundation

   University essay from Linnéuniversitetet/Sjöfartshögskolan (SJÖ)

   Author : Mazen Alhamalawi; [2021]
   Keywords : natural potential; corrosion; corrosion protection system; GACP; ICCP and sacrificial anodes; naturlig potential; korrosion; korrosionsskyddssystem; GACP; ICCP och offeranoder;

   Abstract : När en metall är omgärdad av en elektrolyt, så som havsvatten, kommer det att byggas upp en naturlig potential. Det sker en elektronvandring mellan materialet och havsvattnet och ju större potentialskillnad desto större sannolikhet att metallen kommer korrodera. READ MORE

6. 5. Influence of hydrogen on mechanical properties, microstructure and fracture surface of stainless steel 316L and stainless steel 304

   University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

   Author : Mustafa Adnan Tawfeeq Salman; [2020]
   Keywords : Hydrogen embrittlement; stainless steel; microstructure; hydrogen charging; slow and fast strain rate.; Väteförsprödning; rostfritt stål; mikrostruktur; väte laddning; långsam och snabb töjnings hastighet;

   Abstract : Since hydrogen is an alternative energy source and has both economic and environmental benefits, it has received more attention. To use hydrogen a certain condition must be met, safe pressurized containers which are often made of metal. The metal isrequired due to the high mechanical strength and reasonable cost. READ MORE
