   Abstract :    With the advancement and accessibility of local probing techniques that can operate at the submicron scale it has become possible to analyse the local corrosion properties of industrially important metallic materials and relate these properties to microstructure characteristics of the same materials. In this doctoral study the focus has been on copper-zinc samples, both as industrial brass alloys and as micro-patterned copper-zinc samples. READ MORE

5. 3. Application of copper corrosion inhibitors in mineral oil : Surface analytical studies and corrosion mitigation evaluations

   Author : Martina Levin; Christofer Leygraf; Per Redelius; Roy Johnsen; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : This doctoral thesis explores the copper corrosion inhibiting properties of a number of nitrogen containing hetero-organic compounds in refined mineral oil. Traditional organic corrosion inhibitors, as well as novel and bioorganic compounds have been studied. READ MORE
