  2. 2. Atmospheric corrosion of zinc-aluminum and copper-based alloys in chloride-rich environments Microstructure, corrosion initiation, patina evolution and metal release

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Xian Zhang; KTH.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; atmospheric corrosion; chloride deposition; Zn-Al alloy coatings on steel microstructure; Cu sheet and Cu alloys; microstructure; corrosion initiation; corrosion product evolution; metal release; SEM; IRAS; CRM.; Kemi; Chemistry;

    Abstract : Fundamental understanding of atmospheric corrosion mechanisms requires an in-depth understanding on the dynamic interaction between corrosive constituents and metal/alloy surfaces. This doctoral study comprises field and laboratory investigations that assess atmospheric corrosion and metal release processes for two different groups of alloys exposed in chloride-rich environments.

  3. 3. High resolution electrical characterization of III-V materials and devices

    University dissertation from Kista : Mikroelektronik och informationsteknik

    Author : Olivier Douheret; KTH.; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; condensed matter; electrics; electrical; materials science; Elektroteknik; elektronik och fotonik; TECHNOLOGY Electrical engineering; electronics and photonics; TEKNIKVETENSKAP Elektroteknik; elektronik och fotonik;

    Abstract : The continuing shrinkage of semiconductor devices towards nanoscale features and increased functionality has prompted a strong need for high-resolution characterization tools capable of mapping the electrical properties with nanoscale lateral resolution. In this regard, scanning capacitance microscopy (SCM) scanning spreading resistance microscopy (SSRM) and Kelvin probe force microscopy (KPFM) have emerged as powerful techniques. READ MORE

  4. 4. Use of local electrochemical techniques for corrosion studies of stainless steels

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Nuria Fuertes; KTH.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stainless steel; passive film; thermal oxides; work function; pickling; SKPFM; SVET; XPS; AES; Materials Science and Engineering; Teknisk materialvetenskap;

    Abstract : The excellent corrosion resistance of stainless steels arises from the presence of a passive film on its surface. Above 10.5wt% Cr a chromium oxide of 1-3 nm is formed on the surface of the metal that in case of damage will reform and hinder further dissolution of the metal. READ MORE

  5. 5. An Experimental Study to Understand the Localized Corrosion and Environment-Assisted Cracking Behavior of AISI 420-Martensitic Stainless Steel

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Krishnan Hariramabadran Anantha; KTH.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemi; Chemistry;

    Abstract : Motivation and aim: Currently steel molds are designed with cooling channels to reduce the solidification time of molten plastic within the mold to improve the productivity. As water is generally used as the cooling medium, corrosion and environment-assisted cracking (EAC) leading towards the dysfunction of mold, can increase the production downtime. READ MORE
