  1. 1. Characterization and development of FeCrW high speed steel coating for abrasive and impact wear applications

    University essay from Chalmers tekniska högskola/Institutionen för industri- och materialvetenskap

    Author : Dennis Rinkel; [2016]
    Keywords : High speed steel; laser cladding; surface coating; alloy characterization;

    Abstract : XH-7 is a high speed steel alloy developed for use in surface coating to improve the impact and abrasive wear resistance of machine parts and tools. The desired structure of the material is a martensitic matrix with fine carbide and boride precipitates. READ MORE

  2. 2. Effect of Nitridation on High Temperature Corrosion of Ferritic Stainless Steel

    University essay from Chalmers tekniska högskola/Institutionen för material- och tillverkningsteknik

    Author : Tiziano Bergamo; [2013]
    Keywords : Selective Catalytic Reduction; Ferritic Stainless Steel; Plasma Nitriding; Expanded Phase; High Temperature Oxidation; Water Vapor;

    Abstract : The emission of nitrogen monoxide in the atmosphere is one of the main causes of air pollution. In this regards, the truck industry introduced the Selective Catalytic Reduction (SCR) in exhaust after-treatment system of heavy-duty trucks. Through the use of urea water solution injected into the gas flow, NOx can be reduced to N2 and H2O. READ MORE

  3. 3. Influence of microstructure and proteins on the metal release of micron-sized stainless steel powder particles

    University essay from KTH/Materialvetenskap

    Author : Neda Mazinanian; [2012]
    Keywords : stainless steel particles; metal release; proteins; microstructure; surface characterization;

    Abstract : Knowledge on metal release processes from stainless steel powder, which can be potentially inhaled at occupational settings, is essential within the framework of human health and environmental risk assessments. An in-depth knowledge concerning powder history, physical properties of particles (e.g. READ MORE

  4. 4. Hydrogen-assisted stress corrosion cracking of high strength steel

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Rohollah Ghasemi; [2011]
    Keywords : Hydrogen embrittlement; hydrogen induced cracking; stress corrosion cracking; high strength steel; uniform corrosion; SSRT; hydrogen charging; fractography; hydrogen degradation;

    Abstract : In this work, Slow Strain Rate Test (SSRT) testing, Light Optical Microscopy (LOM) and Scanning Electron Microscopy (SEM) were used to study the effect of micro-structure, corrosive environments and cathodic polarisation on stress corrosion cracking (SCC) of two grades of high strength steels, Type A and Type B. Type A is manufactured by quench and tempered (Q&T) method. READ MORE
