  2. 1. On Surface Topography of Cylinder Liners

    Author : Zlate Dimkovski; John Westberg; Högskolan i Halmstad; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cylinder liner; Surface Roughness; Characterisation; Honing; Wear; Blechmantel; Groove Parameters; Quality Control; Flow Simulation; Surface engineering; Ytbehandlingsteknik;

    Abstract : The frictional losses, oil consumption and emissions in internal combustion engines are in great extent controlled by the cylinder liner surface topography. This emphasises the importance of: investigating the liner’s topography by objectively characterising it, investigating its effects on the tribological function to gain a better understanding and improving its manufacturing.

  4. 2. Moisture content profiles and surface phenomena during drying of wood

    Author : Anders Rosenkilde; KTH; []
    Keywords : computer tomography; diffusion; magnetic resonance; moisture measurement; moisture profiles; surface emission; wood drying;

    Abstract : Timber drying is one of the most important processes whenmanufacturing sawn timber products. The drying processinfluences deformations, surface checking, discoloration andhence, the product quality and the manufacturing costs. READ MORE

  5. 3. Investigation of Surface Formation in As-Cast and Homogenized 6xxx Aluminium Billets

    Author : Nazlin Bayat; Torbjörn Carlberg; Håkan Olin; Yanjun Li; Mittuniversitetet; []
    Keywords : DC casting; surface segregation; surface defects; intermetallic phase; phase transformation; homogenization;

    Abstract : The direct chill (DC) casting technique to produce billets for extrusion and ingots for rollingwas developed in the 1930s. The principle, which is still valid, is a two-stage cooling with a primary cooling at a mould surface followed by water spraying directly on the surface. READ MORE

  6. 4. On Surface Topography of Steel Sheet for Car Bodies

    Author : Magnus Jonasson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; paint appearance; forming; steel sheet; bearing area; 3D surface roughness; area parameters; ball filter; friction; surface topography;

    Abstract : This thesis is a contribution to the scientific area of surface topography on sheet metal surfaces. The studies are restricted to exploring the influence of the steel sheet,s surface topography on forming properties and on appearance after painting. READ MORE

  7. 5. Corrosion and Surface Studies of Stainless Steel and Chromium Carbide Thin-Films

    Author : Jonas Högström; Leif Nyholm; Kristina Edström; Patrik Schmutz; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; corrosion; electrochemistry; thin film; stainless steel; passive film; chromium carbide; carbon oxidation; surface; depth profile; XPS; SEM; EQCM; sputtering;

    Abstract : Although the passive films that form on stainless steels have been extensively studied, the concentration depth profiles are not fully understood. Their thinness makes passive films hard to study, but angle-resolved X-ray photoelectron spectroscopy (ARXPS) is a non-destructive technique that can be used to obtain depth information. READ MORE
