  2. 1. Cold lap formation in Gas Metal Arc Welding of steel : An experimental study of micro-lack of fusion defects

    Author : Peigang Li; Lars-Erik Svensson; Norbert Enzinger; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tandem GMAW; old laps; lack of fusion; Spatter; Overlap; Overflow; Manganese; Silicon; Oxides; Temperature; Manufacturing and materials engineering; Produktions- och materialteknik;

    Abstract : Cold laps are defined as micro-lack of fusion defects at the weld toe more or less parallel to the surface of the parent plate. These defects are known to negatively influence the fatigue properties of weldments. Previous studies suggest that cold lap formation can not be avoided completely in Gas Metal Arc Welding (GMAW).

  4. 2. On the bone response to oxidized titanium implants. The role of microporous structure and chemical composition of the surface oxide in enhanced osseointegration

    Author : Young-Taeg Sul; Göteborgs universitet; []
    Keywords : Oxidized titanium implants; micro arc oxidation; oxide growth; surface oxide properties; bone; biomechanical tests; histomorphometry; enzyme histochemistry.;

    Abstract : Background: Titanium implants have been widely used clinically for various types of bone-anchored reconstructions. A thin native oxide film, naturally formed on titanium implants contacts with bone tissue and has been considered to be of great importance for successful osseointegration. READ MORE

  5. 3. On the Bone Tissue Response to Surface Chemistry Modifications of Titanium Implants

    Author : Byung-Soo Kang; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Osseointegrated titanium implants; Magnesium and Calcium Incorporated Bioactive Titanium Oxide; Metal Plasma Immersion Ion Implantation and Deposition; Micro Arc Oxidation; Clinical Implants; In Vivo Bone Response;

    Abstract : Background: Surface properties of titanium implants play an important role in osseointegration. From 1990, a lot of engineering techniques have been applied to dental implant productions for improving their clinical performance by changing surface properties. READ MORE
