  2. 1. Workpiece steels protecting cutting tools from wear : A study of the effects of alloying elements on material transfer and coating damage mechanisms

    Author : Toshiharu Aiso; Staffan Jacobson; Urban Wiklund; Staffan Söderberg; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metal cutting; Steel; Cutting tools; Transfer; Coating; Sliding; Teknisk fysik med inriktning mot tribomaterial; Engineering Science with specialization in Tribo Materials;

    Abstract : The vision of this thesis is to improve the machinability of workpiece steels. Workpiece material frequently transfers to the cutting tools during machining, and the transfer layers then forming on the tools may give both good and bad effects on machining performance and tool life.

  5. 3. Tribology at the Cutting Edge : A Study of Material Transfer and Damage Mechanisms in Metal Cutting

    Author : Julia Lundberg Gerth; Urban Wiklund; Uppsala universitet; []
    Keywords : Tribology; Metal cutting; Gear hobbing; Wear; Coating; Residual stress; Material transfer; Steel; Teknisk fysik med inriktning mot tribomaterial; Engineering Science with specialization in Tribo Materials;

    Abstract : The vision of this thesis is to improve the metal cutting process, with emphasis on the cutting tool, to enable stable and economical industrial production while using expensive tools such as hobs. The aim is to increase the tribological understanding of the mechanisms operating at a cutting edge and of how these can be controlled using different tool parameters. READ MORE

    Keywords : Hydroxyacrylate-melamine copolymer; cellulose nanocrystals CNC ; cellulose nanofibrils CNF ; Electrochemical impedance spectroscopy EIS ; atomic force microscopy AFM ; corrosion protection performance; water uptake; nanomechanical and nano-wear properties; coating; nanocomposite.; Hydroxyakrylat-melamin-sampolymer; cellulosananokristaller CNC ; cellulosananofibriller CNF ; Elektrokemisk impedansspektroskopi EIS ; atomkraftsmikroskopi AFM ; korrosionsskyddsprestanda; vattenupptag; nanomekaniska egenskaper och nano-slitage; coating; nanokomposit.; Kemi; Chemistry;

    Abstract : Corrosion protection is commonly achieved by applying a thin polymer coating on metal surfaces. In this doctoral thesis, a waterborne hydroxyacrylate-melamine copolymer coating was used for this purpose. The first step was to find the optimal curing conditions. READ MORE

  7. 5. Improved titanium and steel implants : Studies on bisphosphonate, strontium and surface treatments

    Author : Paula Linderbäck; Pentti Tengvall; Per Aspenberg; Håkan Engqvist; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : Purpose: The general aim of this thesis was to increase the understanding of biomaterial surface modifications and local delivery of osteoporosis drugs for bone integration. We therefore (i) characterised and investigated model surface coatings for controlled drug delivery in a rat tibia screw model (ii) elucidated the effect of surface treatment for activation of complement system in vitro.
