2. 16. Functional Performance of Gadolinium Zirconate/Yttria Stabilized Zirconia Multi-Layered Thermal Barrier Coatings

   Author : Satyapal Mahade; Per Nylén; Nicolaie Markocsan; Ping Xiao; Högskolan Väst; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Composite; Erosion; Gadolinium Zirconate; Suspension Plasma Spray; Thermal Barrier Coatings; Thermal Cyclic Test; Thermal Conductivity; Yttria Stabilized Zirconia.; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

   Abstract : Yttria stabilized zirconia (YSZ) is the state-of-the-art ceramic top coat material used for thermal barrier coating (TBC) applications. Demand for higher efficiency in gas turbine engines has led to a continuous increase in the gas in let temperature. However, this increase in temperature has pushed YSZ to its upper limit. READ MORE

4. 17. Enhanced heat transfer and tool wear in high-pressure coolant assisted turning of alloy 718

   Author : Nageswaran Tamil Alagan; Tomas Beno; Uta Klement; Anders Wretland; Mikael Olsson; Högskolan Väst; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alloy 718; Cavitation; Coolant-boiling; High-pressure coolant; Heat dissipation; Leidenfrost effect; Textured insert; Tungsten carbide; Tool life; Tool wear; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

   Abstract : Heat generated in a machining process is a common and critical obstacle faced in today's manufacturing industries. The heat generated in the cutting zone has adirect negative influence on the tool life, which, in turn contributes to increasing the manufacturing costs. READ MORE

5. 18. Inductive measurement of narrow gaps for high precision welding of square butt joints

   Author : Edvard Svenman; Anna-Karin Christiansson; Högskolan Väst; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Eddy current; Seam tracking; Measurement; Laser beam welding; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

   Abstract : A recent method in aero engine production is to fabricate components from smaller pieces, rather than machining them from large castings. This has made laser beam welding popular, offering high precision with low heat input and distortion, but also high productivity. READ MORE

6. 19. Towards radical improvement in production systems

   Author : Daniel Gåsvaer; Christer Johansson; Jens von Axelson; Mats Winroth; Mälardalens högskola; []
   Keywords : Improvement; Radical; Innovation; Kaikaku; Innovation and Design; innovation och design;

   Abstract : As the speed of change is increasing, it’s of great importance that manufacturing companies strive to achieve not only incremental improvements, but also radical improvements within their production systems. Thus, more research has to be focused on how to realize radical improvement. READ MORE

7. 20. Towards understanding the fatigue behaviour of Alloy 718 manufactured by Powder Bed Fusion processes

   Author : Arun Ramanathan Balachandramurthi; Per Nylén; Robert Pederson; Johan Moverare; Filippo Berto; Högskolan Väst; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fatigue; Additive Manufacturing; Powder Bed Fusion; Superalloy; Microstructure; Surface Roughness; Production Technology; Produktionsteknik;

   Abstract : Additive Manufacturing (AM) is a disruptive modern manufacturing process in which parts are manufactured in a layer-wise fashion. Among the metal AM processes, Powder Bed Fusion (PBF) technology — comprised of Electron Beam Powder Bed Fusion (EB-PBF) and Laser Beam Powder Bed Fusion (LB-PBF) —has opened up a design space that was formerly unavailable with conventionalmanufacturing processes.
