2. 1. Surface Integrity Characterization of Gears with respect to Running-in

   Author : Dinesh Mallipeddi; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; micropitting; surface asperities; running-in; surface roughness; residual stresses; Gears; surface chemistry;

   Abstract : A gearbox with gears of different sizes is part of a vehicle transmission system that plays an important part in transmitting the engine power to the wheels. The efficient energy transmission highly relies on the performance of gears. Together, the mesh efficiency and durability determines the gear performance. READ MORE

4. 2. Surface integrity on post processed alloy 718 after nonconventional machining

   Author : Jonas Holmberg; Tomas Beno; Anders Wretland; Johan Berglund; Mikael Olsson; RISE; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alloy 718; Non-conventional machining; post processing; surface integrity; Microstructure; Residual stress; Electron back scattering diffraction; Material removal rate; Manufacturing; Surface and Joining Technology; Bearbetnings-; yt- och fogningsteknik; Production Technology; Manufacturing and materials engineering;

   Abstract : There is a strong industrial driving force to find alternative production technologies in order to make the production of aero engine components of superalloys even more efficient than it is today. Introducing new and nonconventional machining technologies allows taking a giant leap to increase the material removal rate and thereby drastically increase the productivity. READ MORE

5. 3. Machinability of Single-phase Materials : Surface integrity and tool wear analysis

   Author : Mike Olsson; Industriell Produktion; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machinability; Niobium; Tungsten; Oxygen-free copper; Surface integrity; Tool wear;

   Abstract : The quality and performance of products are particularly important in sectors such as research facilities and in the nuclear, military and space industries. These sectors make use of high-performance materials that are uncommon in other contexts and therefore place high requirements on personnel, machines and tools. READ MORE

   Abstract : A gearbox with gears of different sizes is part of a vehicle transmission system and plays an important part in transmitting the engine power to the wheels. The efficient energy transmission highly relies on the performance of gears. Together, the mesh efficiency and durability determines the performance of gears. READ MORE

7. 5. Surface integrity and corrosion behavior of stainless steels after grinding operations

   Author : Nian Zhou; Rachell Pettersson; Ru Lin Peng; Stuart Lyon; Högskolan Dalarna; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stainless steel; stress corrosion cracking; surface integrity; grinding; residual stress; Steel Forming and Surface Engineering; Stålformning och ytteknik;

   Abstract : Stainless steels are widely used in applications where both the mechanical properties of steels and high corrosion resistance are required. There is continuous research to enable stainless steel components to be produced in a more economical way and be used in more harsh environments. READ MORE
