1. 1. High Temperature Tribology in Hot Stamping

   Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Författare :Evan Kurnia; [2019]
   Nyckelord :high temperature tribology; hot stamping; acoustic emission; condition monitoring; hardfacing;

   Sammanfattning : Many automotive components are made of Al-Si coated ultra-high strength boron steel (UHSS) and are produced by hot stamping process. In this process, the workpiece is heated to an austenitizing temperature and is then formed and quenched simultaneously between the tools to achieve the desired shape and high strength. LÄS MER

3. 2. Self-Lubricating Properties of Laser Claddings for High Temperature Forming Processes

   Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Författare :Tugce Caykara; [2018]
   Nyckelord :self-lubricating; steel; aluminium; friction; wear; high temperature; hot forming;

   Sammanfattning : This thesis summarizes the work done on tribological characterization of multifunctional hardfacing coatings with self-lubricating properties, intended for use in mechanical components operating in high temperature applications for which conventional lubricants are no longer effective. Deposition techniques like laser cladding have a great potential in reworking/repair of high value industrial components in order to extend their lifetime. LÄS MER
