    • The Effect of Bake Hardening on Quenched and Partitioned AISI 420 Stainless Steel 

      Raami, Lassi; Wendler, Marco; Volkova, Olena; Peura, Pasi (04.05.2024)
      article
      Bake hardening (BH) is a static strain aging phenomenon, where the yield strength of steel increases during industrial paint baking. In this study, the effect of standard BH treatment on the mechanical properties of a ...
    • Effect of heat treatments on the wear resistance of HVAF and HVOF sprayed tool steel coatings 

      Varis, Tommi; Lagerbom, Juha; Suhonen, Tomi; Raami, Lassi; Terho, Sakari; Laurila, Jussi; Peura, Pasi; Vuoristo, Petri (15.06.2023)
      article
      Iron-based coatings are an attractive solution for many wear applications, considering sustainability requirements such as avoidance of critical raw materials and toxic substances. Cold worked tool steels are one potential, ...
    • Enhancing the cavitation erosion resistance of AISI 420-type stainless steel with quenching and partitioning 

      Raami, Lassi; Varis, Tommi; Valtonen, Kati; Wendler, Marco; Volkova, Olena; Peura, Pasi (04 / 2023)
      article
      Stainless steels are commonly used in hydraulic components where they may be sus-ceptible to cavitation erosion. In this study the cavitation erosion resistance of AISI 420-type stainless steel is examined after quenching ...
    • High-speed laser cladding of chromium carbide reinforced Ni-based coatings 

      Tuominen, Jari; Kiviö, Jouko; Balusson, Clara; Raami, Lassi; Vihinen, Jorma; Peura, Pasi (14.07.2023)
      article
      Fusion-bonded and low-diluted overlay welded coatings are frequently very thick (>1mm). High-speed laser cladding is a novel process capable of producing thin fusion-bonded and low-diluted coatings with high coverage ...
    • Työkaluteräksen lämpökäsittely 

      Raami, Lassi (2019)
      Diplomityö
      Työkaluteräkset ovat korkeahiilisiä seostettuja teräksiä, jotka soveltuvat muun muassa leikkaaviin työkaluihin. Erityisesti jauhemetallurgiset työkaluteräkset soveltuvat käytettäväksi moniin vaativiin käyttökohteisiin, ...
