Vessels as war reparations
Finnish shipyards delivered over 500 different
vessels to the Soviet Union as war reparations. A majority of the vessels were manufactured using a new
welding method, which kept the welding technology department of VTT’s metal technical laboratory busy.
In the 1970s, especially the shipbuilding industry gained benefits from VTT’s corrosion research.
In modern materials research, new possibilities are opened by, for example, nanotechnology, which VTT has
utilised in coating manufacturing, etc. The sol-gel coatings developed by VTT improve the functional
characteristics of various surfaces, making them dirt-repellent, easy to clean, resistant to corrosion and oxidation, scratch-proof and wear-resistant.
Nanotechnical coatings have increased the functionality and efficiency of lift surfaces, combustion boilers
and filtration solutions for professional kitchens.
