Thermal spraying is used widely in many industrial sectors in the North European Countries: Finland, Sweden, Norway and Denmark. Important areas where thermal spraying is used petroleum, paper, metals, transport, defence and high-tech machinery industries. In Finland thermal spray technology has wideest use in the pulp and paper industries with several companies spraying various types of rolls and cylinders. In Sweden, thermal spray technology is of great importance in the manufacture of aero engines and in industrial gas turbine applications. In Norway thermal spraying is widely used in various offshore applications, including subsea oil drilling enterprises. Development and innovation in thermal spray technology in the Nordic countries is dominated by research conducted in Finland and Sweden, followed by Denmark and Norway. In particular, research groups from Sweden and Finland, as well as from Norway, have routinely presented their research results at international conferences and in international journals.
