The Twelfth International Symposium on thermal spraying and the Thirteenth National Annual Meeting of thermal spraying
Abstract
According to the market survey by research organizations, the total market size of thermal spray industry
in Japan is approximately 100 billion yen. This market consists of three sectors, turnover of coating job
shops (45 billion yen), in-house production of big comp anies (45 billion yen), and sales of thermal spray
equipment and consumables by suppliers (10 billion yen). In this paper, the current segmentation of
application fields and main practical applications in the coating service market by coating job shops are
introduced. And the future trend of the market is also discussed.
Introduction
Thermal spray in Japan has a long history, beginning with Mr. Kenjiro Ezawa, a merchant of precious
metals in Ginza, Tokyo. He was interested in the thermal spray devices which was exhibited in the World
Exposition held in Paris. Then, he purchased thermal spray devices and the patent in 1919 from Dr. Schoop,
the inventor of thermal spray technology, and brought them to Japan for the first time.
Major applications of the thermal spray devices at the time were art works coated with zinc and bronze,
and decoration of buildings. Then, Mr. Ezawa developed arc gun, for which patent was obtained, and
promoted industrial applications of anti-corrosion coating for steel structures. He named the technology
"Metallicon"by combining English and Latin, licensed patents, and increased licensee firms for Metallicon.
In 1947, he set up Japan Metallicon Service Contractors Association with 12 Metallicon firms, aiming at
the new development of thermal spray application. In 1957, Japan Thermal Spray Association (currently,
JTSS) was established to expand the new western hardfacing technology in Japan. Responding to such
trend, The Japan Metallicon Service Contractors Association was reorganized to Japan Thermal Sprayers
Association (JTSA) to promote the hardfacing technology in 1958.
The size of the coating service market in Japan in those days was about 1 billion yen and there were no
applications other than anti-corrosion thermal spray. However, the application fields had expanded into
other fields, and the market size reached to 45 billion yen in 2006, and about 50 billion yen in 2008. It had
grown 50 times in 50 years overcoming the repeated recessions.
This paper describes the development and future prospect of the coating service market focusing on 3
viewpoints.
1.In-house production by big companies and coating service market by job shops
2.Self-development and joint-development of new applications
- Application development in steel industry
- On-site job and others
3.Future prospect of thermal spray coating applications and coating service market
