What is Nano-Film Coating?
A colorless and transparent ceramic nano-film with a heat resistance of 500 °C and up
Yamaha’s SixONy nano-film coating has been adapted for use in mass production on motorcycle exhaust pipes for the first time in the world. Sputtering deposition (a type of Physical Vapor Deposition, or PVD) provides superior levels of heat resistance, gas barrier effectiveness and insulation performance, despite the ceramic SiON (silicon oxynitride) film on the base material being only 20–80 nm thick. Expectations are high for its possible applications across a wide range of industries. The film can be produced either in a transparent form or colored form, so it can be used as a decorative coating in addition to being a protective heat-resistant coating.
*Based on Yamaha Motor research.
- Heat resistant up to 700 ℃ (no oxidation after 24-hour exposure at 500 ℃)
- Resistant against saltwater and acids
- Excellent gas barrier effectiveness
- Improves the hardness of the base material
- Highly heat-resistant, colorless and transparent film (can be altered for color variations)
- Costs less than decorative plating
- Well-suited to manufacturing with a coating temperature of 50 ℃ or lower
This paper in the Yamaha Motor Technical Review publication introducing our ongoing R&D efforts describes how Yamaha created the SixONy nano-film coating.
This page on the “Seeds of Creation:Waza and Sube” website introducing Yamaha Motor’s technologies talks about the SixONy nano-film coating.
