Government scientists develop plasma coating technologies

The first is a wear-resistant and anti-corrosion coating for screw rods, which are a key tool in the plastic injection formation manufacturing industry. Screw rods are used to press molding plastics mixed with chemicals, and are therefore easily worn out. The new plasma coating technology covers the rods with a very dense and sticky film that enhances the life-span of a typical screw rod by three times.

Scientists at INER, which is a part of the Atomic Energy Council, have also developed a new coating for screw bolts and nuts used by the aerospace industry. Currently, the aerospace industry coats those parts with a cadmium metal layer using electroplating, but that is environmentally unfriendly because cadmium is a toxic heavy metal. The new coating instead uses aluminum that is vaporized using plasma technology.

Until now, Taiwanese manufacturers of touch-screen panels have had to import most of the key materials used to make the flexible, transparent thin film that makes up the touch panel. INER, however, has recently developed homegrown technology to make those films, which could help reduce production costs significantly.

These three new technologies add to a portfolio of about 20 plasma technologies developed by the INER. “We will continue to develop more innovative and practical integral solutions for industry,” the institute said in a statement.
