GSX II coating
- Achieves excellent heat resistance with enhanced oxidation resistance and heat dissipation
- Features a new layered structure for high hardness
- Optimizes the crystal structure of the film for increased resistance to wear and adhesion
Heat resistance far superior to competitors
Oxidation resistance evaluation (calo test crater after being held for 1 hour in the atmosphere at 1,100°C)

Oxidation resistance tests conducted under NACHI standards showed GSX II coating limits oxidation to 0.3µm from the surface, whereas coating products of competitors resulted in
total oxidation of the coating layer.
