In early 2026, tungsten carbide cutting blades coated with a multi-layer AlCrSiN film successfully completed validation at a shipbuilding facility.
After 2,000 hours of exposure in a 5% NaCl salt spray environment per ISO 9227 standards, the cutting edges showed no pitting corrosion and achieved a service life of 120,000 meters when slitting glass fiber-reinforced epoxy panels—far surpassing conventional cemented carbide tools, which typically fail within just 72 hours under the same conditions.
