Smooth Surface
High smoothness, droplet-free surface, extremely low friction coefficient, and nearly defect-free surface quality.
Strong Wear Resistance
Combines high hardness, high density, and strong coating-substrate adhesion, with outstanding wear resistance, significantly improving the service life of cutting tools and molds.
Low-Stress Coating
Low stress; while providing high wear resistance, the coating has extremely high toughness, maintaining cutting edge integrity without coating cracking or peeling.
Flexible Ionization Control
Adjustable ionization rate, allowing flexible matching of coating performance. The process is flexible, and the coating can be either thick or thin.
