A
Special Surface Treatment: Chipping resistance and adhesion resistance are significantly improved by special surface treatments applied to suit the application High Strength Alumina Layer: Significantly improves the coating strength by controlling crystal growth direction High Hardness Micro-Grain TiCN Layer: Significantly improves the coating hardness by using a fine and uniform crystal structure High Adhesion Technology: Significantly improves adhesion strength through a smooth interface between the coating and carbide substrate
Our proprietary super multi-layered coating structure: Advanced nanotechnology enables nanometre-level thickness (1 nanometre is one billionth of a metre) Hardness, thermal resistance and toughness are significantly improved by alternately layering one thousand layers of super thin films
