HYBRID CERMET Uncoated CERMET MEGACOAT NANO CERMET TN610/TN620 PV710/PV720 3 Hybrid Technology Attributes Maintain Superior Surface Finish and Machining Stability Excellent Surface Finish Combining the conventional cermet bonded phase (nickel, cobalt) and the special high melting point metallic bonded phase. Provides high adhesion resistance to eliminate galling of the work piece. Surface Finish Comparison (In-house Evaluation) Specialized Strengthening Technology High Melting Point “Hybrid Bonded Phase” 01.929"- 00 Highspeed Low Speed Surface Finish Surface Roughness (00.158" 00.591") i (Vc = 50 180 sfm) Good noa i 1S8 77 .197 .2 Excellent Fracture Resistance Improved strength with uniform micro grain hard phase and superior compressive stress with high melting point bonded phase. This combination yields greater fracture resistance. Specialized Strengthening Technology “Hybrid Hard Phase” Compressive Residual Stress in Hard Phase Internal Evaluation) TN620 Grain Structure Inner Structure TN620 Conventional Micro Grain Cermet R Specialized Strengthening Technology Special Surface-Hardened “Hybrid Structure” Excellent Wear Resistance Excellent fracture resistance with surface-hardened layer using gradient composition technology. Continuously-varied hardness provides the combination of wear and fracture resistance. TN620’s inner structure has high toughness and chipping resistance along with greater thermal and wear resistance than that of the conventional micro grain cermet.
