High-Vacuum Thin-Film Ceramics
Physical Vapor Deposition utilizes specialized reactive gases to engineer tailored ceramic properties:
- TiCN (Charcoal Grey): Hardness 3000 HV, friction $\mu = 0.20$, superior wear resistance against nickel-silver keys.
- TiAlN (Dark Bronze): Hardness 3300 HV, oxidation threshold up to $800^\circ\text{C}$, ideal for fire doors.
