Adhesion is Physics, Not Luck.
Synchronizing the Coefficient of Thermal Expansion (CTE) to eliminate shear stress at the oxide interface.
Porcelain Delamination & Late Fracture
Risk Addressed
Porcelain Delamination & Late Fracture
The primary cause of ceramic failure is thermal mismatch. If the metal contracts faster than the ceramic during cooling (High CTE), the ceramic is placed under compression. If it contracts slower (Low CTE), the ceramic cracks under tension. ValidTi alloys are engineered to lock into the 'Safe Compression Zone' of leading low-fusing ceramics.
