Ionbond™ CVD 29 Al2O3

Aluminum oxide coating for high temperature forming applications

Ionbond^™ CVD 29 Al₂O₃ is a multi-layered CVD coating engineered to be able to cope with the aggressive conditions present in high temperature forming applications. Ionbond^™ CVD 29 Al₂O₃ exhibits excellent thermal stability, chemical inertness, and high wear resistance, which makes it the leading solution for hot extrusion applications for both ferrous and non-ferrous alloys.
Additionally, the thermal stability, density, and corrosion resistance of Ionbond^™ CVD 29 makes it an ideal solution for open tolerance tools used in aluminum casting applications where sticking of aluminum is the primary cause of downtime.

Ionbond^™ CVD 29 is deposited at 1000 °C. Therefore it is only recommended for tool materials compatible with the CVD process. Dimensional change will occur on tool steel materials coated with Ionbond^™ CVD 29, so sufficient dimensional tolerances are required to accommodate the expected dimensional change.
