Nitron O

Titanium alloys Hhave very attractive strength-to-weight ratios, good fatigue strength and outstanding corrosion properties. However, these alloys have rather poor tribological characteristics resulting in problems with wear.

In lightly loaded applications The performance can be greatly improved by coating with PVD Titanium Nitride (TiN), but in the case of higher loads, a process which can improve the load bearing capacity of the material is required.

Tecvac has developed the Nitron process To solve this problem. The components are treated using a duplex process in which a nitrided diffusion zone is produced beneath a PVD hard coating.

This patented technology results in coatings which are highly adhered and supported by a hardened subsurface layer.

Applications

• Aerospace and Sub-sea
• Motorsport
• Chemical Plant and FoodProcessing
• Load Bearing Ti Components

Nitron processing is carried out under vacuum At 700°C. At this temperature there is minimal detrimental effect to fatigue properties but bonding of the coating layer to the diffused zone is greatly enhanced.

Applications for Nitron are in areas where titanium alloys are preferred but high loading wear conditions exist.
