Dental Coatings - PVD Coating

Technology

For generation of the TiN coating, the energy transfer of the arc into the target releases titanium atoms, ionises them and accelerates them through the applied voltage towards the implant. During the process, nitrogen is introduced into the vacuum chamber and the nitrogen atoms combine with the titanium atoms on the implant surface to form the desired titanium nitride coating.

Properties

• Color: golden yellow
• Coating thickness: 0.5–7 µm
• Roughness Ra: ≤ 0.05 µm
• Adhesion strength: class 0 and 1
• Coating hardness: ~ 2,300 HV

Range of Application

• Instruments for dental use

Advantages of the Procedure

• Biocompatible
• Extended life time due to reduced wear

Technology

For generation of the ZrN coating, the energy transfer of the arc into the target releases zirconium atoms, ionises them and accelerates them through the applied voltage towards the implant. During the process, nitrogen is introduced into the vacuum chamber. The nitrogen atoms combine with the zirconium atoms on the implant surface to form the desired ZrN coating.

Properties

• Color: pastell yellow
• Coating thickness: 0.5–6 µm
• Roughness Ra: ≤ 0.05 µm
• Adhesion strength: class 0 and 1
• Coating hardness: ~2,500 HV

Range of Application

• Instruments for dental use

Advantages of the Procedure

• Biocompatible
• Extended life time due to reduced wear

Technology

DLC coatings are metal-containing, amorphous carbon coatings consisting of the elements chromium and carbon. Through a PVD process both elements are converted into the requested DLC hard layer.

Properties

• Color: black
• Coating thickness: 0.5–2.5 µm
• Roughness Ra: ≤ 0.05 µm
• Adhesion strength: HF 1–3
• Hardness: ~700 HV
• Low friction coefficient

Range of Application

• Instruments for dental use

• Biocompatible
• Extended life time due to reduced wear
