dropless® 5000 Plus is a ta-C DLC coating, deposited with dropless® technology patented by Argor-Aljba, at a temperature below 100 °C with a standard thickness of 1 µm. The coating dropless® 5000 Plus has a very high sp3 percentage (typical of natural diamond) of about 85% and a hardness of about 48 GPa (5000 HV). It has a dark-grey color.

All provided data are approximate values, depend on the application, environment and test conditions. Coating hardness HIT [GPa] measured by nano indentation according to ISO 14577. Hardness can be adapted to the application. Friction coefficient (dry) compared to the steel determined by ball-on-disc dry test with a steel sphere according to ASTM G99. During the running-in the indicated values may be exceeded. Maximum service temperature [° C] These are approximate values.
High hardness of the coating, protection against adhesive wear and friction.
High thermal stability up to 500 ° C: possibility of MQL and dry processing.
Thanks to the dropless® deposition technology, the surface roughness is not altered and, in particular conditions, contributes to its reduction. dropless® 5000 Plus offers a wide application field:
- cutting tools for turning, milling, drilling, countersinking, boring of non-ferrous materials
- particularly suitable for both hard metal and ceramic micro-tools
- molds
- components of the watchmaking sector
