SLIDING AND HARD COATING
Indispensable for quality
High-Performance Coatings
from LUTZ BLADES
The foundation must be right – this is, of course, a prerequisite for LUTZ blades. That is why every material we use is optimally matched to the task it needs to perform. This also applies to our sliding and hard coatings. Our experts will recommend the most suitable coating for your specific cutting application, environment, and production process.
HOW YOU BENEFIT
Thanks to our high-performance coatings
- Higher cutting speeds and increased output
- Longer service life and fewer blade changes
- Reduced friction between the cutting edge and the material
- Superior cutting quality
COATING TYPES
As part of our coating program
- TiN (Titanium Nitride)
- TiC (Titanium Carbide)
- TiCN (Titanium Carbonitride)
- TiAlN (Titanium Aluminium Nitride)
- DLC (Diamond-like Carbon)
- PTFE (Poly-Tetra-Fluoro-Ethylene) – Teflon®
Coating
How it works
Friction occurs between the blade and the material being cut. This friction leads to small but unavoidable damage to the cutting edge. Over time, these micro-damages accumulate and cause the cutting edge to become dull.
Solution ASelecting a material quality that slows down the formation of damage.
Solution BChoosing a coating that acts as a thin film between the cutting edge and the material being cut.
You can see the performance advantages of a coated blade compared to an uncoated blade in the chart.
DIFFERENT COATING TYPES
Variants within our coating program
A standard golden-colored coating with high wear resistance and a friction coefficient of 0.4–0.7, applicable up to 300 °C.
Features lower wear resistance compared to TiN and a friction coefficient of 0.3–0.5; typically anthracite in color.
An intermediate coating positioned between TiN and TiC; anthracite-colored depending on the carbon and nitrogen ratio.
Provides higher oxidation resistance than TiN with a similar friction coefficient; usually blue-anthracite in color.
Features a very low friction coefficient (approx. 0.1) and high impact/thermal resistance (between 100–300 °C).
Offers extremely low friction and resistance to acids/alkalis; particularly suitable for medical applications, resistant up to 250 °C.
A varnish applied to the entire surface to distinguish between different material thicknesses and provide corrosion protection.
Darkens the surface to provide light corrosion protection and serves as a visual identifier.
