Hard Rock Drilling: Powerful Nano Coatings
Material innovation strongly supports granite and basalt drilling breakthroughs.
Nano coatings lead this progress: they form ultra-hard, wear-resistant protective film on bit surfaces.
In granite, nano coatings reduce friction and heat, extending bit life by 20-30%.
Tips for hard rock bit materials:
- Use nano coatings on basalt bits. Enhance impact spalling resistance effectively.
- Opt for high-performance carbides. Fine-grain alloys boost hardness and toughness.
- Apply advanced materials to roller bits. Improve anti-chipping in basalt formations.
Nano coatings and alloy innovations make bits more competitive in hard rock drilling.
