Summary
Novel titanium boron nitride (TiBN) coatings exhibit a self-forming multilayer structure. The inclusion of hexagonal boron nitride (BN) significantly reduces friction compared to titanium nitride (TiN) coatings.
Area of Science:
- Materials Science
- Nanotechnology
- Tribology
Background:
- Titanium nitride (TiN) coatings are widely used due to their hardness and wear resistance.
- Developing advanced coatings with enhanced tribological properties remains a key research area.
- Multilayer structures can offer synergistic improvements in material performance.
Purpose of the Study:
- To synthesize and characterize novel multilayer TiBN coatings.
- To investigate the structural properties of the TiBN coatings.
- To evaluate the tribological performance, specifically friction, of the TiBN coatings.
Main Methods:
- Deposition of TiBN coatings on Si (100) substrates using Plasma Immersion Ion Implantation and Deposition (PIIID).
- Characterization using X-ray Diffraction (XRD), High-Resolution Transmission Electron Microscopy (HRTEM), and Energy-Dispersive Spectrometry (EDS).
- Tribological testing via a ball-on-disk test to determine friction coefficient.
Main Results:
- XRD confirmed the presence of TiN (200) and (220) diffraction peaks in the TiBN coatings.
- HRTEM revealed a self-forming multilayer structure with face-centered cubic TiN and hexagonal BN nanocrystals embedded in an amorphous matrix.
- The TiBN coatings exhibited a significantly lower friction coefficient at room temperature compared to monolithic TiN coatings.
Conclusions:
- The PIIID technique successfully produced novel multilayer TiBN coatings.
- The incorporation of hexagonal BN within the multilayer structure is crucial for reducing friction.
- These TiBN coatings show promise for applications requiring low friction and wear resistance.
