Wear characteristics and performance of composite alumina-zirconia CVD coatings

Wear behavior of DC unbalanced magnetron sputter deposited ZrCN films

“…Rie et al [15] deposited a group of Zr-based films and found good corrosive resistance of the ZrCN films. An analysis of ZrCN films revealed that they have lower coefficient of friction against various materials than a TiN film, with negligible degradation in mechanical and chemical properties [16].…”

Production of Al2O3‐Stabilized Tetragonal ZrO2 Nanoparticles for Thermal Barrier Coating

“…Moreover, there may be a chance of incomplete homogeneous mixing of precursor solution. The obtained 65:35 wt% ratio for Al 2 O 3 and ZrO 2 may be applicable for high‐temperature applications to improve the lifetime expectancy of the materials …”

“…Particularly, ZrO 2 content in the range of 30–40% is seen to be playing a crucial role in arresting the heat transfer of the substrate by reducing the delamination and cracking of the coating. It was also observed that higher content of ZrO 2 (more than 60%) is less suitable for such uses . The processing of sol–gel coating is one of the most widely used structural coating that can modify the surface properties of substrates without altering the nature of materials at low temperature .…”

Coatings

“…Russel and Strandberg [74] investigated the following multilayer CVD coating on WC-2.5 TiC -6 TaC ' 6 Co cemented carbide: ( and speed 244 m/min). A substantial improvement over AI203 coating in metal cutting was observed, where failure mechanisms were driven by high temperature and chemical diffusion.…”
