Abstract

Smart coatings enable sensing and actuation functionality to be added to materials. Piezoelectric coatings, especially lead zirconate titanate (PZT), have been extensively used on a wide range of metallic and semiconducting substrates. This paper demonstrates the first attempt at coating Pb0.52Zr0.48TiO3 onto the hard metal composite material Tungsten Carbide-Cobalt (WC-Co), which is extensively used in the metal processing industry due to its hardness and abrasion resistance.
The deposited PZT coating demonstrated rather low dielectric, ferroelectric and piezoelectric activity, for which may have contributed the formation of an oxide layer caused by the oxidation of the substrate during heat treatments. We suggest that the coating performance, and thus functional properties, can be improved by the addition of a buffer layer coated on the substrate.
