Improved mechanical properties of W-Zr-B coatings deposited by hybrid RF magnetron – PLD method
Abstract
<p>In this work, novel W-Zr-B coatings were developed by a hybrid process combining pulsed laser deposited ZrB<sub>2</sub> and radio frequency magnetron sputtered W<sub>2</sub>B<sub>5</sub>. The influence of the laser power density on the structure and mechanical properties of the deposited films was studied. Addition of zirconium causes a change in the structure of the deposited films from columnar to mainly amorphous. The nanoindentation tests and compression of nanopillars showed that doped W-Zr-B layers are still super-hard and incompressible in comparison to WB<sub>2</sub> films without doping, but they change their behaviour from brittle to ductile. Films obtained with a fluence of 1.06 J/cm<sup>2</sup> are superhard (H = 40 ± 4 GPa) and incompressible (12 ± 1 GPa), but possess a relatively low Young's modulus (E = 330 ± 32 GPa) and a high elastic recovery (W<sub>e</sub> = 0.9). Further increase in the fluence causes films to consist of deeply embedded fragments of laser ablated ZrB<sub>2</sub> target in the deposited layer. Taking into account that the particles are made of ZrB<sub>2</sub> which possess extraordinary thermal properties, and the matrix is made of W-Zr-B, a super-hard material, such a composite can also be interesting for industrial applications.</p>
