Experimental approach<br />
Nd:YAG laser<br />
Weight Pulsed laser beam<br />
Sample<br />
• Nd:YAG Q-switched<br />
nanosecond pulse laser<br />
• Samples manipulated in a raster<br />
fashion using CNC X-Y table<br />
• Change power intensity <strong>to</strong><br />
influence <strong>surface</strong> <strong>of</strong> PEEK<br />
• Contact angle measurement<br />
used <strong>to</strong> characterise <strong>surface</strong>s.<br />
• Resulting <strong>adhesion</strong> measured<br />
using single lap shear<br />
• FTIR and XPS conducted <strong>to</strong><br />
characterise <strong>surface</strong> chemistry<br />
