Effect of hydroxyapatite and yttria-stabilized zirconia nano-powders on surface integrity of Ti-6Al-4V in powder-mixed electrical discharge machining with multi-response optimization
This study investigated the influence of nano-powder type on the surface integrity of Ti-6Al-4V titanium alloy during powder-mixed electrical discharge machining (PMEDM). Three nano-powder conditions, namely hydroxyapatite (HA), yttria-stabilized zirconia (YSZ), and a mixed powder (50 wt.% HA + 50 wt.% YSZ), were dispe...
