In this study, critical heat flux (CHF) of Zirconium Silicide (ZrSi2) ATF coating for the zircaloy-4 (Zry-4) substrate has been assessed in flow boiling and enhanced by homogeneous porous surfaces fabricated by electrophoretic deposition (EPD). Three different porous structures were fabricated on physical vapor deposition (PVD) ZrSi2 coating using EPD. The particle size distribution, thickness, and porosity were adjusted by the changing process parameters of EPD to produce different porosity levels. Mean particle size and porosity of the EPD porous layer were increased by 35% and 21% respectively when the applied voltage was increased from 100 to 400 V. The CHF of the bare Zry-4, ZrSi-Zry, and ZrSi-Zrys modified by EPD (EPD ZrSi-Zrys) was evaluated in flow boiling at a mass flux of 300 kg/m2s. The optimized ZrSi2 coating modified by EPD enhanced the CHF of ZrSi-Zrys up to 146% when deposited at 400 V. Flow boiling enhancements of CHF of EPD ZrSi-Zrys were analyzed by evaluating liquid inflow rates of the surfaces.
