Summary, etc. <p>Nickel-phosphorus-titanium  oxide  coating  was  fabricated  on  the  AISI  304L  steel  substrate  using  the  electroplating  method.  Electroplating  was  performed  at  temperatures  of  55,  60  and  65  °C,  and  the  effect  of  electroplating  temperature  on  microstructure,  corrosion  behavior,  and  wear  behavior  was  investigated.  The  coatings  were  characterized  by  use  of  scanning  electron  microscopy  (SEM).  In  order  to  investigate  corrosion  resistance,  potentiodynamic  polarization  and  electrochemical  impedance  spectroscopy  (EIS)  tests  were  performed  in  3.5%  of  NaCl  aqueous  solution.  A  pin  on  disk  test  was  employed  to  investigate  the  wear  resistance  of  uncoated  and  coated  samples.  Sample  micro-hardness  was  also  measured  by  the  Vickers  hardness  test.  The  results  of  potentiodynamic  polarization  and  electrochemical  impedance  spectroscopy  tests  results  showed  that  the  coating  created  at  temperature  of  60  °C  had  the  highest  corrosion  resistance  (7058  Ω.cm<sup>2</sup>)  compared  to  coated  sample  at  temperature  of  55  °C  (2115  Ω.cm<sup>2</sup>)  and  65  °C  (2289  Ω.cm<sup>2</sup>).  Also,  the  results  of  the  wear  and  micro-hardness  test  showed  that  composite  coating  formed  at  temperature  of  60  °C  had  the  highest  wear  resistance  and  micro-hardness  (677  Vickers)  compared  to  coated  sample  at  temperature  of  55  °C  (411  Vickers)  and  65  °C  (536  Vickers).</p>
