摘要: In the current study, TiO2 coatings on stainless steel substrates were prepared by Electrophoretic Deposition (EPD) of colloidal dispersions nanoparticles in ethanol. The effects deposition parameters surface morphology, phase composition and mechanical properties investigated. morphology EPD layers was observed using Atomic Force Microscopy (AFM). layer determined from peak intensity an X-ray Diffractometer (XRD) films investigated nanoindentation techniques. Characterization obtained atomic force microscope showed a relatively uniform microstructure. mainly consisted anatase rutile; is predominant with average percentage 71%. As result experiments, load–displacement curves two characteristics substrate – indentation hard-ness (HIT) modulus (EIT) calculated Oliver & Pharr’s approximation methods. Mechanical show improvement applied voltage. results illustrate that Young's hardness thin are increased increasing
