(55.18°) respectively, which are the characteristics peak of anatase phase. The surface
morphological analysis of the TiO 2 coated 304L SS using AFM is shown in Fig. 6.8a-d. Figure.
6.8a represents the morphology of TiO 2 coated 304L SS. The morphology showed well organized,
evenly spaced, and compact arrangement of particles covering the surface. The histogram for size
distribution of the particles as a function of frequency of formation is shown in Fig. 6.8b. The
particle size ranges from, 1.5×10 -1 µm 2 to 1.12 µm 2 . However, because of agglomeration the size
of the particle increases up to 2.5 µm 2 . The exact location, and morphology of the pores on the
coated surface is shown in Fig. 6.8c. The size of the pores ranges from, 3×10 -3 µm 2 to 450 ×10 -3
µm 2 (Fig. 6.8d). The root mean square roughness (R q ) on the surface was 10 nm.
