“…In general, the crystallization of TiO 2 films followed as: anatase → anatase + rutile → rutile, when calcination temperature was increased from 50 to 600°C . To obtain anatase phase, different calcination conditions (450°C; 0.5 h, 550°C; 1 h and 500°C; 1 h, 400–900°C; 1 h) were reported in several studies. In another attempt, to improve crystallinity of anatase phase, PEG was used as an additive to increase calcination temperature to 500°C for 4 h without formation of any rutile phase.…”

Titanium oxide (TiO2) nanoparticle coatings were deposited on the 316L stainless steel substrates by sol‐gel method. The morphology, structure, and corrosion resistance of the coating were analyzed using SEM, AFM, X‐ray diffraction, and electrochemical techniques. The deposition parameters employed to realize the anticorrosion performance including calcinations temperature, polyethylene glycol (PEG) content, pH value, and number of dipping cycles were investigated. Taguchi statistical experiments were carried out to determine the influence of the deposition variables on anticorrosion properties and optimal conditions. The results indicated that a higher anticorrosion performance of TiO2 films could be achieved using 1 g of PEG in a sol with pH in range of 7–9, six cycles of dipping, and calcination temperature at 400°C. The Tafel polarization measurements indicate that icorr value decreases about 200 times and the Rcorr value increases around 57 times compared with uncoated 316L stainless steel.

“…The result of the wear assessment shows a progressive trend, as that of the hardness behaviour correspondent. From all observations, the structural evolution is seen to significantly impact on the inclination tendency of plastic deformation, although [5,6] mentioned that the control of microstructure plays a vital role on the wear movement, as seen in …”

“…Electrodeposition is an appreciable technique that has been known to proffer superior advantage over other functional applications, mainly due to its excellent performance [5], although the challenge of co-deposition has been the stability and formation of bath, based on the nature of coating. The kind of bath constituents is known to influence the nature of coating, and it is stated that properties of binary alloy deposits are advantageous, based on the resilient characteristics of metal or composite embedded in the bath [6][7]. From the assertion made by [1][2][3] [8,9], the plating parameters such as current density, rate of agitation, temperature range, bath constituents' concentration and pH, determine the fraction in which two or more metals uniformly co-deposit to have good surface modified coatings [10].…”

The need to improve the structural properties of materials in petrochemical industry, due to recurring failure, has motivated this study. The effect of deposition potential on structural integrity, surface topography and micromechanical progression of Zn based induced aluminium and TiO2 alloy coating series on mild steel was studied. The wear stability and microhardness behaviour of the developed composite coating was examined via, respectively, sliding reciprocating rig and dura scan diamond based microhardness tester. The structural reliability was inspected with scanning electron microscope equipped with EDS, and atomic force microscope. The results showed that the superb structural crystal resulted into a significant increase in the microhardness, and into a decrease in wear plastic deformation in a non-lubricated system. The precipitation of the deposits enforces stable crystal orientation and compact grains growth. The work has established that up to 13wt% TiO2 on zinc rich bath, a solid composite coating on mild steel, can be used to improve the service life of coating for stable structural properties.

“…In order to achieve a faster response with robust film structure which is more reluctant in acidic, alkaline and organic solvent, the choice of gate materials is very critical [4]. TiO 2 has received much attention due to its superior chemical stability, non-toxicity, high permittivity and refractivity with extraordinary photo-induced reactivity under illumination (E g > 3.2 eV for anatase TiO 2 ).…”

In this study, a sol-gel titanium dioxide (TiO 2 ) was spin-coated on indium tin oxide (ITO) substrate as a sensing membrane for the extended-gate field-effect transistor (EGFET). To improve its sensing properties, the resultant films were thermal annealed at various temperatures. It shows that, as TiO 2 was post-annealed at T a =200 o C for 30 min, a highest pH sensitivity of 79.9 ȝA/pH was derived. As T a > 500 o C, the pH sensitivity was declined substantial to 70.1 ȝA/pH. The sensitivity would further deteriorate to 61.8 ȝA/pH as the annealing time extended to 90 min under identical T a . These phenomena could be attributed to the less surface hydroxyl sites of TiO 2 thin film at elevated T a . X-ray diffractograms indicates that an amorphous titania resides as T a < 200 o C which presents more surface hydroxyl sites than those of crystalline structures at elevated T a . It reveals that the pH sensitivity of EGFET was relied on the density of the surface hydroxyl structures. To employ to the portable sensing devices with desirable pH sensitivity, the post annealing of the asdeposited TiO 2 film is a crucial process.
