Electrochemical study on the corrosion behavior of Ti₃SiC₂ in 3.5% NaCl solution

Abstract

The differences between the Ti–C and Ti–Si chemical bonds limit the passivation ability, resulting in a decreased passivation ability.

Effect of Ti3SiC2 content on the corrosion behavior of Al/Ti3SiC2 composite coatings

“…Thus, it can be maintained that metastable oxide and hydroxide of Ti and Si are formed as part of the corrosion product. [38] A similar phenomenon was also reported by Travaglini et al, [41] who investigated the corrosion behavior of Ti 3 SiC 2 in several common acids.…”

“…It has high corrosion potential. [ 38 ] Thus, the probability for pit initiation is less than those in other areas.…”

“…[39] When compared with Ti 3 SiC 2 , a significantly lower ratio of Ti/C and Si/C indicates that the majority of Ti and Si atoms in the lattice have been selectively corroded into the solution and carbon has resided in the form of elemental substance. [7,8,19] According to Zhu et al, [38] regarding the corrosion of Ti 3 SiC 2 , as polarization potential increases, the passivation or corrosion process is modified; in this way, according to the PDM model, they demonstrated that the passivation films are formed by a bilayer structure. In general, the passivation in Ti 3 SiC 2 is combined with the oxide and hydroxide of Si and Ti.…”

Durability Testing of Photoelectrochemical Hydrogen Production under Day/Night Light Cycled Conditions

“…It is plausible that the decomposition of the epoxy sealant (probably forming vinyl radicals) in harsh acidic condition led to the carbon contamination. The negative shift of the Ti 2p due to relative increase of Ti 3+ peaks in the sample after the long‐term experiment is likely attributed to the hydroxide formation by the presence of H 2 O as described elsewhere ,. In the case of Pt 4 f, decrease of the Pt 2+ peak led to the slight negative shift and this might be due to reduction of the Pt‐DNS salt during a continuous reduction process (i. e., Pt metal formation).…”

Comparative Corrosion Studies on Alumina Plus Calcia Stabilized Zirconia Coatings Applied to Al6061 and Cast Iron Substrates

“…The chemical stability of ZnO applied on steel reinforced in concrete investigated using 3.5% NaCl and found that ZnO noticeably improve the corrosion resistance [8]Similar type of electrochemical experiment carried out on pure Titanium and Ti 3 SiC 2 in 3.5% NaCl aqueous solution and found Ti 3 SiC 2 as excellent corrosion inihibitor [9]. An interesting investigation of Ni-P-SiC coatings reveals that the nanoparticles distribution may influence the corrosion phenomenon [10]. A metallic cylinder liners which is one of the a critical component of internal combustion engine have to work under elevated temperature and frequently experience abrasive wear, corrosion/oxidation this leads to economic burden to the manufacturing industries.…”
