Two commonly applied corrosion resistance coatings (Polyvinyl and Epoxy Polyamide resins) in Rivers and Bayelsa areas of Nigeria, have been compared on performance properties. The coatings were applied on low Carbon Steel samples that were cut to specific sizes. These prepared samples were subjected to varying conditions of pH, temperatures and exposure to definite time periods. The corrosion rates in ML per year (MPY) were then analyzed. The results of the corresponding corrosion rate in MPY obtained at PH 2,3,4,5, and 6, for epoxy polyamid resin, were 0.566, 0.553, 0.379, 0.354 and 0.322 respectively, and that for polyvinyl resin were 0.334, 0.326, 0.314, 0.288 and 0.277 respectively. The effect of temperature at 30° C, 4 ° C, 50° C, 60° C and 70°C were compared and corresponding corrosion rate in MP obtained for epoxy polyamide were 0.158, 0.288, 0.477, .655 and 0.810 respectively, while that for polyvinyl resin gave values of 0.122, 0.21 ,0.411, 0.552 and 0.651 respectively. The time exposure in hours of 692, 1008, 1344, 1680 and 2016 for the test steel samples applied with epoxy polyamide resin coating gave a corresponding corrosion values in MPY of 0.012, 0.016, 0.030, 0.043 and 0.055 respectively, and that for polyvinyl resin coating were 0.002, 0.009, 0.020, 0.034 and 0.044 respectively. The results obtained showed that polyvinyl resin coating have better performance properties over epoxy polyamide resin. Therefore polyvinyl resin coating can be recommended as a good corrosion resistance coating on low carbon steel pipes used in crude oil exploration in Petroleum industries

This study aims to analyze the corrosion penetration rate of low carbon steel with aluminium coating. The method used is the potentiodynamic method to determine the value of the corrosion rate. The corrosion medium used was HCl. The aluminium used is aluminium frame waste powder. The coating process is by dipping low carbon steel pipes into aluminium frame waste that had been liquefied in the Hot Dip Galvanizing (HDG) method of 700oC and immersion time of 45 seconds. The results of this study show that low carbon steel which has been coated with aluminum frame waste powder has a high corrosion rate which is proven to have a corrosion rate of 18,1808 mm/year. So that the corrosion rate is at an unacceptable level.

Abstract Corrosion rate data are presented for low carbon steel in (1) a combination of sulfur dioxide, water vapor and air, and (2) aqueous solutions of sulfurous acid in the absence of air, at ordinary temperature. Information as to the nature of the corrosion products is presented and it is shown that this depends on the place in which the corrosion takes place to an important extent.

Corrosion-resistant metals and alloys towards liquid metals determine the service performances and lifetime of the devices employing liquid metals. This paper studies the static corrosion behaviors of iron, chromium, nickel, low carbon steel, and four types of stainless steels (SS410, SS430, SS304, SS316L) in liquid Sb-Sn at 500 oC, aiming to screen corrosion-resistant SS for Li||Sb-Sn liquid metal batteries (LMBs). The corrosion rates of Fe and Ni are 0.94 μm h-1 and 6.03 μm h-1 after 160 h’s measurement, respectively. Cr shows a low corrosion rate of < 0.05μm h-1, which is due to the formation of a relatively stable Cr-Sb layer that may be able to prevent the interdiffusion between the solid substrate and liquid Sb-Sn. Ni has a high corrosion rate because the formed Ni-Sb and Ni-Sn compounds are soluble in the liquid Sb-Sn. The corrosion products of both pure metals and SS can be predicted by thermodynamic and phase diagram analysis. Among the four types of SS, SS430 shows the best corrosion resistance towards liquid Sb-Sb with a corrosion rate of 0.19 μm h-1. Therefore, a liquid Sb-Sn resistant material should have a high Cr content and a low Ni content, and this principle is applicable to design metallic materials not only for LMBs but also for other devices employing liquid Sb- and Sn-containing liquid metals.

Good Agreement

The corrosion rates of low-carbon steel, and 304, 316 and 410/420 stainless steels in simulated geothermal media containing hydrogen sulfide have been measured by means of the polarization resistance technique. Good agreement was found between weight-loss and polarization resistance measurements of the corrosion rate for all the metals tested. Carbon steel formed a non-adherent film of mackinawite (Fe1 + xS). The lack of protection afforded to the steel by the film resulted in an approximately constant corrosion rate. The stainless steels also exhibited corrosion rates that were independent of time. However, the 410 and 420 alloys formed an adherent film consisting mainly of troilite ( FeS ) which provided only limited passivity. In contrast, the 304 and 316 alloys appeared to be essentially protected by a passive film which did not seem to involve an iron sulfide phase. However, all the stainless steels, particularly the 410 and 420 alloys, showed pitting, which indicated that some breakdown of the passive films occurred.

Chromium pre-treatments of metal have been replaced by silane pre-treatments as more environmental friendly option. Nanoparticles can be added in the silane sol-gel network have been reported to improve corrosion resistance. In this work, the electrochemical corrosion resistance of low carbon steel coated with hybrid organic-inorganic sol-gel film filled with nanoparticles was evaluated. The sol-gel films have been synthesized from 3-glycidoxy-propyl-trimethoxy-silane (3-GPTMS) and tetra-ethyl-ortho-silicate (TEOS) precursors. These films have been impregnated with 300 ppm of silica or alumina nanoparticles. The electrochemical behavior of the coated steel was evaluated by means of electrochemical impedance spectroscopy (EIS) and scanning electron microscopy (SEM). Equivalent circuit modeling, used for quantifying the EIS measurements showed that sol-gel films containing silica nanoparticles improved the barrier properties of the silane coating. The silica nanoparticle-containing films showed highest initial pore resistance over the five days of immersion in 0.05M NaCl.
