“…These results were the same as those from a study of Hu et al (2012). In another study, ASTM 1045 mild steel was immersed in palm oil-based biodiesel (Jin et al 2015). The analysis of the results based on FT-IR spectral performed after 120 days showed the main corrosion products on used samples from biodiesel, namely a-FeOOH (1372.27 cm -1 ), b-FeOOH (881.84 cm -1 ), d-FeOOH (465.62 cm -1 , 1196.93 cm -1 , 1436.81 cm -1 ), and Fe2O2CO3 (609.17 cm -1 ).…”

“…This corrosion rate also increased along with the increase in biodiesel concentrations in a blend with diesel fuel (Cursaru et al 2014). In a study of Jin et al (Jin et al 2015), ASTM 1045 mild steel was used to immerse statically in pure palm biodiesel and diesel fuel at various temperatures, being 27 o C, 50 o C, and 80 o C, in order to assess the effect of fuel on the corrosiveness rate. After 30, 60 and 120 days of the test, the sample was removed from fuel.…”

Biodiesel, an environmentally-friendly bio-fuel, has been regarded as one of the most promising alternatives to fossil fuels whose use is rampant in the transportation sector. However, it is important that the corrosive effects of this fuel on engines are studied. This work reviews the corrosiveness that biodiesel exerts on various engine components, especially those made out of metals. First, an analysis of the corrosion mechanisms of metals exposed to biodiesel is provided. The conventional and advanced analysis methods will be applied to measure the level of corrosiveness in static immersion test, and to assess the formation of secondary products, if any, in biodiesel and any metal strips in contact with biodiesel-based fuel. The use of inhibitions to guard against corrosion will be mentioned. Lastly, several significant causes of metal corrosion, namely, the presence of dissolved oxygen and oxidation products, TAN change, a rise in dissolved water, the presence of metals, and the changes in biodiesel properties will also be presented. ©2019.

“…Considering that fuel temperature is a parameter for the corrosion rate as shown by Haseeb and Jing, and that fuel temperature mainly depends on the atmospheric temperature, biodiesel can be concluded to be more suitable for cold and temperate climates [16], [23].…”

ÖzRapid depletion of fossil fuel resources as well as concerns for foreign dependence in meeting energy needs have led researches for alternative fuels. Biodiesel, which can be obtained from many renewable resources such as vegetable oil and animal fat through transesterification, is the most attractive alternative fuel for cars, especially for being environmentally friendly. However, there are some cons, too. The presence of water and free fatty acids in the biodiesel makes it more corrosive than petrol-diesel, and this is an undesired feature. Corrosion induced by contact with biodiesel both reduces the life of metal parts and deteriorates the fuel properties, hence adversely affects engine performance. Therefore, the corrosive characteristics of biodiesel are very important for long term durability of engine components. In this study, we tried to investigate the corrosive effects of biodiesel and blends on engine parts by evaluating and comparing test results from earlier studies for different periods at different temperatures with different biodiesel fuels. Remedial measures to inhibit or mitigate corrosive effects of biodiesel by using additives are also tackled. Fosil yakıt kaynaklarının hızla tüketilmesi ve enerji ihtiyacının karşılanmasında dışa bağımlılık kaygısı, alternatif yakıt araştırmalarına yol açmıştır. Transesterifikasyon yoluyla bitkisel yağ ve hayvansal yağ gibi birçok yenilenebilir kaynağından elde edilebilen biyodizel, otomobiller için, özellikle çevre dostu olmak için en çekici alternatif yakıttır. Ancak bazı eksiler de var. Biyodizelde su ve serbest yağ asitleri varlığı onu petrol türevi dizelden daha korozif yapar ve bu istenmeyen bir özelliktir. Biyodizel ile temastan kaynaklanan korozyon hem metal parçaların ömrünü azaltır hem de yakıt özelliklerini kötüleştirir ve bu nedenle motor performansını olumsuz olarak etkiler. Bu nedenle, biyodizelin korozif özellikleri, motor bileşenlerinin uzun süreli dayanıklılığı için çok önemlidir. Bu çalışmada, farklı biyodizel yakıtlarıyla farklı sıcaklıklarda farklı dönemler için önceki çalışmaların test sonuçlarını değerlendirerek ve karşılaştırarak biyodizel ve harmanların motor parçaları üzerindeki korozif etkileri araştırılmıştır. Katkı maddeleri kullanarak biyodizelin korozif etkilerini önlemek veya azaltmak için düzeltici önlemler de ele alınmaktadır.

“…Materials, such as bronze, copper, steel, and aluminum, were tested in biodiesel, presenting corrosion effects and forming sediments, which increased the ionic conductivity of biofuel [18,19]. The influence of temperature and exposure time on the corrosion effects of palm biodiesel in 1045 carbon steel were also evaluated, observing that the increase of temperature promotes the oxidation-reduction reactions and long periods of exposure time allow a higher degradation state of biofuel, increasing the corrosive effects and making the damages by pitting more visible [20,21]. Corrosion immersion testing of biodiesel on gray cast iron showed that an increase of the temperature in the test affects the corrosion velocity, and that the iodine value (IV) of biodiesel is also related with corrosion effects, as highly unsaturated esters are more corrosive [22].…”

Corrosiveness of Palm Biodiesel in Gray Cast Iron Coated by Thermoreactive Diffusion Vanadium Carbide (VC) Coating

Palm biodiesel is a currently used biofuel, principally as an additive or substitute of diesel fuel in vehicular internal combustion engines. In the present work, vanadium carbide (VC) coatings were deposited on gray cast iron (GCI) using the thermoreactive diffusion process (TRD) to evaluate the corrosiveness of palm biodiesel and compare it with gray cast iron corrosion behavior. VC coated and uncoated gray cast iron samples were tested by immersion corrosion tests (291 K and 313 K), cyclic oxidation test (CO), and the electrochemical impedance spectrometry test (EIS). The corrosion test showed the reduction of the corrosion rate for the VC coating when compared to gray cast iron. EIS tests of coated samples showed higher values of polarization resistance when compared with uncoated gray cast iron samples. Results confirmed that while biodiesel was more corrosive than diesel on both coated and uncoated gray cast iron, the VC coating was efficient in protecting the substrate exposed to both fuels.
