Corrosion behaviour of cast iron and low alloy steel in cocoa liquor and well water was investigated. The average weight losses of the specimens were measured using digital weighing balance. The results showed that the weight losses of both cast iron Assessing the effect of copper additions on the Assessing the effect of copper additions on the corrosion behaviour of grey cast iron Saliu O. SEIDU, Seun S. OWOEYE, Helen T. OWOYEMI 50 Introduction Grey cast iron is one of the most widely used metallic materials, because of its good castability, excellent machinability, relatively low cost and unique properties [1, 2]. Due to
Olawale et al. have evaluated the corrosion behavior of grey cast iron (GCI) and low alloy steel (LAS) in cocoa liquor and well water and found that LAS has better corrosion resistance than GCI in both media, and cocoa liquor is more aggressive than well water. Corrosion behavior of 0.022.0wt% Vanadium alloyed grey ironAbstract:This paper focused on corrosion behavior of grey cast iron having 0.02wt %, 0.5wt% and 2wt% vanadium as the alloying elements. Vanadium alloyed grey cast iron samples were produced by using Y - block CO 2 sand casting process and poured into double cylinder mould. The corrosion behavior was measured from polarization method, under 3.5% NaCl aqueous solution, conducted at Corrosion of cast iron - University of BabylonThe corrosion behavior of cast iron in different aqueous salt solutions has been studied. Samples of cast iron were exposed in the salt solutions media for 40 days and corrosion rates evaluated, using total immersion test and Tafel extrapolation curves. The concentration of salts taken is 5 g/liter. The total immersion test parameters vise
Corrosion behaviour of cast iron and low alloy steel in cocoa liquor and well water was investigated. The average weight losses of the specimens were measured using digital weighing balance. The results showed that the weight losses of both cast iron and low alloy steel in both media increases with time. Experimental Investigation of Corrosion of Cast Iron Electric and hybrid vehicles use regenerative braking, where application of the brake triggers the electric motor to drive as a generator to produce electricity, which in turn charges the battery. Although allowing use of up to ~60% of the kinetic energy of a vehicle, this ?electric braking? action is usually combined with the use of a friction brake, often called foundation brake, in the Experimental Investigation on Corrosion of Cast Iron PipesIt is well known that corrosion is the predominant mechanism for the deterioration of cast iron pipes, leading to the reduction of pipe capacity and ultimate collapse of the pipes. In order to assess the remaining service life of corroded cast iron pipes, it is imperative to understand the mechanisms of corrosion over a long term and to develop models for pipe deterioration.
Cast iron was used in the water industry prior to 1970 and a large number of cast iron pipes still remain as trunk mains. These pipes have been subjected to different levels of corrosion and variety of loading conditions. This leads cast iron pipes to fail in the field without prior warning. Graphitic Corrosion in Grey Cast Iron - Anderson Materials A grey cast iron pipe that has undergone graphitic corrosion often visually appears to be fine other then some general surface corrosion. However, due to possible subsurface attack a substantial portion of a pipes wall thickness can be converted to a weak and brittle graphite network with dramatically reduced mechanical strength.

These procedures include (a) representative sampling of components sensitive to selective corrosion, (b) the visual inspection, and (c) the hardness test, respectively. For an exact analysis, additional laboratory testing is recommended. The methodology is most applicable to grey cast iron and copper alloy with more than 15 % zinc. Improving the corrosion and wear resistance of grey cast The corrosion properties of the parent lamellar grey cast iron were greatly enhanced by the surface layers, but inferior to duplex stainless steel. With additional metallographic investigations the corrosion mechanisms were investigated. Microstructure and properties of Cu-Ti-Ni composite Feb 01, 2020 · Fig. 3 shows the XRD diffraction patterns of the gray cast iron and the coating. The gray cast iron presents the characteristic diffraction peaks of -Fe (ferrite) (PDF-87-0721), and the coating is mainly composed of -Cu (PDF-85-1236), TiC (PDF-71-0298), (Fe, Ni) (PDF-47-1417) and CFe 15.1 (-Fe austenite) (PDF-52-0512). It is clear that
Gray cast iron has many applications as pipes , pumps and valve bodies where it has influenced by heat and contact with other solutions . This research has studied the corrosion behavior and Wear behaviour of grey cast iron with the presence of Oct 11, 2018 · The overarching aim of this article was to examine the surface wear behaviour of grey cast iron in the presence of added copper with different proportions under different working conditions, applied pressure, rotational speed and test duration.
