The effect of graphite shapes on the electrochemical corrosion behavior of cast iron was studied by means of weight loss tests, electrochemical measurements and electron microscopy. It was found that the electrochemical corrosion behavior of graphite is significantly different from one other, and the corrosive potential difference between carbide ad the matrix is the main driving force of the different phase corrosions. Among them, the center A type and edge D type graphite exhibited the highest corrosion resistance. The corrosion of white iron is worst, because there are so many type carbides

Since the introduction of medical implants into human bodies, corrosion and wear have been regarded as key issues for their long-term durability. There has been a recent renewed interest in the use of large diameter metal-on-metal (MoM) hips, primarily because of the reduced volumetric wear compared with the wellestablished polyethylene-on-metal joints. Long term durability of MoM joints relies on control of both their corrosion resistance (relating to ion release) and wear behaviour (relating to creation of nanometre-scale wear debris).

Corrosion and corrosion prevention all have maintenance challenges and associated costs. The cost of preventative maintenance (which includes equipment), the cost of repair/overhaul and the potential cost of engine component mechanical breakdown that is due to corrosion. Ultimately, the benefits of having an intimate understanding of how corrosion occurs can lead to the correct decision making when participating in corrosion prevention measures. This paper will focus on the different types of operating environment, the types of internal and external corrosion, the materials and coatings used,

Abstract The inhibition effect of a kind of imidazoline base inhibitor on the corrosion of carbon steel under various conditions of pre-corrosion was studied using autoclave. Scanning electron microscopy (SEM) was used to characterize the steel surface. The results indicate the influence of pre-corrosion status on the corrosion rate and the effectiveness of corrosion inhibitor. Different kinds of corrosion products on the steel surface will play an important role on and significantly affect the inhibition effect.

Abstract Make up water for cooling water systems is diversifying because water shortage becomes serious issue in many countries. Recently RO treated water and process condensate have started to be used as make up water. Calcium hardness in make up water forms corrosion protection film on metal surface in cooling water. But RO treated water and process condensate are contained few calcium hardness. Therefore they show high corrosivity in comparison with normal fresh water. Phosphate and zinc have been generally used for corrosion inhibitor of heat exchanger tubes and piping in cooling water sys

Abstract Alloy 31 (UNS N08031, X1NiCrMoCu32-28-7) is a superaustenitic iron-nickel-chromium-molybdenum alloy with nitrogen addition filling the gap between existing stainless steels and nickel alloys. Alloy 59 (UNS N06059, NiCr23Mo16Al) with a high chromium, molybdenum and nickel content possesses excellent resistance not only to reducing but also to oxidizing chemicals. Both are already in use as shell materials for tank vehicles or tank containers. They allow the transport of quite more chemicals and especially waste mixtures than when using common austenitic steels. Another advantage is the

Abstract This paper describes a feasibility study on the injection of synergistic corrosion inhibitors for protection of concrete bridge components against corrosion. During this study corrosion inhibitors were developed that can be electrically injected into concrete matrices by an in situ technique. The results showed that such inhibitor injection can provide adequate corrosion protection to rebars embedded in chloride contaminated concrete. It was demonstrated that inhibitors injected can provide 78-85% corrosion protection for the rebars. Important advantages of this technology as against

The purpose of this project was to generate an accelerated corrosion methodology capable of producing seven-strand cables with simulated corrosive defects for calibration of nondestructive analysis (NDA) techniques. An additively manufactured accelerated corrosion cell was motivated and designed. Previous attempts at accelerated electrochemical corrosion used a large cable area with a current density that was too low (i.e., 1 A/m²)* to effectuate efficient corrosion. The accelerated corrosion cell presented here takes advantage of the restricted area within the corrosion flow cell to maximize

The main objective of the present project has been to develop a computer program, named GasCor, that can be used to estimate the corrosion related risk of operating dry gas pipelines under conditions where upsets may occur. An upset is here considered as an event that may cause corrosive liquid water to be present in some part of the pipeline within a certain time period. The computer program is meant to be a screening tool that can assist in the evaluation of the severity of the corrosion rate as well as in the location of the positions where the most significant corrosion is to be expected.

Gas quality specifications are set for commercial considerations and are influenced by several engineering factors including preventing corrosion, preventing blockages from freezing and hydrates, and the heating value of the gas. The Office of Pipeline Safety (OPS) Enforcement Manual for internal corrosion control states that the operator should have a procedure to determine if the gas is corrosive. Violation exists if (1) the corrosive potential of the gas is not determined by appropriate tests, and (2) suitable monitoring methods are not used to determine the effectiveness of steps taken to

Internal corrosion occurs where water or other corrosive electrolyte accumulates. This is the principle used in Internal Corrosion Direct Assessment (ICDA). Although ICDA focuses on nominally dry gas with episodes of water upset, the well accepted criteria for dry gas (e.g., water less than 7 lb/MMCF) may be significantly influenced by the presence of bacterial biofilms and hygroscopic solids, such as iron oxide corrosion products and some salts. Therefore, understanding the changes in dew point induced by the presence of these compounds is necessary to better quantify gas quality requirements
