The exhaust system has a number of requirements to fulfil. The major ones are to reduce the noise level created by the engine, to channel the waste gases out the rear of the automobile, to minimize the reduction in engine performance, and to have an acceptable service life and cost1. The exhaust system is divided into two main parts, the hot end and the cold end. The components comprising the h...
Solution chemistry of wastes from US atomic weapons production is controlled to inhibit corrosion of carbon steel tanks used in containment and storage. The pH, nitrate ion and nitrite ion concentrations of fresh solutions are maintained within specified limits for this purpose. In the start up process for a new waste evaporator (RHLWE), non-radioactive solutions of similar chemistry will be ci...
in this study, the four cr-mn-(ni-free) austenitic steels were fabricated by vacuum induction furnace. then plates with 10 mm thickness were fabricated by hot-rolling. corrosion behaviour of the four cr-mn steels in 0.1 m h2so4 solution was investigated using by open-circuit potential, potentiodynamic polarization, and electrochemical impedance spectroscopy (eis). the results indicated that the...
Heat-resisting alloys are designed to survive high-temperature oxidation by forming a slow-growing scale, usually Cr 2 O 3 , which acts as barrier between the metal and its environment. However, that succeed in this way when exposed hot oxygen or air fail do so CO gas. Instead, they exhibit rapid “breakaway” corrosion, developing oxides of alloy base iron and/or nickel. The growth these non-pro...
