Abstract
Abstract Professor R.M. Latanision was the 1994 recipient of the Willis Rodney Whitney Award sponsored by NACE International. The present work is taken from his award lecture at CORROSION/94 held in March 1994 in Baltimore, MD. Latanision discussed the interplay between corrosion science and corrosion engineering in advancing technology. His lecture focused on supercritical water oxidation and other technologies that have been under study in the H.H. Uhlig Corrosion Laboratory and in which the chemical properties of new materials and traditional materials have proven integral to the development of contemporary or advanced engineering systems.

Abstract The process of supercritical water oxidation (SCWO) is a promising alternative to the incineration of aqueous organic waste streams and has received an enormous interest during the last decade. However, SCWO as an end-of-pipe technology has some disadvantages that have hindered an industrial application of the process. Beside technical problems due to reactor corrosion and salt precipitation, problems result from the fact that SCWO often is claimed as a “general” technology for all poss...

This study investigates the stress corrosion cracking of Ni-based (alloys UNS N 06625 and UNS N 06030) and Fe-based alloys (superaustenitic UNS S 31266 and superduplex UNS S 32550 stainless steels) in supercritical water as function of the water chemistry. Special attention is given to the effect of chlorides, temperature and plastic strain. Initiation and propagation of cracks is studied under controlled static loading conditions. Slow strain rate tests are also performed to assess the influenc...

Using the steel containing 0.45 percent of carbon as matrix, high carbon ferrochrome as cast-penetrated agent, the steel-based surface composites were fabricated by conventional cast-penetrating process combined with the thermite reaction. The influence of thermite reaction on the microstructures and properties of cast-infiltration layer was researched. The results show that the interfacial bonding is metallurgical fusion between cast-infiltration layer and the matrix under the suitable technolo...

SCWO, sometimes referred to as hydrothermal waste processing, uses the solvating traits of water in its supercritical condition to effectively destroy liquid organic wastes. One major problem in the supercritical water oxidation process is corrosion, because all metallic tubes in the process are exposed to high temperature and high pressure as well as severe corrosive species such as Cl−, F−, S2−, and O2−. The presence of Cl− when the pH of a solution is very low and the solution has excess oxyg...

Morphologies, microstructures and chemical composition of oxide films grown on Alloy 625 at 400 degrees C, 450 degrees C and 500 degrees C in oxidizing supercritical water containing 2.0% H2O2 were investigated using weight measurement, grazing incidence X-ray diffractometry, scanning electron microscopy, X-ray photoelectron spectroscopy and transmission electron microscopy. It was found that the mass gain of the alloy in oxidizing supercritical water increased with exposure time. The smallest m...

Abstract Typical materials for applications in high-temperature, high-pressure aqueous solutions are stainless steels, nickel-base alloys, titanium, tantalum, noble metals, or ceramics. Under these conditions, these materials are often severely attacked, especially in the presence of acids, salts, or gases. Corrosion phenomena in high-temperature aqueous solutions are mainly influenced by the following factors: dissociation of acids, salts, and bases, the solubility of gases, the solubilities of...

Abstract In the present paper, in situ electrical and electrochemical measurements during oxidation of pure Ni in ultrasupercritical water (500–600 °C) have been performed and analysed. The onset of oxidation was followed using contact electric resistance measurements. The impedance spectra of the Ni–Ni contact during oxidation could be quantitatively interpreted using general considerations of the corrosion process and the Mixed-Conduction Model for oxide films. Preliminary estimates of the dif...

Water can be used effectively as solvent in pressurized hot water extraction (PHWE) because the physico-chemical properties of water are readily altered through changes in temperature and pressure. Temperature is the main parameter affecting extraction, but time and flow rate are also essential in solubility-limited extractions. PHWE has been applied to a variety of analytical extractions (e.g., organic pollutants, pesticides, flavors, fragrances, and metals). PHWE has often shown similar or bet...

B4Cp/2024Al composite with volume fraction of 45% was designed and fabricated by pressure infiltration technology. Microstructure and friction and wear properties of B4Cp/2024Al composites were studied. The results show that reinforcement particles are uniformly distributed and a qualified relative density of the composite has been achieved. A high density of dislocations was observed to be in the peripheral area of the reinforcement particles, and a large number of fine acicular precipitates we...

Abstract In order to improve the wetting properties of graphite with Al melt and reduce the oxidation of the graphite, by which the segregation of components during the liquid-stir-casting process could be prevented. In this paper, a uniform thin nano-film of CeO 2 , about 20 nm thick, was successfully prepared onto graphite powder surface by heterogeneous nu-cleation process. The results show that an obvious chemical reaction did exit between CeO 2 film and graphite with the formation of Ce-O-C...
