Peculiarities of erosion-corrosion processes

Tribology International, 1996
Abstract Investigations have been carried out on an erosion-corrosion apparatus to investigate the behaviour of corrosion-resistant highalloy iron-base materials containing hard phases. These materials had been optimized for increased wear resistance under complex stress conditions.

Erosion-Corrosion Measuring Devices

1990
Two instruments for the study and measurement of erosion-corrosion (EC) were developed and built: the erosion-corrosion unit (ECU) and the erosion-corrosion tester (ECT). These instruments simulate the shear and impact forces acting on industrial equipment to evaluate the corrosive wear effects of the fluid on the equipment and their interaction.

Erosion-Corrosion in Industrial Turbomachinery

Materials Performance, 2012
Erosion-corrosion (EC) reduces the service life of turbomachines handling slurries. EC is a particular type of corrosion caused by the interaction of mechanical, hydrodynamic, chemical, and electrochemical processes acting on the surface of the equipment in various industries, including mineral, chemical, energy, and water.

Hydromechanical Measurements for Erosion Corrosion

CORROSION 1990, 1990
Abstract Laser Doppler anemometry and flow visualisation were used for hydromechanical characterization of various pipe flow geometries in both one-phase and two-phase flows (particle-containing liquids). The flow velocity fields of pipe expansions, constrictions and orifices as well as of VAM joints (simulated pipe connections) were ...

Erosive-Corrosive Wear of Copper

Journal of Lubrication Technology, 1977
Copper specimens whose temperature was varied from room temperature to 500°C were eroded by sand particles. The amount of metal removed increased monotonically over this temperature range except for temperatures between 350 and 425°C. Within this temperature band the erosive action prevented spalling, and thus had a beneficial effect in reducing the ...

Velocity Limits for Erosion-Corrosion

Offshore Technology Conference, 1985
ABSTRACT Erosion-corrosion is a form of metal degradation which can rapidly destroy down hole tubing and other equipment. API Recommended Practice 14E contains recommended fluid velocity limits for process piping on offshore platforms. In recent years the 1imiting velocity recommendations of API RP

Erosion-Corrosion Mitigation Using Chemicals

CORROSION 2003, 2003
Abstract Erosion-corrosion is a complex mechanism of material degradation resulting from interactions between electrochemical and mechanical processes. The consequences of erosion-corrosion are severe with economic penalties resulting from premature failure of components, increased downtime and increased maintenance costs.

Erosion and Erosion-Corrosion

2007
Abstract This chapter discusses the erosion and erosion-corrosion behaviors of metals and alloys. It includes data primarily related to particle-laden gas streams impacting on the metal surface. It also covers properties and applications and provides guidelines for materials selection.

Erosion-Corrosion in Industrial Steam Turbines

Materials Performance, 2009
Steam turbines are critical components of thermal power stations for generation of electricity. Erosion-corrosion results from the synergistic action of mechanical erosion and electrochemical corrosion and is a common deterioration mechanism. High-purity steam with low carry-over and the application of corrosion-resistant alloys will prevent corrosion ...

Erosion-Corrosion and Fretting

2018
This chapter presents the forms of corrosion related to the contact of a metallic surface with something moving on it, be it a fluid or another material. In the former case, erosion-corrosion phenomena may onset due to the rapid flow of a fluid on a metal, which combines corrosion with physical-mechanical interactions as turbulence, cavitation or ...
