1. Introduction. Erosion-corrosion of slurry consisting of corrosive medium with solid particles is a common problem in many engineering fields such as metallurgy, power plant, mining, and chemical industry, and it is recognized as the major reason for the damage of the flow components, e.g., impeller of pump, pipeline, elbow, and choke (valve/nozzle) [1,2,3,4].Cited by: 3.

Synergistic effect between corrosion and wear has been widely recognized in many tribo-corrosion systems.

In most wet application conditions, dissolved oxygen (DO) is a controlling factor to the dynamics of corrosion process and is therefore expected to have significant impact on the tribo-corrosion performance of materials.

In this study, the effect of DO (0–24 ppm) on erosion–corrosion Cited by: 5. Erosion. Erosion corrosion is an acceleration in the rate of corrosion attack in metal due to the relative motion of a corrosive fluid and a metal surface. The increased turbulence caused by pitting on the internal surfaces of a tube can result in rapidly increasing erosion rates and eventually a leak.

Erosion-corrosion. This is caused by the flowing movement between a corrosive fluid and a metal surface. This process leads to the formation of groove valleys, wavy surfaces and holes. Each form of this type of corrosion will have a directional appearance on the metal surface that will mimic that of the fluid.

Slurry pipelines offer an economic advantage over railroad transport and much less noise disturbance to the environment, particularly when mines are in extremely remote areas. Pipelines must be suitably engineered to resist abrasion from the solids as well as corrosion from the soil.

Erosion corrosion is a degradation of material surface due to mechanical action, often by impinging liquid, abrasion by a slurry, particles suspended in fast flowing liquid or gas, bubbles or droplets, cavitation, mechanism can be described as follows: mechanical erosion of the material, or protective (or passive) oxide layer on its surface.
