What is Solid Particle Erosion?
Solid particle erosion (SPE) is a forfeiture of materials throughout repetitive influences of solid particles. Primary causes for the destruction of power generation mechanisms. In addition, 25% of all reservoir tube disasters are affected by solid particle erosion. Therefore, the proper selection and design of erosion resistant materials can extensively decrease the functioning cost of power generation. Moreover, there are multiple attempts have been completed to associate erosion resistance to voluntarily assessable mechanical characteristics.
In these characteristics include multiple factors such as hardness, yield along with fatigue strength, strain hardening coefficient, and ductility. Conversely, there is a complicated correlation to forecast erosion resistance having a single property and combination of properties have been developed. The need for a relationship between erosion resistance and mechanical properties can be recognized to the difference in strain ratios during conventional mechanical tests and erosion tests. Typically, strain ratios throughout varying from IO3 to IO s-1, whereas strain ratios during different mechanical tests such as hardness test and tensile test that vary from 10e4 to IOW. While SPE occupies high strain ratio deformation of an objective material, the erosion resistance could be correlated to high strain ratio of mechanical characteristics. Since Inconel-625 alloy has frequently used in power generation of different components. Erosion can be defined as the wear of a surface through relations with fluid and particles.
There are four types of erosion that can be identified:
- Solid Particle Erosion (SPE)
- Liquid Impingement Erosion (LIE)
- Hot Gas Erosion (HGE)
- Cavitation Erosion (CE).
It completely focuses on Solid Particle Erosion (SPE) of surfaces in merely mechanical ways. In fact, the different type of erosion along with most tribological processes for the issues that could be exhibit increased in material failure when corrosive nature is present. The method of SPE coated system that has been struggled to completely segregate in the mechanical material failure mechanics. Typically, the Solid Particle Erosion activities of a material that could be classified into two different kinds such as brittle or ductile as presented in figure 2. Therefore, ”brittle erosion” is considered by a maximum of “material failures” and the angle of incidence is should be normal, where the maximum of particle kinetic energy (KE) is relocated to target and degenerated by propagation along with intersection and crack initiation. On the other hand, the characterized by material exclusion during”plastic flow” (cutting or plowing) & characteristically presents maximum erosion with angles of incidence is very low that is (20 to 40 degrees).
