“…These observations all support the results and assumptions made in [19,21,22], which is that the erosion mechanism in the mass loss period is probably caused by low-cycle fatigue. Virgin surfaces with several small pits showing where tiny particles have subsequently been removed were found throughout the specimens, as were cracks and soon-to-be-removed chunks.…”

“…Low-cycle fatigue occurs when plastic deformation occurs with each loading, so that material failure happens after a relatively low number of loading cycles [20]. Balyts'kyi and Chmiel [21] found a correlation between cavitation erosion fracture and the low-cycle fatigue resistance of steel alloys. Aboul-Kasem, Emara, and Ahmed [22] studied the particles removed from the material at different stages of the cavitation erosion process using scanning electron microscopy (SEM).…”

Cavitation erosion is the most important erosion mechanism in Francis turbine runner blades. For this reason, knowledge of a material's ability to resist cavitation is important in defining how suitable it is for use in a Francis turbine. In this study, three Francis turbine materials were subjected to cavitation erosion in a high-speed cavitation tunnel. One of the materials was a low-alloy steel, and the other two were stainless steels. The cavitation tunnel produced an annular cavitation field on one face of a cylindrical specimen. The test specimens underwent cavitation erosion until the erosion had reached a maximum penetration depth of about 0.5 mm. The material surface profiles were measured at regular intervals to calculate volume and mass loss. These losses were compared to those of several other materials that had undergone the same tests with the same setup and operational parameters. The materials were compared according to their steadystate erosion rates. The steady-state erosion rate represents a material's ability to resist cavitation erosion once cavitation damage has already started to develop. The low-alloy steel eroded four times faster than the two stainless steels. One of the stainless steels tested here (Stainless steel 1) had the lowest erosion rate, along with another previously tested stainless steel. The other stainless steel (Stainless steel 2) had a slightly greater erosion rate than the first, falling into the same class as other lower-grade stainless steels and a nickel aluminum bronze alloy. The results show that in choosing a turbine blade material, stainless steels outperform Manuscript

“…-Older containers should not be used in transport of heavy cargo loads since it is hard to verify its technical condition especially when we take in account degradation of steels during the service. Balyts'kyi and Chmiel [8], and Balyts'kyi, Chmiel and Trojanowski [9] show that in similar conditions hull steel (that is similar to steel utilized in production of shipping containers) that impact toughness and low-cycle fatigue resistance decrease with time.…”

Currently, guidelines for safely loading shipping containers with heavy cargo in the gooseneck tunnel region do not exist. This work investigates the influence of the construction type of the gooseneck tunnel on the strength of the floor of the shipping container. The main objective is to develop guidelines for loading shipping containers with heavy cargo in the gooseneck tunnel region. This paper investigates strength of the floor using finite element method. The finite element analysis shows how the container's floor responds in the given loading scenarios.

“…On the other hand, the presence of an anode zinc layer in the high-proton environment may develop the hydrogen degradation process. Both processes, in combination with dynamic loads and environmental impact, characteristic for cargo handling facilities in sea ports, are conducive to fatigue and fatigue-corrosive destruction [57,58].…”

Issues of Corrosion and Degradation under Dusty Deposits of Energy Biomass

et al. 2021

The aim of the study is to identify and determine the role of microbial degradation taking place in dusty deposits in potential threats (i.e., destruction of protective coatings and development of corrosion) to the means of transport in conditions of transshipment of energy biomass. This paper presents the results of research on the impact of powdery fractions of wood biomass and biomass obtained from oil plants in the degradation of paint coatings and corrosion processes. During the research, exposure to simulated port climate, OM, SEM, and EDS studies were used. It has been found that the presence of the fraction containing protein compounds and amino acids (e.g., dust of rapeseed meal) stimulates the growth of microorganisms whose metabolism products favour the destruction of protective coatings and the development of corrosion. Under the same conditions, the destruction of protective zinc coatings has been observed. It was found that already 14 days of exposure to oily biomass deposits results in damage to paint coatings caused by microbiological processes. The 8-week exposure causes serious degradation of protective coatings and the base material itself. The biomass of wood origin, containing compounds of the tannin type, did not show as much aggressive activity as the biomass with protein compounds.
