MUT of corrosion's reliability has been very limited, according to the bulk of the study, which was mainly based on MUT of weldments. Although improving the tactility of scanning a component, it will do so by ensuring that probe coupling is maintained to the Carbon Steel surface when working in a variety of roles while also improving the tactility of scanning a component. When the technician is not manually attempting to hold the probe to the test piece, it can be immediately apparent. The MPC will be tested by a corrosion inspections laboratory to validate the MPC, and the results will show the MPC's effectiveness.

In 0. 5 M H_2SO_4 and CH_3COOH acidic solutions, this research investigated the role of date palm seed as a green corrosion inhibitor for carbon steel. Due to the acid strength of both acids, date palm seed extract in H_2SO_4 and CH_3COOH differs in H_2SO_4 and CH_3COOH, and it shows that the date palm seed extract can be used to shield carbon steel from corrosion attack.

Several forms of corrosion pits will influence laser treatment's success for surface preparation of severely damaged steel structures. Laser irradiation was used to determine the effects of laser treatment on the steel surface with corrosion pits, carbon steels with artificial pits of various depths and widths were installed and treated by laser irradiation in order to investigate the impact of laser treatment on the steel surface with corrosion pits, carbon steels with various depths and widths.

Carbon steel can easily be corroded in marine environments, particularly at high temperature and wet environments. When exposed to high temperatures, the oxide layer that formed on the carbon steel surface behaves as a deposit non-protective layer. Consequently, the carbon steel's surface must be coated with a metal that can be formed oxide surface and intermetallic layer that will shield the carbon steel from high-temperature corrosion. At different molten temperatures and dipping times, the optimal thickness coating was obtained by implementing the hot dipping coating process using pure Al at different molten temperatures and dipping time. On the carbon steel surface, the outer Al layer, and the inner aluminide layer, two layers were deposited, according to the hot dipping process. This is because the lanthnum film's plasticity and adhesion capability of Al_2O_3 film, which includes a lanthnum component, led to the production of a protective oxide film and a decrease in the number and numbers of void formation at the aluminide layer. In comparison to dry oxygen, water vapour presence in the oxidant gas atmospheres contributes to rapid degradation of aluminide layer caused by the emergence of voids and cracks that led to oxidation. In conclusion, in lieu of lanthanum in aluminizing up to 0. 3 percentwt, we can reduce carbon steel corrosion rate at elevated temperature in flowing of atmospheric air, dry, and wet oxygen gases.

Certain amounts of CO_2 gas are present in the pipeline system environment, which is used to transport oil and gas. This report investigates the carbon steel surface characterization in a CO_2 environment with the presence of sulphate reducing bacteria. Sulphur presence on metal specimens exposed to SRB in CO_2 environments that promote the formation of the FeS layer was found by the FESEM study. In samples exposed to the SRB, FeS was found by the XRD method.

The paper discusses a new method of honing with experimental cryogenic therapy that improves the machined surface of low-carbon steel products' machined surface. Based on this, the paper is dedicated to the development of a new method of honing using preliminary cryogenic treatment, which increases the quality of the processed surface of low-carbon steel products. The authors argued in the paper that the effect of hardness, wear resistance, and strength of the machined surface of austenitic and pearlitic steels' surface quality was demonstrated. In addition, the surface's micro-profile was investigated after machining stainless steel 12X18H10T by the traditional method of honing and honing with preliminary cryogenic treatment was investigated. For the improvement of the surface of a steels product made of steels 12X18H10T and 09 U04132C, the novelty lies in the plan of a new method for changing the composition of the workpiece material in order to improve the surface quality of a steel sheet product made from steels 12X18H10T and 09u04132C.

U201d is a trademark of the United States. The apparent superficial hardness measurements change from true to false as steel thickness decreases to zero thickness, despite a widespread lack of sample thickness for the superficial tests. A multi-step finite element analysis is used to show how material is deformed during a superficial hardness test and to determine the superficial hardness for a model thickness. The apparent superficial hardness for annealed steel is shown to be less than real hardness in the thickness range of 0. 5-1. 0 mm.

In this research, the connection between various micromagnetic signatures and three common carbon steels' surface hardness was investigated. For the quantitative determination of surface hardness in carbon steels, back-propagation neural network networks were developed. External validation experiments established the proposed two-step modelling scheme incorporating the K-nearest neighbor classification algorithm with the BP-NN modeling scheme.

To improve carbon steel's strength, nanocomposite coatings are increasingly being used in marine industries. After preliminary runs of the experiment, coated samples were produced containing ZrB_2 nanoparticles of 7 and 13 g Lu22121, at cell voltages of 0. 3 and 0. 5 V, and at a steady temperature of 45 u00b0C. The coating rate of the coated samples was determined in a 3. 50 wt. % NaCl solution using potentiodynamic polarization process according to ASTM specification, but a pin-on-disc tribometer was used to determine the wear volume. These corrosion property values provided significant shielding of the carbon steelu2019s main sites, according to these corrosion property values. The wear volume of the ZrB_2 coated steel was also reduced from 0. 0508 mm/u22123 for the uncoated carbon steel to a minimum value of 0. 00285 mm/u22123, which was attributed to the ZrB_2 nanoparticles' dispersion-strengthening and self-lubrication capabilities.
