The presented article considers the disadvantages of chromium coatings and shows the possibility of their elimination by obtaining coatings of discrete structure. The principle of coatings of discrete structure allows to organically combine physical processes underlying pulse hardening methods with a discrete structure determining their service properties. It is shown and substantiated that the method of electric spark alloying is the most suitable for applying discrete coatings, since this process is discrete by its nature. The advantage of discrete coatings is the absence of a softening effe

Due to the low adhesion observed at the interface between solid and liquid, superhydrophobic coatings hold significant promise for various applications, such as self-cleaning, anti-corrosion, anti-icing, and drag reduction. However, a notable challenge hindering their widespread adoption in these domains lies in their delicate durability. In this study, we propose a straightforward method for preparation.

The article provides information about the stress state protective and decorative coatings during aging. The influence of the discrete nature of the substrate on the change in the stress state of the coatings from the action of the wind load is considered. It was revealed that for each type of coating there is its own critical value of the pore size (unfilled paint), the excess of which leads to cracking of the coatings. A method is proposed for selecting the optimal coating thickness.

Abstract Mathematical models were developed that can be used to predict the cathodic protection (CP) requirements for coated pipelines protected by parallel anodes. This work was motivated by the need to estimate the current and potential distribution on the pipe when anodes are placed near the pipeline or when discrete coating holidays expose bare steel. The mathematical model solves Laplace's equation for potential with boundary conditions appropriate for the pipe being protected, the anode, and any region through which current does not pass, such as the edge of a thaw bulb. The current dens

Abstract This paper presents the results of full-scale laboratory tests to evaluate the performance of a magnesium ribbon cathodic protection system designed for a large diameter pipeline. Tests were conducted on a 305 cm section of 122 cm OD pipe externally coated with fusion bonded epoxy in a pit filled with various water resistivity environments (5,000, 20,000, and 100,000 ohm-cm). Parameters that were studied included the number of magnesium ribbon anodes connected to the pipe (one to four), coating defect size and shape (discrete or multiple circular defects versus a slit defect that ran

Research into the induction and conduction coupling response of a pipeline co-located with an electric power transmission line to assess the high voltage coupling response under fault conditions. Capacitive discharge tests were performed on primarily fusion bonded epoxy and coal tar enamel coatings containing discrete individual holidays (circa 1985). A pipeline coating response model to high voltage stress was developed, but questions arose within the pipeline community as to the veracity of capacitate discharge coating testing when the coupling was from overhead alternating current electric
