“…These types of corrosion can significantly reduce the lifespan of gas turbine parts. Type I hot corrosion (sulphidation and internal damage) takes place between 800 and 900 °C, whereas Type II hot corrosion (pitting) takes place between 600 and 750 °C [16]. Hot corrosion damage can be divided into two phases.…”

As modern air engines’ working temperatures are increasing, materials and coatings' hot corrosion resistance characteristics gain significant attention. Hot corrosion is a type of degradation at high temperatures that involves oxidizing or sulphidation of the substrate behind a layer of salt melt deposit, which either causes the development of a thick layer of sulphide scale or the penetration of sulphur via grain boundaries into the matrix to a deeper depth. It may notably change the microstructure, phase composition, and characteristics of the thermally sprayed coating. In recent years, thermally sprayed cermet coatings on steel have been more well-liked as a possible method for enhancing hot corrosion resistance. This review paper qualitatively summarizes the recent development of thermal sprayed coatings to improve hot corrosion performance.

Zinc has a successful history of being a protective coating on a wide range of objects and in many exposure settings due to its strong corrosion resistance in most environments. Because zinc may produce dense, adhering corrosion byproducts, it is resistant to corrosion. The industrial applications of zinc are extensive. Due to their excellent properties, zinc‐based coatings have garnered great attention in the modern world. The present study focuses on advances in surface modifications of zinc composite coatings through selective reinforcements. The study also includes a detailed description of recent experimental work conducted on zinc‐based coatings. Various coating techniques and their advantages and limitations have been discussed along with the relevant parameters. Zinc and its alloys have been suggested as viable options for biodegradable metals recently because of their acceptable biocompatibility and preferred corrosion behavior. The use of zinc‐based biodegradable materials in clinical applications like orthopedic and cardiovascular systems has also been discussed in detail. The current study also includes the latest developments in zinc‐based biodegradable metals and the related surface modification techniques. Future perspectives on zinc‐based alloys and their variety of applications have also been undertaken in the study.
