“…Boiler tubes in thermal power plants are exposed to fly ash particles on impact that result in high-temperature erosion. Arc-sprayed coatings have been applied due to their excellent performance in withstanding corrosion, wear, and erosion at elevated temperatures [37]. Change in the cored wires' material composition by filling powder containing carbides (WC, Cr 3 C 2 ) or oxides (Al 2 O 3 , Cr 2 O 3 ) improves the service life of structures under high temperatures.…”

Among different thermal spraying methods, arc-spraying has been widely used due to its low operating costs and high deposition efficiency. The rapid progress of cored wire technology in arc-spraying has increased possibilities for the preparation of new Fe-based coating materials with enhanced properties by adding reinforcement particles and alloying elements to suit the different applications. Fe-based coatings have been extensively used because of their high strength, toughness, lower production costs, and availability of raw materials. This makes them suitable replacements for Ni-based coatings in ambient and high-temperature applications. This review discusses the research status and developments of the arc-sprayed Fe-based coatings. The study specifically reviews the wear behavior, corrosion analysis, and high-temperature resistant properties of arc-sprayed Fe-based coatings, aiming to develop an understanding of the protection mechanisms for Fe-based coatings. The performance of the Fe-based coatings depends on the integrity of the coating structure. Optimizing arc-spraying parameters minimizes defects (pores, grain boundaries, unmelted particles, oxides, and microcracks) that deteriorate the coating properties. High amorphous phase content, ceramic reinforcement particles and alloying elements enhance the corrosion, tribological, and high-temperature resistant properties of Fe-based coatings. In high-temperature applications, Fe-based coatings form oxide scales that protect the coating from further oxidation; thus, it is important to select the optimum composition for the alloying elements.

“…In addition, the major problems in thermal power plant are corrosion, oxidation and erosion. However, various authors [16][17][18][19][20][21][22][23][24][25][26][27][28][29] have used various types of coatings to combat high temperature oxidation, erosion corrosion. But, the use of AL in power plant can play a significant role.…”

The artificial intelligence (AI) plays a significant role in distinct fields to solve the complex problems. The digital technical field is increasing day by day in the world and it makes an internal part of our life. Hence, the knowledge of emerging technology is must for making our life easy. However, there are some major areas which are creating the problems to human such as agriculture field that comprises crop diseases, lack of storage management, pesticide control etc. These problems can be solved by artificial intelligence, IOT, machine learning and deep learning. Hence, the aim of this paper is to discuss the role of artificial intelligence to solve different issues of distinct sectors (medical, engineering, agriculture, business, defenses etc.) especially in medicine (COVID-19). Finally, future scope, challenges and application domain of artificial intelligence is also described.

“…The main function of CS coating is to cover the material surface and acting as a barrier preventing that, water, oxygen, chloride ions and other aggressive substance that react with the substrate and start its corrosion. In coal fired boiler erosion and high temperature corrosion is the main reason behind downtime (Kumar et al, 2019a(Kumar et al, , 2019b. Various authors used different E-C prevention techniques , but cold spray coating found to be useful in reducing maximum E-C of boiler tubes.…”

Purpose This paper aims to consolidate the results of various researchers focusing the different applications, so that this paper could become the torch bearer for the futuristic researchers working in the domain of cold gas dynamics spray coating. Design/methodology/approach A study on the cold spray coating is presented by summarizing the data present in literature. Important factors such as coating temperature, pressure, coating thickness, particle size, which affect the erosion-corrosion (E-C) resistance, physical and mechanical properties of boiler steel are stated. This paper also addresses the use of cold spray coating and compares it with other different thermal spray processes. Findings From the literature review, it was noticed that cold spray technology is best as compare to other thermal spray processes to reduce porosity, increase hardness, adhesion strength and retention in properties of feedstock powders. Originality/value Cold spray coating technology has a great potential in almost every field especially in restoration of surfaces, generation of complex surface, biomedical application, resist hot corrosion, wear, oxidation and erosion corrosion.
