“…The design involves different tribological issues, such as wear or damage of various components (shafts, bearings, and gears). Scientific research followed the trend, and several works analyzed lubricant and material [183][184][185][186][187][188] improvement, causes of failure [189][190][191][192][193][194], monitoring and modeling [193,195] techniques, and efficiency evaluation [196][197][198] of wind-power and hydropower systems.…”

Sustainability has become of paramount importance, as evidenced by the increasing number of norms and regulations concerning various sectors. Due to its intrinsic trans-sectorial nature, tribology has drawn the attention of the supporters of sustainability. This discipline allows the environmental, economic, and social impacts to be decreased in a wide range of applications following the same strategies. In 2010, Nosonovsky and Bhushan drew up 12 approaches based on the 12 principles of green chemistry and the 12 principles of green engineering, defining the “12 principles of green tribology.” This review exploits the 12 principles of green tribology to fathom the developed research related to sustainability and tribology. Different approaches and innovative studies have been proposed in this short selection as references to consider for further development, pursuing the efforts of the scientific community for a sustainable future through the contribution also of tribosystems. The manuscript aims to provide practical examples of materials, lubricants, strategies, and technologies that have contributed to the overall progress of tribology, decreasing wear and friction and increasing efficiency, and at the same time promoting sustainable development, lowering toxicity, waste production, and loss of energy and resources.

“…A. Kumari et al 18 investigated the typical premature failure of water wall tubes of two thermal power plant boilers with the same capacity, the same operational parameters, but with different boiler-water chemistry compositions, and the cause of corrosion was identified and the proposed strategies for their elimination were given. M. Nurbanasari et al 19 reported a failure analysis on the water-cooling distribution pipe in a 175-MW hydroelectric power plant, the results strongly evidence that the leakage occurred on the base metal due to the severe erosion-corrosion at the localized area. A. D. Camilo et al 20 have studied the causes of failure of boiler water-cooled tube wall.…”

In the present research, the leakage causes of a boiler water-wall tube, with an outside diameter of 60 mm and a thickness of 6.75 mm, that transmits the water medium have been studied. Leakage occurred on the fire-facing side of the tube and close to the boiler. Various techniques including visual inspection, chemical composition analysis, Vickers hardness test, tube wall thickness measurements, mechanical performance testing, optical microscopy and energy-dispersive spectroscopy were carried out to verify the probable cause of failure. Deposits formed on the inner wall of the tube, which caused local heat-transfer performance of the tube to decrease, formed an overheating characteristic in the microstructure, and softened the tube wall and made the tube wall thinner near the leakage points. The softening of the tube wall reduces the measured hardness at the edge of the leakage point. In addition, due to the localized wall thinning and softening, the tube cannot withstand the stress flowing liquids and gases, with the result that the tube was bulging and deforming. Local overheating caused the degeneration of the initial ferrite-pearlite microstructure. In the microstructure near the leakage point of the water-wall tube, carbides were spheroidized and coalesced. According to the investigation, it was concluded that the local heat-transfer performance of the water-wall tube decreased and the tube performance deteriorated due to the deposits formed on the inner surface. The combination of localized overheating and tube wall thinning led to the tube's premature bulging and failure while running.
