“…The experience of renovation and restoration of marine equipment suggests the appropriateness of using the latest approaches and technological solutions during the repair, because, in addition to restoring the equipment, they provide an extension of its life [5]. One of the progressive ways of developing this approach is a wider use of polymer composite and adhesive coatings [6,7].…”

“…It should be noted that the issue of theoretical substantiation and especially practical application of polymer composite materials for the restoration of marine equipment is being actively studied at present [1][2][3][4][5]14]. These studies are primarily aimed at increasing the adhesion of coatings to metallic and nonmetallic surfaces, reducing their degradation under marine conditions, and so on.…”

A new adhesive material and a restoration technology for marine equipment units are proposed. The optimal content of hardeners of different nature is found, and the effect of temperature conditions used for crosslinking epoxy resin DER-331, on the adhesive properties of the polymeric material is determined. The polymerization of the epoxy oligomer DER-331 and polyethylene polyamine (PEPA) hardener at a temperature T = 413 ± 2 K is found to enhance the adhesive properties of the polymeric material by 3.2–3.6 times, as compared to polymer GEN-150. In addition, the separation pattern of metal surfaces was analyzed, which allowed for an in-depth evaluation of the adhesive strength at separation and its variation upon increasing the content of hardeners introduced. Based on complex studies, it is shown that the developed polymeric adhesive should be used in the restoration of marine transport units, in particular, wheel fit in the compressor section of turbocharger.

“…Titanium alloy is also used in marine engineering as a corrosionresistant and lightweight structural material (propeller, bathyscaph, etc.) [13,14]. In addition, non-toxic, non-magnetic, and better biocompatibility make titanium alloy widely used in medical implants (joint prosthesis, skeletal repair, etc.)…”

Titanium Alloys - Recent Progress in Design, Processing, Characterization, and Applications

View full text Add to dashboard Cite

The titanium industry has been developing for nearly 70 years since the birth of Ti-6Al-4 V alloy. Due to its high specific strength, high and low-temperature resistance, corrosion resistance and good biocompatibility, titanium alloy is used in aerospace, marine engineering, and biomedical fields. However, the high production cost of titanium alloys currently limits their widespread use like steel and aluminum alloys. Therefore, the low-cost preparation technology for titanium alloys becomes hot research in recent years. This chapter provides a comprehensive overview of low-cost preparation technologies for titanium alloys from four aspects: raw materials, melting, hot working and machining, and advanced technologies. This review would be of interest to scholars in related fields.

“…AISI 904L is now one of the most common grades of this high-strength austenitic stainless steel (HSASS) [16] following its applications in energy [22,23], petrochemical [24,25] and marine sectors [26,27]. In particular, it is widely adopted in synthetic biomass ash environments [22], in oil and gas transportation [28] and in components employed in seawater environments [29,30].…”

AISI 904L is a super-austenitic stainless steel that is remarkable for its mechanical properties and high corrosion resistance, which strictly depend on its chemical composition and microstructural features. The recrystallization process and grain growth phenomena play key roles in achieving high levels of material quality, as often requested by customers for specific applications. In this paper, the evolution of the microstructure and hardness values after cold rolling and subsequent annealing is reported, with the aim of optimizing the thermomechanical treatment conditions and improving the efficiency of the production process. The investigation was focused on three different cold reduction ratios (50%, 70% and 80%), while combining different annealing temperatures (950, 1050 and 1150 °C) and soaking times (in the range of 20–180 s. The test results were organized using a data analysis and statistical tool, which was able to show the correlation between the different variables and the impacts of these on recrystallization and grain growth processes. For low treatment temperatures, the tested soaking times led to partial recrystallization, making this condition industrially unattractive. Instead, for the higher temperature, full recrystallization was achieved over a short time (20–40 s), depending on the reduction ratio. Regarding the grain growth behavior, it was found to be independent of the reduction ratio; for each treatment temperature, the grain growth showed a linear trend as a function of the soaking time only. Moreover, the static recrystallization kinetics were analyzed using a statistical analysis software program that was able to provide evidence indicating the most and least influential parameters in the process. In particular, taking into consideration the hardness values as output data, the temperature and soaking time were revealed to have major effects as compared with the reduction ratio, which was excluded from the statistical analysis. The prediction approach allowed us to formulate a regression equation in order to correlate the response and terms. Moreover, a response optimizer was used to predict the best solution to get as close as possible to the hardness target required by the market.
