Materials with Shape Memory Effect for Applications in Maritime

Abstract

In this review it is presented the insight of challenges faced by all branches of industry in the new age, and especially the maritime industry, strive for sustainable development, better energy control, use of materials with functional properties such as shape memory, all in the direction of increasing safety and comfort. Therefore, the development of new materials with shape memory, which is associated with the introduction of optimized production and the achievement of better functional properties. This leads to new applications in different systems and possible use on devices, which meet the rigorous requirements of the modern industry. The research into new materials with shape memory effect and their applied use in maritime is a challenge that many researchers have encountered in recent decades, and this is why in this paper we look at the basic engineering aspect of these materials and their current as well as future applications in the maritime industry. An overview of several innovations that testify shape memory effect and superelasticity in different maritime fields will be presented in this review.

Statistical Methods Applied in Modeling Corrosion Depth Measurement on Three Different Shape Memory Alloys

“…In this way, a total of six models were formed, which are shown by the expressions given in Eqs. ( 6)- (11). The formed six models shown through Eqs.…”

“…The sea models (Eqs. ( 5), (8), and (11)) underscore the aggressive nature of Statistical Methods Applied in Modeling Corrosion Depth Measurement on Three Different… DOI: http://dx.doi.org/10.5772/intechopen.1005179 the marine environment, with a notable impact of both time and oxygen on corrosion for all alloys. The interaction term's effect suggests complex dynamics between exposure time and oxygen concentration in driving corrosion in sea conditions.…”

“…While SMAs are less commonly used in marine and maritime sectors compared to medicine and transportation, their potential applications range from deep-sea tube connections to surface-level technologies, thanks to their superelastic properties. SMAs offer solutions for tension-leg platforms, subsea equipment thermostats, and thermal energy transfer in undersea power plants [11]. Their suitability depends on mechanical, chemical, physical, and thermo-mechanical traits, particularly corrosion resistance.…”

Dynamic mechanical damping analysis of up/step-quenched Cu-Zn-Sn-based shape memory alloys

“…Cu-Zn-Sn-based SMAs are continually being used in numerous industrial applications such as in heat exchanger tubing [35] as well as hydraulic fittings, connector pipes, valves and pumps [36]. The majority of these areas of applications expose them to vibrations and mechanical shocks.…”

The Analyses of the Corrosion Process of a NI-Ti Shape Memory Alloy in Different Environment

“…Unlike other industries such as aviation, the automotive industry and medicine, in recent decade's research has been conducted with the aim of applying SMA in the maritime industry. It has been used so far in different type of ships, under water vehicles (manned and unmanned), and various marine structures as they are offshore applications or wind farm, change of bulb shape, pipe tightening, coupling, subsea devices, elements of thermostat, driven power plant, shell structure, can be find (Ivošević, Š. and Rudolf, R. 2018) (Huang W. 1998).…”
