The efficiency of multifunctional composite coatings consisting of an intermediate adhesive layer and a surface wear-resistant layer undergoing thermoelastic martensitic transformations (TMT) is discussed. Using the example of a propeller blade, it is shown that materials with TMT in the composition of the surface composition provide an effective response to external influences (an increase in the endurance limit in seawater by 30%, wear resistance by 3.0—3.2 times, cavitation resistance by 15—20 times as compared to the base) and adaptation to loading conditions, that contributes to an increase in the service life. Evaluation of the stress-strain state of a propeller with the composite coating Ni—TiNiZr—TiNiCo showed a decrease in stresses in the most dangerous zone and confirmed the expediency of using materials with TMF to improve reliability.

This paper is concerned with the application of fundamental thermodynamic theories in the analysis of thermoelastic martensitic transformations in shape memory alloys, with a particular reference to polycrystalline NiTi. The discussion is delivered in two parts. The first part presents a concise overview of the fundamental theories of thermodynamics of thermoelastic martensitic transformations established in the past 30 years. The second part focuses on the principles governing the application of the theories, interpretation of the thermodynamic parameters defined in the theories, experimental determination of the parameters, and some common misperceptions and unjustified assumptions in practice concerning these parameters.
