In this study, martensitic stainless steel (MSS) powder was combined with glass powder (GP) and Portland limestone cement (PLC) at concentrations of 5, 15, and 25 wt.% to evaluate their structural, electrochemical, and thermal properties. X-ray diffraction analysis indicated that diopside and cristobalite phases were dominated in the MSS-25GP sample, while alite and belite phases were prevalent in MSS-25PLC. The MSS control sample exhibited the highest polarization resistance (1810 Ω), indicating superior corrosion resistance compared to the composite samples, with MSS-15GP (336.4 Ω) and MSS-15PLC (226.7 Ω) showing significantly lower values. The corrosion potential (Ecorr) of the composite samples shifted to more negative values, with MSS-25GP showing Ecorr = − 886.0 mV, much lower than the control sample at Ecorr = − 547.0 mV, reflecting a higher susceptibility to corrosion. The presence of GP and PLC additives led to a hindered anodic reaction, as evidenced by the elevated anodic Tafel slope (βa = 865.3 mV dec-1 for MSS-25GP), compared to the MSS control sample (βa = 111.1 mV dec-1), suggesting a reduction in the anodic corrosion rate. The maximum hardness was achieved in the MSS-25PLC sample at 166.17 N/mm2, while the highest bulk density was measured in MSS-5PLC at 5.692 g/cm3. Maximum specific heat capacity values obtained on the MSS-15GP and MSS-5PLC composite samples as 4.81 and 4.70 J/g °C, respectively, at 85 °C temperature. These results indicate that the incorporation of GP and PLC effectively tailors the microstructure and functional properties of MSS composites, enabling their potential use in both structural components and thermal energy storage systems.
