Summary: This study investigates the effect of various factors on the bond strength of hydroxyapatite coatings on 316L Stainless Steel substrates. The results show that the bond strength is influenced by sonication temperature, time, and acetone concentration. The highest bond strength is achieved at a sonication temperature of 45 °C, time of 15 minutes, acetone concentration of 99%, and yields a bond strength of 91.35 Mpa.

Summary: The superhydrophobic effect is applied to the metal surface to improve its properties, attracting researchers' attention. ZnS superhydrophobic coating was successfully formed on 316L stainless steel surface after electrodeposition, solvothermal reaction, and chemical modification, showing excellent water contact angle and sliding angle. The coating exhibited self-cleaning property and stability, with 6 hours being the optimal solvothermal reaction time.

Summary: A superhydrophobic surface with excellent evaporation characteristics and anti-adhesion properties was fabricated by a simple chemical etching method. Compared to smooth surfaces, the superhydrophobic surface reduced the evaporation rate of lower concentration droplets and delayed the evaporation of higher concentration droplets. Additionally, the superhydrophobic surface effectively reduced the adhesion of high viscosity liquids.

Summary: The study found that the superhydrophobic coating on the 304L stainless steel substrate exhibited higher stability compared to the modified 9Cr-1Mo steel substrate, possibly due to the significant amounts of highly resistant Cr and Ni in 304LSS and the presence of silanized silica nanoparticles in the coating. The water contact angle values were similar between the two substrates, indicating similar superhydrophobic behavior of the samples.

Summary: The study successfully fabricated superhydrophobic coatings on the surface of 316L stainless steel samples through a one-step electrochemical process, with hierarchical micro/nanoscale structures and manganese stearate contributing to the superhydrophobicity and self-cleaning ability of the coating. The corrosion resistance of the 316L samples was also evaluated through Electrochemical Impedance Spectra in a seawater-mimicking aqueous solution after the electrodeposition process.

Summary: In this study, a robust surface with superhydrophobic properties was prepared on stainless steel mesh by electrodeposition combined with low surface energy modification method. The experimental results showed that the synergistic effect of dense petal-like micro-nano rough structures and stearic acid modification on the surface of the mesh endowed it with good superhydrophobicity and excellent performance.

Summary: This study investigates the formation behavior of Ni particles plasma sprayed onto AISI 1008 mild steel and 316 austenitic stainless steel substrates to compare the splat formation on both surfaces. Analytical techniques were used to analyze the characteristics of the splats formed on both substrates. Most of the observed splats were halo type splats driven by Rayleigh-Taylor instabilities. A linear relationship was found between the size of the splats' central core and their outer ring of debris, which was distinct for each substrate. Diffusion analysis showed a higher degree of diffusion across the interface between splat and stainless steel substrate, suggesting a better bond efficiency for stainless steel. Cross-sectional observations and theoretical calculations showed evidence of substrate melting and metallurgical bonds for both mild steel and stainless steel substrates.

Summary: The fabrication of super hydrophobic surfaces with various potential applications is possible through the combined adjustment of topography and chemical surface composition of stainless-steel. The usability of these surfaces depends on their chemical stability. In this study, a two-step modification process involving laser nanostructuring and chemical modification was used to create modified stainless steel surfaces. The temporal stability of the super hydrophobic properties of the surface was found to be dependent on the laser-induced surface topography.
