摘要：

In the present work, the influence of superhydrophobic (SHP) silane as well as silanized silica nanoparticle coating on various steel substrates such as modified 9Cr-1Mo and 304L, were examined using Kelvin probe force microscopy (KPFM) for the first time. The surface potential mapping results showed that the SHP coating on the 304L stainless steel substrate, exhibited a higher stability than the modified 9Cr-1Mo steel substrate, which was attributed to the presence of significant amounts of highly resistant Cr and Ni in 304LSS in addition to the silanized silica nanoparticles in the coating. Two scale roughness was observed from the topographic images of the two substrates. The water contact angle values were comparable between the two substrates indicating a similar SHP behavior of the samples.
