Abstract

Deposition of the MAX phase compound Ti₃SiC₂ onto stainless steel substrate using the sheet plasma negative ion source (SPNIS) was investigated through the calculation of surface energy. An optical microscope was used to measure contact angles of static liquid drops onto the samples and the van Oss-Chaudhury-Good method was employed to calculate the surface energy. Three samples were prepared with differing CH₄:Ar ratios of 1:4, 1:5 and 1:8. Results showed that Ti₃SiC₂ deposit increased the hydrophobicity of the stainless steel. As the ratio of the gases increased, the substrate became more hydrophobic. The sample with 1:4 gases ratio displayed high hydrophobicity with a maximum static water contact angle of 100.070. Finally, the surface energy of the MAX-phase coated stainless steel was noticeably decreased compared to the uncoated surface.
