| Abstract: |
The electrostatic spraying method was used in this work to create a composite mixture of NiO and Ag with PMMA powder as a binder and to combine several dry powders. The electrostatic spraying method applied the powder mixture at a high voltage of 15 kV to a 316L stainless steel substrate with dimensions of (20 x 20 x 2) mm. The analysis was performed on the effects of the percentages of Ag and NiO in the PMMA matrix on the surface properties of 316L stainless steel substrate. Accurate measurements of the hardness of the coating layer and the contact angle showed that it was successfully fabricated to be uniform throughout and free of fractures, as the chemical content and structure of the composite coatings were examined by XRD, FESEM, and EDS. The roughness values were also increased because the surface layers of the composites made are smooth and have good molecular dispersion. It was found that the average thickness of the coating for the composite coating is 67.56 um for a percentage of 4% NiO, 69.2 um for 6% NiO, and 71.5 um for 8% NiO. [ABSTRACT FROM AUTHOR] |
