Wettability control of modified stainless steel surfaces for oxide catalyst carrier slurry coating

Micrometer sized FeAl particles were added on 304 stainless steel surfaces to prepare rough surfaces with irregular patterns to make the surface super hydrophilic in order to effectively coat catalyst carrier alumina slurry on them. This method was compared with other conventional methods as follows. Micromachining and acid etching were firstly tried to prepare regular patterned surfaces with square micropillar arrays. Sand blasting was then...
