Studium transparentních nanopovlaků pro aplikaci na ocelový substrát

Abstract

The theoretical part provides basic information on evaluation of surface materials, organic coating properties and pigment properties in micro- and nanoscale. The experimental part focuses on the comparison of the results of surface samples of wrought pipes and brushed sheet metal Standard. The surfaces of these samples were coated with transparent anticorrosive varnish based on alkyd resins in two different ways – by a brush and by air spraying. The coating system was mixed with anticorrosive pigment “zinc phosphate ZP10”, containing particles in the nano-size of 3-5% and 6-9%. Samples with applied coating systems were subjected to a cross hatch test of adhesion and to a corrosion test. The results were then recorded and analyzed.
