Abstract

<B>APARELHO DE TESTE E MéTODO PARA MEDIR A REISTêNCIA à CORROSãO DE FILME OU REVESTIMENTO<D> A presente invenção refere-se a um aparelho de teste e procedimento utilizado para a caracterização quantitativa e qualitativa de comportamento contra corrosão e arranhões de filmes ou revestimentos, mais particularmente revestimentos automotivos. O aparelho inclui um microcortador que penetra e arranha o revestimento a ser caracterizado juntamente com componentes inter-relacionados para a medição da força aplicada, do comprimento e profundidade de penetração do cortador, da geometria da superfície de revestimento agitada, bem como meios para a medição, análise e comparação dos resultados de teste.
