Abstract

"PROCESSO E DISPOSITIVO PARA MEDIDA DE CARACTERìSTICAS DE UM REVESTIMENTO DE SUPERFìCIE DE PRODUTOS METALúRGICOS, EM LINHA". Para medir características de um revestimento de superfície (1) de uma tira metálica em passagem, tais como o nível de liga de um revestimento, comportando zinco e ferro, se expõe esse produto à radiação (23) de uma fonte radioativa (24) de comprimento de onda pré-determinado. A radiação é dirigida ortogonalmente à superfície do produto e mede-se a energia refletida por essa superfície, também segundo uma direção ortogonal à superfície, de forma a se livrar das variações de reflexividade, devido a características morfológicas da superfície e fazem-se operações com o auxílio de fibras ópticas comerciais previamente sem revestimento nas respectivas extremidades livres (21, 31) da respectiva fibra óptica de focalização habitual, de maneira a poderem ser aproximadas ao máximo uma da outra e dispostas paralelamente entre elas.
