Abstract

"PEçA DE CONTATO DE VOLFRáMIO COM UMA CAMADA INIBIDORA DE CORROSãO FEITA DE ESTANHO". Objeto da invenção é uma peça de contato abrangendo uma base de volfrâmio soldada sobre um suporte, em que ao menos partes da camada de solda e eventualmente do suporte estão recobertas com uma camada de um metal menos nobre do que volfrâmio. Graças à invenção é consideravelmente aperfeiçoada a resistência à corrosão da base de volfrâmio.
