摘要

Improvements in the elements for coating of galleries, in which the sliding surfaces of the reciprocally displaceable parts have a layer or cover of zn or a zinc alloy, characterized in that the zinc-containing cover provides a paint which, reacting with the zinc, originates non-oxidizing combinations and thus produces a passivation of the zinc layer.
