Test for verify the passivation of components in Aluminum bronze

  • 1.  Test for verify the passivation of components in Aluminum bronze

    Posted 2 hours ago

    Good Morning

    I'm a AMPP member n.580543. Currently  work in a Nuclear project , and we have a problem to verify if some Aluminium bronze components are passivation or not or partially. The componets was pickling and passivated by process using suggest reagents by the supplier . But after the process a wype test was apply with negative results ( stain of yellow colour ). There it is some specific and definitive test ot method to verified if the component are fully pasivated or not ( as for the stainless steel )?
    Thank and best regards
