Abstract
The mechanism of electroless deposition of lead and zinc and their codeposition on an aluminum substrate in a chloride electrolyte melt at temperatures below the melting point of aluminum has been studied. It is shown that lead forms a dense thick (up to 60 μm) porousless layer on aluminum during the contact exchange, whereas zinc coatings are not more than 30 μm thick and have a number of pores a few nm to 1 μm in diameter penetrating to the aluminum substrate. When lead and zinc are deposited simultaneously, the whole aluminum surface is covered with a two-phase coating lead precipitates as round spots with zinc between them; areas with deposited lead are free of zinc and vice versa.
