Abstract
Provided is a well system, and a method. The well system, in one aspect, includes a wellbore positioned within a subterranean formation, as well as a downhole tool positioned within the wellbore. The downhole tool, according to one aspect, includes a housing, as well as an expandable metal member positioned about the housing, the expandable metal member comprising a metal configured to expand in response to hydrolysis. The well system, in one further aspect, includes a reactive colloidal dispersion of colloid particles surrounding a surface of the expandable metal member.
