Abstract
Provided are a downhole tool, a well system, and a method. The downhole tool, in 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 downhole tool, according to one aspect, further includes colloid particles surrounding a surface of the expandable metal member.

A well system, comprising:
- a wellbore positioned within a subterranean formation;
- a downhole tool positioned within the wellbore, the downhole tool including:
- a housing;
- an expandable metal member positioned about the housing, the expandable metal member comprising a metal configured to expand in response to hydrolysis;
- and
- colloid particles surrounding a surface of the expandable metal member.

A method, comprising:
- positioning a downhole tool within a wellbore of a subterranean formation, the downhole tool including:
- a housing;
- an expandable metal member positioned about the housing, the expandable metal member comprising a metal configured to expand in response to hydrolysis;
- and
- colloid particles surrounding a surface of the expandable metal member;
- subjecting the expandable metal member to a reactive fluid while in the presence of the colloid particles, thereby forming an expanded metal member having the colloid particles in interstitial spaces thereof.
