Slip elements for a bridge plug include an inner body portion that is substantially formed of a material that is degradable by dissolution in response to a dissolving fluid and a hardened, resilient, radially outer contact portion. The outer contact portion includes a plurality of openings that function as stress risers. The inner body portion may be formed of magnesium powder.
