摘要：
An open hemispherical pit in stainless steel is unstable because the concentration of dissolved cations must fall well below saturation near the rim of the pit, leading to passivation. Various pit morphologies including flask shapes and lacy metal covers are possible depending on the initial shape evolution and the critical chemistry required to stabilize dissolution in the pit.
