Effective mitig<strong>at</strong>ion time – effect <strong>of</strong> τ char<br />

The chemical erosion<br />

from beginning to<br />

s<strong>at</strong>ur<strong>at</strong>ion can be fitted<br />

as<br />

τ mit - effective<br />

mitig<strong>at</strong>ion time<br />

In a certain range τ mit is <strong>linear</strong> dependent on τ char . . .<br />

Any assumption for τ char e.g. dependence on T surf will<br />

be reproduced by τ mit .<br />
