LSP™ Chemical Stripping of Coatings

To enable high sensitivity inspection of parts, protective coatings must be removed from hot section components, turbine blades and vanes.

This is accomplished through chemical stripping processes which are custom designed by each service company — and therefore have varying effectiveness for removing each coating type.

The Liburdi LSP™ process is highly effective for all coating types used by the industry — Aluminides, Platinum Aluminides, MCrAlYs and therefore avoids the need for abrasive coating removal practised by some service providers.

Unique to the Liburdi process is the ability to chemically remove oxides and coatings from internal cooling passages, and thereby enable the application of new internal coatings as part of the extended life repair.
