Ardrox®
188 is an alkaline powder blend containing an oxidising material whilst Ardrox®
188RFU (Ready For Use) is a liquid version of Ardrox®
188 powder. It is primarily intended as an
aid in removing difficult heat scale such as those produced on high chromium steels and nickel
and cobalt alloys, which are notoriously difficult to remove even with strong acids. Ardrox®
188RFU or Ardrox®
188 will not normally remove such scales by itself, but will chemically and
physically modify them in such a manner as to make them more easily removable by milder and
less dangerous methods than the use of strong acids.
The main field of use for Ardrox®
188RFU or Ardrox®
188 is the overhaul of "hot end"
components of gas turbine engines. Ardrox®
188RFU and Ardrox®
188 have also been found
useful for the removal of adherent carbon smut produced after heat treatment.
