Hydrogen Fluoride Ion Cleaning Nozzles

This solicitation (N68520-25-SIMACQ-JC00000-0397) seeks a contractor to perform Hydrogen Fluoride (HF) ion cleaning of T64 stage 3 turbine nozzles and F404 turbine nozzle segments. The cleaning process must achieve a continuous denuded surface layer between 0.0005 and 0.001 inches deep, with intermittent denudation up to 0.003 inches deep, free from yttrium, titanium, and aluminum. No continuous intergranular attack of carbide phases is acceptable, though non-continuous attack up to 0.003 inches deep is permissible below the denuded layer. Post-cleaning surface oxidation requires grit blasting and reprocessing. Return shipment must not exceed 10 business days (20 days for additional cycles). Packaging and shipping must conform to ASTM-D-3951. The contract includes specific NSN and part numbers for the nozzles to be serviced (listed in sections 5.1 and 5.2 of the attached Statement of Work). The contract is a firm fixed price, with an 8-month base period and 12-month option periods. Offers will be evaluated based on technical solutions addressing paragraphs 4.1 and 4.2 of the Statement of Work, and price, with the total price for all options added to the base requirement price. Offers must be submitted to jeffrey.t.smith6.civ@us.navy.mil by 25 September 2025 at 5:00 PM local time.
