Valence Everett Obtains Range Rare Lockheed Martin Approvals
Valence Everett (Everett, Wash.) has further diversified its surface treatment capabilities in the Pacific Northwest with the approval of critical Lockheed Martin Aeronautics (Bethesda, Md.) processes that support the F-35 Joint Strike Fighter. Valence would particularly like to highlight the addition and approval of its environmentally friendly Thin Film Sulfuric Anodize process. Thin Film Sulfuric Anodize is a non-hexavalent chromium substitution for the more traditional Chromic Acid Anodize. This approval makes Valence Everett only the fourth Lockheed Martin-approved Thin Film Sulfuric Anodize processor in the world. These comprehensive new approvals allow Valence Everett to support the special processing of fracture-critical structural components, including bulkheads.
Valence Everett is now offering the following Lockheed Martin processes and approvals:
- Penetrant Inspection - MIL-STD-6866/ASTM-E-1417; LM Process Code 110A
- Penetrant (Fluorescent) Inspection - LMA-PC201; LM Process Code 113
- Penetrant Inspection Fracture Critical - LMA-PC201; LM Process Code 113a
- Pre-Penetrant Etch-Aluminum - LMA-PG001; LM Process Code 148
- Conductivity Testing - LMA-PC009; LM Process Code 167
- Conductivity of Aluminum - ASTM-E-1004; LM Process Code 174
- Non-Chromic Acid Anodize - MIL-A-8625, Type 1C, see 5PTPHL23/5PTPHB20, LMA-PH090, FPS3090; LM Process Code 200A1
- Thin Film Sulfuric Anodize - LMA-PH090; LM Process Code 200V
- Chem Film - AMS-C-5541/MIL-DTL-5541, Type I, Class 1A and Class 3; LM Process Code 210
- Application and Control of Organics Finishes - LMA-PJ264; LM Process Code 240C
- Fuel Tank Coating - MIL-C-27725/AMS-C-27725; LM Process Code 242A

The first-tier aerospace powder coating supplier recently had its MIL-SPEC powder coatings qualified for coating power supplies for a classified military satellite program.
Solvent substitution for maintenance and overhaul operations of military systems has been a primary environmental concern for many years. Cadmium replacement in these systems has been targeted for decades. Both of these areas have a common obstacle for implementation of any potential alternate. Hydrogen embrittlement of high strength steel is the most predominant unforeseen hurdle since high strength materials show sensitivity to the phenomena and the source of the hydrogen can be anything within the fabrication process, maintenance practice or the natural corrosion cycle. Standardized testing on this issue has traditionally stemmed from the aerospace industry where it is a principal focus.
