Summary:

This paper compares several different test methods used to test maintenance chemicals for potential to induce hydrogen embrittlement in high-strength steel. The program was structured to accomplish three main objectives with regard to hydrogen embrittlement testing: 1) compare various test methods used to qualify maintenance chemicals, 2) compare various coatings used to protect high-strength steel parts such as landing gear, and 3) compare various high-strength steel substrates specified for aircraft landing gear. The coatings selected included electrodeposited cadmium (baseline), ion vapor deposited (IVD) aluminum, SermeTel 984, and Zinc-Nickel plate. Substrates tested included AISI 4340 (260-280 ksi HT), 300M (280-300 ksi HT), and AerMet 100 (minimum 290 ksi HT)
