The Department of Defense tri-service/industry Hard Chrome Alternatives Team (HCAT) and Joint Group on Pollution Prevention (JGPP) are collaborating on executing a program to qualify HVOF thermal spray coatings as a replacement for hard chrome plating in the manufacturing and repair of aircraft landing gear. The Canadian Department of National Defence and Industry Canada are also partners in this effort. A joint test protocol (JTP) has been prepared and approved by the stakeholder organizations, including OEMs and government organizations. Included in the JTP are material tests such as fatigue, wear, corrosion, hydrogen embrittlement and impact, and operational tests on actual components. Results will be presented for a substantial amount of the material testing as well as the results of a rig test on the Navy F/A- 18 E/F main landing gear containing several HVOF-coated components and the status of flight testing on Navy P3 and E-6A aircraft containing HVOF-coated landing gear components.
