To address such design and repair issues, the ONR's Sea-Based Aviation team initiated a project to introduce modern practices into corrosion design, and ultimately combine computational methods such as CA E and f inite element analysis (FEA) to model galvanic corro- sion. The aim of the project is to be able to predict galvanic corrosion between dif- ferent materials, coatings, and treat- ments. Key to the project is a new elec - trochemical database of qualif ied polarization curves for various materials. Additionally, the software tool was devel- oped to use these polarization curves to calculate galvanic corrosion currents and corrosion rates. Galvanic corrosion inside the wing of an F/A-18 Hornet.

N AC E A n n u a l C a r e e r a n d S a l a r y S u r vey C o m i n g S o o n MP Announces April Mailing of 2017 Survey Questionnaire We encourage all invited members to participate this year Within the next few weeks, a link to the questionnaire for NACE International's annual corrosion career and salary survey will be emailed to NACE members in the United States, Canada, and Europe. We ask that you please watch your inbox for this valuable survey from mpsalarysurvey@nace.org and fill out your questionnaire. It will only take a few minutes of your time, and the more responses we receive, the better the results will represent the state of the industry. The results will be reported in the July 2017 issue of Materials Performance (MP) magazine. As in the previous two years, the online survey will again be conducted by an independent survey company and all responses will be completely anonymous. If a survey questionnaire link is emailed to you, we urge you please take a few moments to fill out the form and submit it.
