Senior Metallurgical Materials Engineer

Overview

The United States Coast Guard (USCG), Aviation Logistics Center (ALC) provides centralized logistics support for all USCG aviation missions. As the sole industrial complex for USCG aviation, ALC provides: depot level maintenance, engineering, supply, procurement, acquisition and information services. ALC's mission supports twenty six (26) USCG aviation units that operate approximately two hundred (200) aircraft. These air stations are located throughout the continental United States, Alaska, Hawaii, and Puerto Rico. ALC also currently provides depot-level maintenance to both USCG and other Government aircraft. Scientific, Engineering, and Technical (SET) Services are required to support the mission of ALC in various engineering and technical service cells throughout the ALC.

ISHPI's team of scientists and engineers will support the airworthiness and sustainment of Government aircraft and equipment by developing and providing solutions to mitigate and prevent processes that affect the aircraft life cycle. Ishpi's team will perform, implement, and support engineering and scientific activity such as, but not limited to, root cause failure analysis, sample preparation, testing, training, data analysis, re-engineering, and engineering analysis for aircraft structure, components, and systems

Responsibilities

The Senior Materials Engineer will conduct materials engineering, corrosion engineering, materials science, and failure analysis required to support Government aviation. This includes, but is not limited to the following tasks:

  • Perform root cause failure analysis:
    • Utilize a three phase (collection, analysis, and a conclusion) root cause failure analysis process
    • Include background information, failed components, new components, collection of residues, images, environmental conditions, component history reports, aircraft history reports, personal testimony of maintenance staff or operators, non-destructive inspection and mechanical testing
    • Perform sample collection IAW ASTM Ell88-ll, Standard Practice for Collection and Preservation of Information and Physical Items by a Technical Investigator

    • Characterize striations -Fractography should follow the techniques described in ASTM STP645, Fractography in Failure Analysis
  • Assist in and design of experiments and perform experiments to determine component life predictions, material substitution, new materials, coatings, and corrosion prevention compounds following terms and definitions described in ASTM E1325-02, Standard Terminology Relating to Design of Experiments
  • Support organic and inorganic coating protection initiatives:
    • Provide materials engineering consultation with regards to industry and DOD coating specifications
    • Test coatings to ensure they meet respective specifications
    • Review coatings test results
    • Measure color, gloss, and coatings thicknesses using color spectrometers and thickness gauges
    • Quantify coating performance results using visual or microscopic methods following the guidelines described in ASTM E1808-96, Standard Guide for Designing and Conducting Visual Experiments
  • Identify alloy using energy dispersive spectroscopy and X-ray fluorescence spectroscopy:
    • Include results by atomic weight percent and a comparison to the alloy standard
    • Address and explain variations between the results and the standard follow the guidelines of ASTM E1508-12a, Standard Guide for Quantitative Analysis by Energy-Dispersive Spectroscopy
  • Operate various microscopes to include light microscope, optical microscope, inverted microscope, digital microscope, and scanning electron microscope:
    • Acquire forms of images that a microscope can provide, such as a secondary electron image, a backscatter electron image, a 3-dimensional image, and a 2-dimensional layer image
    • Apply technical capabilities of the microscopic equipment for imaging, measuring and analysis following guidelines outlined in ASTM E1951-14 Standard Guide for Calibrating Reticles and Light Microscope Magnifications, ASTM E986-04 Standard Practice for Scanning Electron Microscope Beam Size Characterization and ASTM E766-14 Standard Practice for Calibrating the Magnification of a Scanning Electron Microscope
