Evaluation of the Hughes Conversion Coating Touch-Up Pen

摘要

Chromate conversion coatings are common surface pretreatments for aluminumsubstrates on Navy aircraft, weapon platforms and ground support equipment. While this chromated process performs satisfactorily, future restrictions require the elimination or minimization of chromium emissions from this process. One approach to minimize emissions is through the incorporation of new touch-up procedures. A chemical film Touch-Up Pen developed by Hughes Ground Systems Group offers potential to provide the required paint adhesion and corrosion protection for aluminum for repair applications. The Naval Air Warfare Center Aircraft Division at Warminster performed a study of this pen and the following is a description of the evaluation.
