本规范涵盖了由化学转化材料与铝及铝合金表面反应形成的两类化学转化涂层的要求。本规范旨在为军事武器系统的部件提供最大的耐腐蚀性。该涂层还提供了比未涂层铝具有更好的油漆附着力的表面。它不是用于商业和装饰应用的通用涂料。

This specification covers the requirements for two classes of chemical conversion coatings formed by the reaction of chemical conversion materials and the surfaces of aluminum and aluminum alloys. This specification is intended specifically to provide components of military weapon systems with maximum corrosion resistance. The coating also provides a surface having better paint adhesion than uncoated aluminum. It is not intended as a general purpose coating for commercial and decorative applications.
