本规范涵盖了用于采购铝和铝基合金粉末的要求，这些粉末将用于利用冷喷涂材料沉积工艺生产沉积物，用于零件维修、涂层或独立结构的制造。冷喷涂是一种利用金属粉末颗粒通过在基材上的弹道冲击形成沉积物以生产涂层或独立结构的工艺。这种冷喷涂工艺在制造工艺标准MIL-STD-3021“冷喷涂材料沉积”中有说明。

This specification covers requirements intended for use in the procurement of aluminum and aluminum-based alloy powders that will be used to produce deposits utilizing a cold spray materials deposition process for the purpose of parts repair, coatings, or fabrication of freestanding structures. Cold spray is a process whereby metal powder particles are utilized to form a deposit by means of ballistic impingement upon a substrate in order to produce coatings or free-standing structures. This cold spray process is explained in the manufacturing process standard MIL-STD-3021, "Materials Deposition, Cold Spray".
