1.1 Scope. This specification covers requirements intended for use in the procurement of powders used to produce deposits utilizing a cold spray materials deposition process for the purpose of parts repair, coatings, or fabrication of near-net shaped parts. 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 thin coatings, thick deposits, or near-net shaped parts. This cold spray process is explained in the manufacturing process standard MIL-STD-3021, "Materials Deposition, Cold Spray". The base document of MIL-DTL-32495 contained requirements for Aluminum powders only. This new Revision (A) expands the list of powders to include additional materials beyond aluminum."
