Metallic Coating Standards

    ASTM's metallic coating standards are instrumental in the evaluation and examination of the physical, chemical, mechanical, and metallurgical properties of metallic powders intended for use as coating material. These standards help to identify characteristics such as density, particle size, compressibility, rupture strength, and surface finish among others. Also, these metallic coating standards allow powder metallurgy laboratories, and other companies that deal with metallic powder coatings to appropriately test them for the chemical and mechanical qualities to which they should conform.
