This recommended practice describes the engineering requirements for producing a voltage-resistant, non-powdery anodic coating on titanium and titanium alloys and the properties of such coatings.
This Aerospace Recommended Practice is intended as a guide toward standard practices for the determination of surface cleanliness that are applicable to field operation. Some of these methods can also be used to determine quality assurance that a surface has been properly prepared and maintained. The instrumental methods are: Wettability, Surface Potential Difference (SPD), Ellipsometry, and Optically Stimulated Electron Emission (OSEE). Each instrument is described with respect to measurement techniques, limitations, and advantages and types of available instruments. Elementary theoretical principles and examples of the use of each instrument are also given.

This specification covers procedures and requirements for dry peening the surfaces of metals by impingement of metallic shot or glass beads for the purpose of increasing the fatigue strength and resistance to stress corrosion cracking by inducing residual compressive stresses in specified surfaces.

This specification covers the engineering requirements for selective (brush) electrodeposition of nickel and the properties of the deposit. This process has been used typically to provide moderate corrosion and oxidation resistance and dimensional build-up and restoration of parts which may operate in service up to 700 degrees F (371 degrees C), where low tensile stress in the deposit is required to avoid marked reduction of fatigue strength, but usage is not limited to such applications.
