INSTRUMENTAL METHODS OF DETERMINING SURFACE CLEANLINESS

1995-05-01
HISTORICAL
ARP4252
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.

Impregnation of Porous Castings & Sintered Metal Components

2015-02-24
HISTORICAL
AMS03_1
This SAE Standard specifies the processes and type of impregnant which can be used when impregnating castings for the following purposes: a For the recovery of ferrous and non-ferrous castings containing micro porosity, where pressure tightness is mandatory. b For sealing castings/sinter metal components to improve corrosion resistance and/or to render the surface suitable for subsequent surface treatment.

Protection of Aluminum Alloys by Sprayed Metal Coatings

2015-04-27
HISTORICAL
AMS03_3
This SAE Standard specifies the requirements for the application of sprayed metal coatings of aluminum, zinc, or aluminum-zinc based alloys for the protection of aluminum alloys against corrosion. It does not cover the metal spraying of aluminumarmour materials, which should be treated in accordance with the requirements of Def Stan 08-39.
