[29], the compressive stress will lead to a microplastic deformation to the faying surface. Due to the protruding SiC particles on the surface of the composites, the microplastic deformation is higher with the asperities.
Owing to presence of Fe content in solid solution of solder we can consider that erosion of the faying surface of cast iron is concerned.
In addition, because of the relatively low surface temperatures and thickness of the parts it is assumed that radiation and convection losses at the part surfaces are negligible; because of the low transmission of the far IR radiation generated by the heating of the faying surface, any IR losses at the faying surface are assumed to be negligible.
* 10 m[ohm] or less from the equipment enclosure to the system structure including the cumulative effect of all faying surface interfaces.
Caption: Thomas visually inspects his work to ensure proper bonding of the rib's faying surfaces. Heat lamps are placed on both sides of the aircraft to accelerate curing.
Heat produced by the Eire melts the base material as the electrode moves around the joint, progressively melting and fusing the faying surfaces. Inert shielding gases fed externally and internally form an ideal welding environment.
To protect the blade bolts, the faying surfaces of the blade and the grip, apply some corrosion preventive compound (CPC), NSN 8030-00-244-1297, like it says in WP 5-1-5 of TM 1-1520-248-23.
Thin coatings of Ni or Cu interlayers [7] on the faying surfaces of TiC-based cermets can protect the surfaces and improve wetting.
Commonly, the mechanical strength of faying surfaces is not so strong that the composites can be destroyed easily.
Bonding of faying surfaces should be via bare metal-to-metal contact of similar materials fastened by, in order of preference, welding/soldering, riveting, or bolting.
