Thisstandard is issued by the Accredited Standards Committee B3 of theAmerican National Standards Institute as an industrial standard that isintended to be used by aircraft manufacturers, or aircraft engine manufac-turers, or both, for the procurement of rolling element bea

17、esegrinding processes can cause excessive local-ized heating of the metal being worked andresult in altering the metallurgical structure ofthe alloy. An inspection method of etching theground surface of these alloys with acids per-mits detection of those altered structures. Thisspecification for tem

19、nd another ofwater base, in addition to use of a photo-graphic gray scale to control bath immersiontimes and part etching levels.
