Pickled, plated, etched (to remove white layer), or electrolytically cleaned or stripped parts shall be baked to remove hydrogen as specified in AMS2759/9. Where pickling or electrolytic cleaning is performed as an integral part of a plating operation, baking is not required after each process but shall be performed following the final process provided not more than 4 hours elapse between such operations.
The depth shall meet the requirements of the engineering drawing. If the engineering drawing and/or purchase order specifies a case depth but does not specifically state that it is to be an effective case depth, total case depth, as defined below, shall apply. In cases where the engineering drawing or purchase order specifies post nitride surface removal (see ordering information), the reported case depth shall include the amount to be removed.
The total case depth shall be the depth of the continuous etching subsurface zone, determined metallographically from a section of the as-nitrided part or a control specimen prior to machining, or may be determined by a microindentation hardness traverse conducted in accordance with ASTM E384. On those alloys which do not respond by darker etching, the total case depth shall be the depth below the surface at which the hardness is 50 HK or 50 HV higher than the core below the nitride case, as determined by a Knoop or a Vickers hardness traverse respectively. The average of a minimum of three hardness readings taken at a minimum distance of 2X the case depth shall be used to determine the core hardness below the case.
When required (see ordering information), the effective case depth shall be as specified. It shall be the as nitrided case depth at which the values specified in Table 1, converted from microindentation hardness, are obtained by performing a hardness traverse in accordance with ASTM E384. In cases where the engineering drawing or purchase order specifies post nitride surface removal (see ordering information), the reported effective case depth shall include the amount to be removed.SAE AS 13001A pdf free download.
