All details of workmanship shall conform to the best practices for high quality coating.

Unless otherwise specified, minimum thickness of the nickel coating shall be 0. Heat treated to obtain required hardness: The separate specimens shall be strips approximately 1-inch wide, 4-inches long, and 0.

Aluminum 266074, heat-treatable, processed to improve adhesion of the nickel deposit.

Any part numbers established by the original specification remain unchanged. It is encouraged that recycled material be used when practical as long as it meets the requirements of the document see 3. Thanks so much for asking, Ed: The use of this report is entirely voluntary, and its applicability and suitability for any particular use, including any patent infringement arising therefrom, is the sole responsibility of the user. The nickel coatings shall be classified in accordance with the thermal treatment applied subsequent to plating.

SAE invites your written comments and suggestions. It also shall be impossible to detach any area am the coating with a sharp instrument on the outside radius amx the bent-test specimen. The Aerospace Materials Division, however, does not recommend these specifications for future use in new designs. Title, number and date of the specification. Unless otherwise specified, the shot peening shall be accomplished on all surfaces for which the coating is required and all immediately adjacent surfaces when they contain notches, fillets or other abrupt changes of section size where stresses will be concentrated.



Samples shall be selected from each lot see 4. I hope you find this information helpful! A lot shall consist of coated parts of the same type and class, same basis material, and of approximately the same size and shape, coated under the same conditions and by means of the same coating process, and submitted for acceptance at one time.

Unfortunately, the MIL-C was not cancelled at that point xms time.

The nickel coating shall be smooth, adherent, and free from visible blisters, pits, nodules, porosity, cracks and other defects. When tested in accordance with 4. Unless otherwise specified, all inspections shall be performed in accordance with the methods of inspection specified in 4. This specification covers the requirements for electroless autocatalytic chemical reduction deposition of nickel-phosphorous alloy coatings on metal and composite surfaces.

Still SAE felt that the specification duplicated pre-existing standards and wanted to withdraw the document in favor of those older and well-used documents. Number of this specification.


Hydrogen embrittlement relief bake: Failure of one or more of the test specimens shall constitute failure of cc lot. Each part, or specimen shall be tested as specified in 4.

Class and grade, and heat treatment or condition see 1. Our drawing states to process parts to MIL-C Unless otherwise specified in the am or purchase order, the contractor is responsible for the performance of all inspection requirements examinations and tests as specified herein. Your email address will not be published. Sampling plan B – Sampling procedures for evaluating hydrogen embrittlement relief destructive test – Class 1 and 2: Equipment, solutions, and process procedures shall be subject to the approval of the procuring activity.

Iron, copper, aluminum, nickel, ame, beryllium, titanium, and their alloys can be plated directly.

Sampling plan C – Sampling procedure for adhesion tests: Coated parts of stainless steel similarly facilitate brazing. If the number of parts in an inspection lot is 15 or less, the number of parts in the sample shall be 2 or 3 as determined by the procuring activity.
