Approved for public release; distribution is unlimited.COMMERCIAL ITEM DESCRIPTIONPHOSPHATE COATING COMPOUNDS, MANGANESE OR ZINC BASE(FOR FERROUS METALS)The General Services Administration has authorized the use

3、of thiscommercial item description as a replacement for MIL-P-50002B forall federal agencies.1. SCOPE. This commercial item description (CID) covers both manganese and zinc basephosphate coating compounds to be used in the preparation of bath for “heavy“ phosphate coatingof ferrous metal parts and a

4、ssemblies.2. CLASSIFICATION. Phosphate coating compounds shall be of the following types(see 7.5(b).Type M - Manganese base phosphateType Z - Zinc base phosphate3. SALIENT CHARACTERISTICS3.1 General. The phosphate coating compound shall be a uniform liquid, free of sediments andsuspended particles,

5、and shall be capable of producing uniform and insoluble coating that is grayto black in color.3.2 Composition. The phosphate coating compound shall consist of balanced aqueousphosphoric acid solutions of manganese and zinc phosphates, and nitrate accelerator. Whendetermined in accordance with the ma

6、nufacturers standard test methods, the compound shallconform to the chemical requirements specified in table I.Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-A-A-592672Table I.

When it is necessary to express the coating weight in mg/ft2,the following conversion calculations shall be used.mg/ft2 = (g/m2) (1000 mg/g) / (10

10、.764 ft2/m2)3.4 Corrosion resistance. The phosphate coating compound shall provide corrosion resistancesuch that bare phosphate coating (without any supplementary treatment) on parts, shall show nosigns of corrosion when subjected to a 5 % salt spray (fog) test as described in ASTM B117,“Standard Pr

11、actice for Operating Salt Spray (Fog) Apparatus“. The period of exposure to saltspray test shall be 1.5 hours for Type M products and 2.0 hours for Type Z products.3.5 Bath operation and controls. The bath concentration, operating temperatures, and immersiontime for parts shall be designated by the

12、manufacturer. Control of the chemical content of thephosphate coating solution in bath shall consist of determination of free acid, total acid, andferrous iron and shall be verified in conformance with the manufacturers instructions.3.6 Metal surface treatments. All metal preparation treatments and
