scope:

This specification covers two types of heavy phosphate coating for ferrous metals, applied by immersion. The coatings consist of a manganese phosphate or zinc phosphate base and, when specified, a supplementary treatment (see 6.1).

Coatings shall be of the following types and classes, as specified (see 6.2):

Type M Manganese phosphate base Class 1 Supplementary preservative treatment or coating, as specified Class 2 Supplementary treatment with lubricating oil conforming to MIL-L-3150 Class 3 No supplementary treatment Class 4 Chemically converted (may be dyed to color as specified). With no supplementary coating or supplementary coating as specified

Beneficial comments (recommendations, additions, deletions), and any pertinent data which may be of use in improving this document should be addressed to: Commanding Officer, Naval Ordnance Station, Standardization Division (611), Indian Head, MD 20640, by using the self-addressed Standardization Document Improvement Proposal (DD Form 1426) appearing at the end of this document or by letter.

Type Z Zinc phosphate base Class 1 Supplementary preservative treatment or coating, as specified Class 2 Supplementary treatment with preservative conforming to MIL-C-16173, Grade 1 or MIL-L-3150 (as alternate for very small parts Class 3 No supplementary treatment Class 4 Chemically converted (may be dyed to color as specified). With no supplementary coating or supplementary coating as specified

intended Use:

The phosphate coatings covered by this specification are intended for use where "heavy" coatings are required. Light phosphate coatings used as a paint base are covered by other specifications,... View More
