scope:

This standard covers the process and materials required for the electrodeposition of cadmium-titanium on high strength steel substrates. Subsequent heat treating techniques needed to insure low hydrogen embrittlement of steel are also described. This process is not authorized for use on steel heat treated above 1.65 × 10³ Pa [240,000 pounds per square inch (psi)] without the approval of the applicable Procuring activity.

This standard meets and exceeds the requirements of QQ-P-416.

Cadmium-titanium plating covered by this standard shall be of the following classes:

a. Class 1 - 0.013 millimeters (mm)(0.0005 inch) thick minimum.

b. Class 2 - 0.008mm (0.0003 inch) thick minimum.

c. Class 3 - 0.005mm (0.0002 inch) thick minimum.

Cadmium-titanium plating covered by this standard shall be of the following types:

a. Type I - Without supplementary chromate of phosphate treatment.

b. Type II - With supplementary chromate treatment. Type II is the preferred type and will be used whenever applicable.

c. Type III - With supplementary phosphate treatment.
