MIL-R-46085
MIL-R-46085 Technical Information
About: Electrodeposition of Rhodium over metallic surfaces.
Classification (thickness):
Class 1 – 0.000002 inch minimum
Class 2 – 0.00001 inch minimum
Class 3 – 0.00002 inch minimum
Class 4 – 0.0001 inch minimum
Class 5 – 0.00025 inch minimum
Underplating:
Surfaces other than nickel, silver, gold, or platinum shall be nickel plated in accordance with QQ-N-290. Underplating must be used when parts are corrosion or heat resistant steels. Underplating thickness will not be used in determination of rhodium plating thickness.
Finish:
When required reflective purposes, the plating shall be sufficiently smooth to give a reflectance of at least 75%.
When rhodium plated surfaces are to be tested for reflectivity, the angle of reflection and incidence shall be measured at 45 degrees plus or minus two degrees. A flat surface shall be used for reflectivity tests.
Ordering Data:
Procurement documents should specify the following:
- Title, number, and date of the specification
- Class of plating required
- Whether a preproduction sample is required
- If surface is required for reflective purposes
- Sampling plan and acceptable quality level
- Preparation for delivery requirements
