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
