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

Services & Capabilities
Electroplating
Electroplating
Electroplating is a process by which one metal is deposited onto a base metal (substrate). These deposited metals offer a variety of benefits including thermal and electrical conductivity, corrosion resistance and more. AOTCO electroplates a wide variety of both standard and exotic metals.
Learn MoreAnodizing
Anodizing
Sometimes called a “conversion coating” Anodizing is an electrolytic process in which an oxide (anodic) layer is chemically built on the surface of the substrate material, providing anti-corrosion and other benefits. AOTCO offers, Type I, Type 2, Type 3 and Titanium anodizing services.
Learn MorePassivation
Passivation
Passivation is a term for a variety if processes that make a metal (most commonly stainless steel) or other substance unreactive, or passive, by altering the surface layer or coating the surface with a thin inert layer. AOTCO performs both citric and black oxide passivation techniques to a range of specifications.
Learn MorePlating Substrates
Plating Substrates
AOTCO plates on a wide variety of Common, Exotic and Non-Metallic substrates, bringing exceptional expertise to magnesium, titanium, beryllium, BeCu, TeCu, tungsten and more. In some cases we pass as high as 450 degrees celsius, allowing for high temperature soldering, brazing, or post machining operations after plating.
