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.

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.
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.
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.
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.
Pre-Process: In addition to offering both mechanical & chemical cleaning options, AOTCO specializes in creating solutions for complicated, difficult and tight-tolerance masking challenges. Post-Process: For clients with specialized needs AOTCO offers laser marking and engraving options, including color change caused by chemical or molecular changes, charring, foaming, melting, ablation, and more.
Part of our cornerstone goal of building long-term, collaborative & solution-oriented partnerships, AOTCO will devote reserved physical and human resource capacity for our clients with long-term finishing and deadline requirements. For these partnerships our commitment is that AOTCO manages the process, while YOU control the results.
