Is Nickel Strike allowed before Cadmium plating heat treated bearing steel?

December 15, 2020

Q. Have problems with adhesion of cadmium plating over 52100 steel (1% C, 1.5% Cr). Advice from experts in the field suggest a Nickel strike which yields positive results. Because of the Cr content, can we classify the 52100 as being corrosion resistant and/or passive whereby Nickel striking would be permissible IAW AMS2400 [affil. link to spec at Techstreet] and AMS2401 [affil. link to spec at Techstreet] ? Have run across articles stating that 52100 steel is corrosion resistant.

AMS2400 [affil. link to spec at Techstreet] refers to 'corrosion-resistant steel or similarly passive materials' in allowing a nickel strike.

Depending on who you talk to, 'corrosion resistant' steel has approximately 10.5% or approximately 11% chromium content.

At 1.5% chromium, it might be an uphill battle trying to convince someone that 521200 was a corrosion resistant steel.

? Marc,
Please detail your preparation steps: solutions, concentrations, temperature, time, current/no current, polarity, etc.
