Zinc plating problems in case-carburized component

February 6, 2010


I request your assistance. We are plating an externally threaded case carburized component, which despite the heat-treaters efforts has scale. This component looks like a disc (the Outer Dia is 40 mm & the thickness is 13 mm).

Due to case hardening, the thin cross-section of external threads are very hard & somewhat brittle.

Should we zinc phosphate as a pre-treatment for zinc plating? (I don't even mind the extra cost of this, if we can be assured of good quality). Or would you have any other suggestions

I would much appreciate your recommendations on how to deal with this problem. Thanks!

Dear Anup Sagar,

if the part is for Asthetic reason, Zinc plating will not give 100% Guarantee. May be you need to think of powder coating.

Still you are not able to change the Zinc plating.
Before plating do the Alumina blasting and try for Zinc plating or before your Polishing do the Descaling process.
