EMBRITTLEMENT TEST

I WOULD LIKE TO KNOW WHEN A DE-EMBRITTLEMENT TEST IS DONE ON A PART - BEFORE OR AFER PHOSPHATE COATING?

And what might the de-embrittlement test be?

Embrittlement relief is performed after phosphating. Embrittlement is a combination of susceptible alloy and a hydrogen environment. The hydrogen environments are typically acid baths used for cleaning and coating/plating. Hence, embrittlement relief AFTER those processes.
