Adhesion/Bond strength of hard
chrome deposits in various type of baths
+++++
Do we have any comparative data study to check the Bond strength
of Hard chrome deposit on M.S and C.I,in different processes like
conventional/SRHS/and organic additives used chemistry.

+++++
Long ago I remember having read an article stating a maximum of
20,000 psi of bond strength for hard chrome over steel. Adhesion is
more a function of surface preparation, internal stress and external
work done to the plate than of the chemistry itself, with the
exception of high alloy steels such as stainless, where the fluoride
chemistry is better.
