A major automotive supplier had to convert its hexavalent olive drab coating to a trivalent black chromate for its zinc-alloy plating.
Greystone offered zinc-alloy plating with trivalent black chromate that provided the necessary salt-spray performance.
Typically, trivalent chromates have had difficulty meeting corrosion protection requirements. The new "ELV" directive implemented
by the European community on automakers has severely tested electroplaters and chemical suppliers in the elimination of
hexavalent chromates in the zinc passivation process. Naturally occurring 'contaminants' within the plating process drag-out from
one tank to the other, and as these 'contaminant' levels rise within the chromate bath, the corrosion protection ability of the
Greystone has been using trivalent chromates for over 5 years working very closely as a Beta-site for a leading chemical supplier.
These years of experience has proven very valuable to understanding the complexities to trivalent chromate applications, process
parameters and overall performance with respect to corrosion protection and periodic salt-spray testing. Through statistical process
control, upper and lower control limits were established on various process chemistry components and were verified with each
production run. With consistent & regularly-monitored laboratory chemical analysis, Greystone is able to ensure optimum trivalent
chromate application & performance with each production run.
Greystone's experience using trivalent chromates provided a solid and predictable transition to hex-free chromate plating from
hexavalent chemistry. The customer was able to confidently provide samples with superior corrosion to their end customer to
ensure a smooth transition from hexavalent to trivalent chromate chemistry.
