Etching zirconium with Multi-Etch
How to etch zirconium with Multi-Etch, the safer alternative to hydrofluoric acid
Multi-Etch was originally developed for use on titanium, and is a perfect low-acid (pH 6.8) alternative to hazardous hydrofluoric (HF) acid for etching zirconium
|Process||Etch time (minutes)||Notes|
|150–160°F double strength||1||Slightly better colors|
|Note: times are for removing high-voltage green; lower voltage colors will take less time to remove.|
|Process||Etch time (minutes)||Surface change|
|150–160°F double strength||3||Pitted|
|Process||Etch time (minutes)||Etch depth (inches, cumulative total)||Surface change|
|150–160°F double strength|
|2||0.00093||Trend toward pitting|
|3||0.00133||Trend toward pitting|
