Allow a few seconds for color to develop before cleaning
Black not possible unless lacquer filled
Deep etch BEFORE anodizing (minimum .002)
Reduce amperage if blurring occurs
Use low amperage, oil part after cleaning
Use low amperage
If coating is heavy, parts should be deep etched
Allow time for oxide to stabilize before cleaning
Blotting action improves frosted contrast
Deep etch BEFORE unless coating is very thin
Dark mark usually not stable
Use minimum amount of Electrolyte (work dry)
Use high amperage
Use low amperage, work dry, wait before cleaning
Use low amperage & minimum Electrolyte
Use low amperage & minimum Electrolyte
Use DC if AC not dark enough & minimum Electrolyte
Use DC if AC not dark enough
Allow time for oxide to stabilize before cleaning

ELECTROLYTES
MARKING METHODS' laboratory controlled Electrolytes are the result of years of research and development. They are carefully
formulated and cataloged by formula and batch number to mark varied metals and surface treatments.
The Electrolytes are
buffered salt solutions, pH balanced, and are completely harmless to parts and surrounding equipment when used as directed.
NUCLEAR GRADE ELECTROLYTES (non-chloride or halogen free) can be furnished that contain less then 250 ppm of chlorides (halogens), sulfur, mercury, copper, zinc, and
lead. These Electrolytes can be certified to meet MIL STD's 767 and 792 when requested.
Use a light oil film (CPO) prior to marking on sand or grit blasted surfaces to prevent blurring. Oil fills the open grain surface of the metal. This procedure is also very effective
before marking metals or plating that stain easily. Do not use gold (DF2) stencil for this application.
Submit sample parts to our laboratory for Electrolyte evaluation of particularly difficult applications.
*NOTE: POWER UNIT SETTINGS FOR ALL DEEP ETCH MARKING SHOULD BE DC AND DEEP ETCH WITH RHEOSTAT AT 3 OR HIGHER. AMPLE ELECTROLYTE MUST
ALWAYS BE USED. DEEP ETCHING MAY PRODUCE A FUZZY OR BLURRED MARK. A LIGHT BUFFING AFTER CLEANING WILL SHARPEN THE LINE DEFINITION.
