What's inside
- ✓Zero-assumption fundamentals — a CHEMICAL conversion coating with NO electric current
- ✓Trivalent (Cr³⁺) chromate: the RoHS-compliant modern passivate that replaced hexavalent
- ✓The key lesson: trivalent is a passive barrier (NOT self-healing) — needs a topcoat/sealer system
- ✓Clear/blue, iridescent, and black options; the passivate + topcoat that hits hex-level salt spray
- ✓Care points: drag-in, pH, and keeping Cr³⁺ from oxidizing to Cr⁶⁺
- ✓Safety reframed honestly — not a Cr VI carcinogen, but still an acidic bath with cobalt topcoats
- ✓Where trivalent fits vs hexavalent chromate (RoHS, performance, cost)
- ✓20-question completion test, answer key, and certificate of completion
- ✓Available in English and Spanish (professional shop-floor Spanish)

Training Manual
Chromate Conversion Coating (Trivalent) — The Complete Training Manual
A 49-page, plain-language training manual for trivalent (Cr³⁺) chromate conversion coatings — the RoHS-compliant modern passivate for zinc-plated parts that replaced hexavalent chromate. A conversion coating (a chemical film, NO electric current). Written in a friendly, “for-dummies” style that assumes zero prior knowledge, it teaches conversion-coating fundamentals, then trivalent specifically: built on trivalent chromium (no hexavalent) to meet RoHS/ELV/REACH; the central operator lesson that trivalent is a passive barrier (NOT self-healing like hex), so it relies on a thicker, uniform passivate PLUS a topcoat/sealer system to match hex salt-spray; the clear/blue, iridescent, and black color options; and the care points (drag-in, pH, and not letting Cr³⁺ oxidize to Cr⁶⁺). Safety is reframed honestly — trivalent chromium is not a carcinogen like Cr VI, but it's still an acidic bath with cobalt-bearing topcoats, so PPE and ventilation still apply. Ends with a 20-question completion test, answer key, and a printable certificate of completion.
