Long stainless steel gears and splined shafts are the critical arteries of heavy industrial power transmission, but the extensive CNC hobbing and milling required to cut them leaves behind massive amounts of iron contamination. If left untreated, this contamination causes rapid surface rusting and accelerated mechanical wear. The Passivation Treatment by IG Quality Industries is a non-destructive chemical bath specifically engineered for these high-value mechanical components. We utilize oversized, temperature-controlled immersion tanks capable of accommodating elongated gear shafts. The acid bath meticulously strips away free iron from the root and crest of every gear tooth without etching the metal, instantly promoting a thick, protective passive chromium layer that ensures the gears run smoothly, cleanly, and rust-free over millions of rotational cycles.
