Blackening (cooked to black) · Appearance: Black. · Rust resistance: Moderate; an oxide film forms on the surface, which is better than the original color. · Main advantages: Higher wear resistance; the film layer is thin (0.5–1.5 μm), so it does not affect precision; it is often used in gourd-shaped chains. · Suitable for use in environments with poor air circulation, or in situations where certain wear resistance is required.
