(8)In the mechanical manufacturing, the NaOH solution is usually heated to blacken the workpiece, and the cost is relatively low compared with the galvanized chrome plating, and the effect is good. However, the black oxide film formed by blackening has a thickness of 0.5 to 1.5 μm and has a corrosion resistance lower than that of galvanizing or chrome plating. Therefore, blackening is a surface treatment method that is relatively inexpensive and generally resistant to corrosion.
