Surface finishing / bluing

Bluing is a process that involves immersing ferrous workpieces in a blackened, browned material.

A more corrosion-resistant layer was introduced into the workpiece by immersing it in a bluing salt bath.

This causes it to turn black. Subsequent oiling provides corrosion protection.

Improved again.
