In documenting the essential characteristics of the black oxide coating process, we’ve illustrated the engineering science and the main advantages of the procedure. More than a smart finishing process, a material depositing technique; the metal surfaces that undergo this process are actually converted into a new form, one that shields the underlying metal while gifting it with a superb onyx-black finish.
Industrial foundries manufacture formidable products, mammoth components and intricate parts that go into service in the harshest applications. The thing is, we can’t just melt iron and fill a cavity. The cooled metal part would hold its form and even look tough enough to handle the stresses of its coming role, but this isn’t the way of steel and cast iron.
