If we've placed a great deal of emphasis on materials, there's a good reason for this seemingly off-kilter approach. Materials must be heat treated if the mechanical and physical properties of a component are to comply with the rigorous requirements found in today's industrial applications.
The principal objective of this discussion is to determine the causes of distortion and residual stresses in heat treatment.
Fine manufacturing processes create sturdy cast iron items and robust steel-reinforced components that resonate with structural soundness, but such mechanical solidity doesn't just happen, not without an incorporated processing stage that intelligently manipulates key metallic properties until they fit a specified application.
In the foundry, blazing hot furnaces melt metal and produce castings, parts that are imbued with crude properties. It is then down to special alloy-refining facilities to alter those material characteristics, to intelligently manipulate key microcrystalline properties within the alloy so that the metal suits its application.
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.
