Many different kinds of metals are used for tools and other uses. Steel is probably the most common metal used for every manner of application. Steel is used for everything from eating utensils to offshore oil rigs. The different processes by which steel is refined determine the characteristics of that steel. The inclusion of seemingly tiny amounts of carbon can make steel harder but more brittle. Including other materials can make it more flexible or rust-proof. These different kinds of steel are almost all susceptible to rust or corrosion, even the ones that are designed to resist it. The most common problems with metal begin at the surface of the metal, though. Therefore, protecting the surface of metal will protect the metal.
Protecting the Surface
To protect the surface of the metal, you should consider chemical blacking. Blacking is the process of altering the chemical composition of the surface of metal. It’s called blacking because it typically makes the metal turn black on the surface. It is not a protective coating as some other options; a protective coating can be scratched or can wear off. Blacking is actually changing the composition of the metal so that the outer layer of metal is black or brown. That will make it impervious to rust and corrosion because the composition has changed. In addition to protecting the surface of the metal, it will also change the colour to black. That is worthwhile for several reasons.
Reducing Eye Strain
Research has found that over time, the glare of light shining off of metal can actually cause eye strain. Those who work in industrial and agricultural applications will grow tired over time as the strain grows. It can also make it much more difficult to work in low-light conditions. If you’re working in a low-light condition, you likely have a torch or some other kind of handheld light. However, that light will bounce off the shiny metal surfaces and make it more difficult to work. Instead of that, a blacked metal will not reflect the light nearly as brightly. That will make it much easier to shine into dark places. Paradoxically, dark metal is easier to see in the dark than bright metal.
Browning is similar to blacking but it results in a different colour of metal. It’s often used to make metal look antique. It also was used for many antique firearms, depending on the available chemicals at the time the firearms were produced. If you want your metal to look antique, browning will help you create a believable patina over the metal. You should ask professionals about the difference between blacking, browning, and bluing. Also, ask them which is right for you when you make your decision.
