Blackening is a traditional term for the process of producing a dark, decorative finish on metals, and the process offers many benefits to a range of industries. One of its most important properties is it can be used for precision parts, as the process does not add anything to the object’s dimensions, and unlike a coating, it will remain in pristine condition. The process itself changes the chemical composition of some metal surfaces, and this creates a solid barrier against moisture and corrosion, making it a favourite in both the manufacturing and engineering industries.
The great thing about blackening is that the process gets into every nook and cranny, totally covering the metal object, no matter how complex the shape. This is ideal for machined parts, and with total protection, the components will have a much longer life, and with online experts in the blackening process, such as Blackfast, the process can be professionally applied, and they even sell kits for blackening.
No Extra Dimensions
Unlike protective coatings, there is virtually no increase in the dimensions of the treated components, making it the ideal choice for anything that is precision made and requires protection against the elements. Many internal combustion engines use parts that have undergone the blackening process, as it proves to be the most efficient way to offer high grade protection at an affordable price, and with zero tolerance, the parts cannot be any larger.
Range of Metals
The blackening process can be carried out on the following metals:
The blackening process has been refined for all of the above metals, and by discussing your needs with a supplier, you will get the best advice on how to treat your items.
The Blackening Process
There are several stages to the blackening process, but basically, it has been refined to a simple immersion dip, and this room temperature dip ensures that the entire surface is covered with the solution. Once the blacking has been completed, a final dip in dewatering oil will ensure protection against corrosion.
Cost Effective and Simple
With the manufacturer’s instructions and ready to use kits, it is possible to treat a range of metal objects, and the finish will ensure long life with a one-time treatment. Many industries are reaping the benefits of metal blackening and if you think it could help your business, an online search will put you in touch with the market leader, who can advise you accordingly.
The wide range of uses makes metal blackening the most popular way to protect certain metal surfaces, and with different effects possible, you really need to talk to the experts. If you are based in the UK, for example, there are specialist companies that have refined and perfected the ancient art of metal blackening, and its decorative value is not to be underestimated. For industrial use, it certainly ticks all the boxes, and with many precision parts protected by blackening, the industry looks like it is here to stay.
