There are many stayblack coating uses, and as plating suppliers, this is a question we get asked a lot. Unlike tin, silver, copper, nickel or zinc plated parts, Stayblack is a chemical conversion. By modifying the passive oxide layer of the stainless steel, a matt black appearance is created for the finished stainless steel. The black stainless steel coating is in use in the military and the automotive industries in particular.
Stayblack Coating In The Military Industry
Some industries need bright silver coloured parts. However, others need to make sure their parts are of the same uniform black colour. For instance, military applications, often require their turned parts, fasteners, and small pressings to maintain a matt, black, non-reflective appearance – especially on stainless steel.
Stayblack coating offers an alternative to the standard metallic appearance. This black finish is often used on aerials, latches, clips, fixings, and other stainless steel components, which need to stay black.
As well as the military and automotive industries (where it’s used for external fasteners, under bonnet fasteners, and trim accessories), other Stayblack coating uses include components in important equipment in the medical. As well as in optical, scientific fields, and aerospace applications.
Advantages Of StayBlack Coating
Some of the main advantages to using the Stayblack coating are that it does not change the dimensions of the component. It can also tolerate hot water, atmospheric weathering, and temperatures of up to 500 degrees centigrade. It does so, all without changing in either appearance or form.
There is no chance of hydrogen embrittlement occurring, primarily due to the fact that it is a non-electrolytic process. The surfaces can be bent or crimped after treatment.
The coating will also stay the same. There’s no flaking, peeling or chipping when you use Stayblack. There are also options for how the parts are delivered with this type of coating. You can get them with a range of lubricants, or have them dry to the touch.
Parts treated with Stayblack will retain their colour far longer than untreated parts. In addition, the stainless steel will retain its inherent corrosion resistance.
