I stumbled on a procedure called nitriding which case hardens steels. And some sites stated that it fundamentally doubles the surface area hardness of some steels like Instrument steels, which made me curious if anyone has tried out nitriding knife steels and if yes, how the knives accomplish?
Powder coating is a singular finishing process that utilizes electrostatically charged particles which happen to be then cured below warmth to form a resilient protecting layer.
The architecture in the polyester resin and kind of curing agent have A significant effect on crosslinking.
The appliance of powder can be achieved in both of two strategies; spraying or dipping. Throughout the spraying approach, a gun electrostatically expenses the powder which can be then sprayed on to the item. The dipping process includes submerging the article right into a fluidized bed of powder that also carries an electrostatic demand.
Together with its mechanical and aesthetic benefits, powder coating is picked out for its purposeful Attributes, for instance electrical resistance.
The price-success of powder coating is an additional considerable advantage to engineers. The procedure is usually inexpensive than liquid coatings due to the fewer materials being used (mainly because it thickens through the curing phase) and a chance to directly utilize powder to heated pieces without the require For extra processing steps.
In general, powder coating is a superb option for metal elements, but its software to non-metal components should be thoroughly regarded as and brought with warning.
Masking blocks off regions of the portion that don't will need powder coating. It guards these parts within the coating system and makes sure clean up threads or machined areas. Coating

To make certain uniform protection, sections is usually Carefully tapped to enable the powder to settle evenly across the surface. As soon as applied, the powder then must be cured either by heating in an oven or exposing to ultraviolet light, which curing process is crucial towards the good results in the powder coat.

These charged powder particles then adhere to your grounded substrate. Utilizing a tribo gun needs a different formulation of powder than the greater widespread corona guns. Tribo guns will not be topic to several of the issues related to corona guns, having said that, for example back-ionization as well as Faraday cage impact.
I have a Seiko 007 by using a PVD coated bezel on it. I have worn it a fair total (not every day while) and I don't little one it, there are no scratches throughout the coating.
Using UV LED curing techniques, which are hugely Electrical power effective and do not deliver IR Power with the lamp head, make UV-cured powder coating even more appealing for finishing various warmth-delicate materials and assemblies. An extra reward for UV-cured powder coatings would be that the full process cycle, application to treatment, is faster than other coating procedures.[three]
