Copper Plating is a surface treatment that involves applying a thin layer of copper to the surface of the screw. It plays a crucial role in protecting the material, especially as an intermediate layer for following nickel and chrome plating. Copper plating is therefore often used as a preparatory step to improve the adhesion of…

Galvanic compatibility refers to the ability of different materials to come into contact without causing galvanic corrosion. When metals of different “nobility” are used together, they can cause damage due to corrosion. For instance, when zinc-plated steel and stainless steel are in contact in humid or marine environments, water serves as an electrolyte, accelerating the…

In the industrial field, the use of lubrificants is important to reduce friction between mechanical components and prevent the risk of seizing. However, traditional fluid lubricants have some limitations: -tendency to dirty -dosage difficulty -risk of dispersion into the environment -over time they can degrade and become ineffective or even harmful All these limitations can be…

WHAT DO YOU KNOW ABOUT BLACK OXIDE TREATMENT?   Black oxide is a surface treatment for stainless steel pieces that combines aesthetic needs with technical performance.   The burnishing process provides that the screws are submerged in specific oxidising solutions at a temperature between 120 and 130° C. This phase allows the formation of a thin layer…
