Vauriotreated

Vauriotreated is a designation used in materials science to describe substrates that have undergone a surface modification known as vauriotreatment. The term is used for metals, polymers, and composites that have acquired a thin, conformal surface layer intended to alter properties without affecting bulk material.

Vauriotreatment typically begins with surface preparation, followed by exposure to a vauriotreatment solution or vapor containing reactive species. The process may incorporate controlled heating, compression, or plasma exposure and often concludes with a stabilization or passivation step. The exact chemistry and step sequence vary by base material and intended property enhancements.

Reported effects include increased hardness and wear resistance, improved corrosion resistance, enhanced adhesion of coatings, and changes in surface energy that affect wettability and dye uptake. Some variants may produce subtle color or gloss changes.

Common substrates include carbon steels, stainless steels, aluminum alloys, titanium alloys, and certain high-performance polymers. Vauriotreated parts appear in aerospace components, automotive parts, medical implants, and consumer electronics housings, where surface performance matters.

Not all materials respond equally; the process may introduce residual stresses or affect fatigue life if misapplied. Cleaning and compatibility with subsequent finishing steps must be considered. Environmental and safety considerations hinge on the chemicals used.

First described in technical literature and patent filings in the 2010s, vauriotreatment has since been discussed in industry white papers as a versatile surface modification. Adoption remains limited to certain sectors and vendors. See also related processes such as surface treatment, passivation, nitriding, and anodizing.
