PVD: Physical Vapor Deposition
PVD
An advanced technology that deposits thin and resistant layers, ensuring aesthetic finishes and superior performance on any surface.
Che cos'è il PVD?
La Deposizione Fisica da Vapore (PVD) è un processo avanzato in cui i metalli vengono vaporizzati in un ambiente a vuoto spinto e successivamente depositati su un materiale da rivestire. Questo metodo consente di creare un rivestimento uniforme e ultra resistente su una vasta gamma di prodotti.
I primi studi sui fenomeni alla base del PVD risalgono a metà del XIX secolo, mentre il primo brevetto per uso industriale è stato depositato da Thomas Edison nel 1892.
Questa tecnologia permette di depositare materiali che in galvanica non si potrebbero ottenere, offrendo quindi una maggiore versatilità in termini di finiture e applicazioni.
PVD advantages
LEM utilizes PVD technology to deliver innovative, high-performance coatings across a wide range of materials. Our advanced processes and state-of-the-art equipment ensure that PVD treatments not only enhance aesthetics but also provide exceptional resistance to wear and corrosion, making them ideal for various industries.
HIGH WEAR RESISTANCE
pvd-coated surfaces resist abrasion and daily use better than traditional coatings.
CORROSION PROTECTION
The PVD coating resists corrosion and ensures a color that remains unchanged over time.
WIDE RANGE OF FINISHES
PVD technology enables gold, black, bronze and various customizable finishes.
FREE OF HARMFUL CHEMICALS
Unlike other processes, PVD is free from harmful chemicals and does not release hazardous emissions.
IDEAL FOR DIFFERENT MATERIALS
Steel, titanium, and brass are some of the substrates that can be treated with PVD technology.
COMPATIBLE WITH COMPLEX GEOMETRIES
PVD coatings maintain uniformity even on complex and detailed objects.

LEM's PVD division
Gli impianti di LEM utilizzano tecnologie PVD all’avanguardia, che garantiscono un controllo rigoroso del processo e la possibilità di rivestire una vasta gamma di materiali con finiture personalizzate. Le nostre tecnologie sono state sviluppate attraverso una continua innovazione, consentendoci di offrire risultati eccellenti per qualsiasi applicazione industriale e di design.
Gli impianti per la deposizione PVD possono lavorare articoli con dimensioni fino a 80 cm di lunghezza e 15 cm di diametro per le finiture con metallo prezioso, mentre le altre finiture possono essere applicate fino a un ingombro laterale massimo di 30 cm. In casi particolari è possibile eccedere le dimensioni indicate previo lo studio di appositi telai.
Prima di essere sottoposti al trattamento PVD, gli articoli devono essere adeguatamente preparati. Per l’ottone è necessaria una fase di elettrodeposizione galvanica. Inoltre, poiché il PVD replica fedelmente la superficie del pezzo, è fondamentale eseguire lavorazioni come lucidatura, satinatura o sabbiatura prima del trattamento.
FAQ – Frequently asked questions about PVD
PVD can deposit nearly any element from the periodic table that exists in a solid state at room temperature. For decorative applications, titanium, zirconium, and chromium are commonly used due to their excellent corrosion resistance and mechanical properties.
PVD coatings are extremely thin, typically ranging from 0.4 to 3 microns, ensuring they do not affect the dimensional tolerances of components.
The feasibility depends on the material being deposited. LEM’s optimized PVD processes allow simultaneous treatment of steel and brass. However, when processing mixed materials, the method must be adapted to the most sensitive material.
Yes, we offer solutions for removing most PVD coatings used in decorative applications. Depending on the item’s material, additional finishing steps may be required after removal to prepare it for further processing.
The LEM PVD Division is a specialized research and production facility where our technicians and engineers continuously test and refine PVD deposition techniques. This hub of innovation develops sustainable and customized solutions for a variety of industries.
