The main difference between PVD (Physical Vapor Deposition) and electroplating is the processes they employ and the properties of the coatings they produce.
PVD coatings have improved scratch and wear resistance, more color options, and a cleaner, safer process compared to electroplating. PVD coatings also offer the option of use after electroplating for additional wear-resistance and aesthetics.
PVD involves vaporizing solid physical particles into a plasma, which is a line-of-site deposition. This means that the coating is applied in a directional manner, resulting in better thickness and uniformity on uneven surfaces. On the other hand, electroplating involves the deposition of a metal coating onto a substrate through an electrochemical process, resulting in a more uniform and conformal coating.
Another difference is that PVD does not involve any chemical reactions during the deposition process, while electroplating relies on a chemical reaction to deposit the coating onto the substrate.
In terms of the materials they can deposit, PVD is generally more versatile and can deposit a wide range of materials including metals, alloys, ceramics, and even diamond-like carbon coatings. Electroplating, on the other hand, is limited to metals and alloys.
Additionally, PVD requires complex machines and skilled operators, which can result in higher costs compared to electroplating.
Overall, PVD coatings offer several advantages over electroplating in terms of durability, aesthetics, and versatility, but they also come with higher costs and require specialized equipment and expertise.
