What is PVD coating ?
PVD stands for Physical Vapor Deposition.
PVD Coating refers to a variety of thin film deposition techniques where a solid material is vaporized in a vacuum environment and deposited on substrates as a pure material or alloy composition coating.
PVD coatings surpass traditional electroplated coatings, it's more corrosion resistant and have superior hardness.
The process of PVD coating
During the process, first of all the stainless steel is cleaned to make sure that the coating will bond well. The steel is then placed in a vacuum chamber with a “target” metal; this will be used to create the coating. A high vacuum level is needed in the coating chamber, then a small amount of argon gas is introduced. A high voltage circuit is used in order for the stainless steel and target to bond or adhere. This allows the argon ions to bombard the target to release atoms of the target metal, which are deposited on the stainless steel substrate as the coating. This PVD process is called sputtering; resulting in the deposition of plasma on the stainless steel surface which gives it its new strength and shine.
The coloured surface coatings that can be obtained using PVD include: gold (TiN), rose gold (ZrN), bronze (TiAlN), blue (TiAlN), black (TiAlCN), as well as a dark red (ZrN). This ceramic coating which is produced is very thin, making the texture of the underlying finish still visible. These PVD colours will not fade over time and more abrasion-resistant than colouring which is done by the electrochemical processes.
A spectrum of colour options for PVD coating
When it comes to stainless steel you’re not just restricted to simply silver. There are a rainbow of colour opportunities which can be achieved through the Physical Vapour Deposition (PVD) process. HCADTO Stainless Steel Co., Ltd. the Stainless Steel Division of ADTO GROUP, is one of the leading manufacturers of stainless steel products in China.

Colored stainless steel plates can be used in hotels, guesthouses, entertainment venues, high-end brand stores, elevator panel, etc., and their decorative effect and corrosion resistance are better than ordinary stainless steel. Generally, stainless steel color plates are distinguished by three aspects: 1. Surface treatment includes wire drawing, mirror surface, sandblasting, chaotic grain, compound hair grain, cross grain, etc., 2. Surface colors include gold, rose gold, champagne gold, black titanium, brown gold, etc. 3. No fingerprints are generally divided into glossy and matte. With the advancement of technology, Changsha HCADTO Stainless Steel Co., Ltd. special materials such as stainless steel colorful plates, colored water corrugated plates, and colored stainless steel embossed plates are gradually knowed by people. specializes in the production of stainless steel colored plates with various patterns, and can also be customized according to customer requ...
1. 304 stainless steel plate is shiny and has a good gloss with smooth touching, while 201 stainless steel plate is dark and has no gloss with rough uneven touching. In addition, touching both of them with wet hands, the water-stained on the 304 stainless plate are easier to erase than 201 stainless plate. 2. Using a grinder to install the grinding wheel to grind and polish the two plates gently. When grinding, the sparks of the 201 stainless plate are longer, thicker, in the contrary, the sparks of the 304 stainless plate are shorter, thinner, and less. 3. Apply stainless steel pickling paste to two stainless steel plates respectively. If the color is dark, it is 201 stainless plate, and if it is white or does not change color, it is 304 stainless steel plate. With the advancement of technology, Changsha HCADTO Stainless Steel Co., Ltd. special materials such as stainless steel colorful plates, colored water corrugated plates, and colored stainless steel...
When brown rust spots appeared on the surface of 304 stainless steel pipes , the customers may doubt that stainless steel would never rust, it must have quality problem. In fact, this is one-sided misconception about stainless steel. Stainless steel also can get rusty under certain conditions. Stainless steel has the ability to resist atmospheric oxidation, also has the ability to resist corrosion in media containing acids, alkalis, and salts. But the resistance to corrosion is different with the chemical composition, working conditions and surrounding medium type and change. For example, 304 steel pipes has absolute good resistant corrosion in the dry cleansing air, but not in sea fog. Therefore, not any kind of stainless steel can resist corrosion and rust at any time. The are some condition that we shoule take care for it may cause damage to the protective film on the stainless steel surface and lead to corrosion. 1. Cleaning and scrubbing stainless steel pipe freq...
