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.

What's NO.1 mean in stainless steel plate 304NO.1? NO.1 in stainless steel plate 304NO.1 means the surface of stainles steel plate, which is a classification way of stainless steel . The detailed is as follows: NO.1 silver white, which is a rough, matte surface after hot-rolled to a specified thickness, then annealed and descaled processing. NO.2D silver white, it is heat treatment and pickling after cold rolling, a kind of matte surface processing. 2D products are used for applications that do not have requirements on the surface of stainless steel plate. NO.2B, strong luster. It is a final mild cold rolling with polishing rolls to get luster. It is the most common surface finish and can also be used as a first step in polishing. BA is bright as a mirror, but is usually a bright annealed finish with a highly reflective surface. It is used for building materials, kitchen utensils. NO.3 coarse grinding. Grind NO.2D and NO.2B stainless steel plate with 100~200# (unit) ...
316 and 304 stainless steel are austenitic stainless steels, both of them are have good characters such as rust resistance and corrosion resistance. However, there are obvious differences in high temperature mechanical properties and special medium corrosion resistance. HCADTO will tell you the differences between the them: 1. Corrosion resistance: the corrosion resistance of them are similar, but 316 stainless steel has added molybdenum on the basis of 304 for corrosion resistance, so the corrosion resistance of 316 stainless is better when the content of chloride ions is higher . 2. Price: 316 stainless steel has added molybdenum and nickel, so the price is a little higher than 304 stainless steel. 3. Uses: Both 304 and 316 stainless steel are food grade, but 304 stainless steel is usually used in household appliances and household containers, and 316 stainless steel is used in the production of medical equipment and tools.
