Coating is to tools and parts what clothing is to human beings. When it comes to metallic coating, often times people will use hot-dip galvanizing, electroplating or thermal spraying by default because that is what has always been used. But many times, vacuum coating is a better solution, as it provides a more uniform deposit, improved adhesion, no edge build-ups, and wider choices of metals and metal compounds to be deposited.

BITE Vacuum Technology applies metal or metal compound coatings to tools and parts using an arc vaporization process. As the name suggests, arc vaporization creates multiple electric arcs to vaporize the cathode, resulting in a blast of metal ions to bombard the material to be coated.

Medium frequency pulsed magnetron sputtering is a physical vapor deposition process that combines pulsed power technology, magnetron sputtering deposition, and arc evaporation into one operation.

Get a piece of PVD coating equipment and apply titanium or its compound to stainless steel sheets or pipes. According to the kind of gaseous environment used in the vacuum chamber, different coatings of metal compounds can be formed on the steel surface.

Highlighted on this page is PVD coating equipment designed specifically for coating ceramic tiles and wares including tablewares, stationeries, and sanitary wares. This vacuum coating system is complemented by the feed track and drying oven.

To vaporize solid metal targets, there are many ways to do that. One way is by electric resistance heating, or more technically known as resistance evaporation. This vacuum metallizing system is specially designed to apply coatings of aluminum or aluminum compounds.

If most of your coating work involves glass, then this PVD coating equipment will meet your needs. At the heart of this vacuum coater is a magnetron sputtering system that uses pulsed power supplies to ionize the target (solid metal) and ensure optimal deposition uniformity.

There are many different ways to apply metal coating to tool's surface, among which vacuum coating is the most eco-friendly method. Coating is to tools what clothing is to human beings.

BITE Vacuum Technology provides energy-saving, eco-friendly vacuum heat treatment equipment with guaranteed process technology. Two most important uses of BITE vacuum furnace have been in vacuum oil quench and gas quench.

Not only do we provide vacuum coaters, but we also keep in stock a diverse range of auxiliary equipment for your choices, including the vacuum pump, measuring instruments, power supply, and target materials.

Vacuum coating is the process of adding a thin film of coating to a material. The material to be coated is technically known as the substrate. What acts as the source of coating is called the target. The coating process is formally referred to as deposition, whereby metals, alloys, or compounds are deposited on the surface of the substrate.

True to its name, vacuum coating takes place in a vacuum environment or a low-pressure plasma environment. A plasma is an ionized gas, providing positive ions and free electrons. An example of a plasma environment is the ionized argon gas. Another example is the ionized nitrogen. In some cases the material being deposited reacts with the gaseous environment to form a film of a metal compound, i.e., metal nitride, where the nitrogen comes from the gaseous environment, and the metal comes from sputtering or arc vaporization of a solid metal.

Sputtering deposition is a process whereby ionized gas, for example argon ion, hits the target (usually a solid metal) so hard that the ions in that metal are energized and sputter (bombard) the substrate to form a deposition.

Arc vaporization usually uses one cathode and two anodes to produce electric arcs. The electric arc vaporizes the cathode material into a plasma state. The ionization of atoms from the cathode is known as arc vaporization or cathodic arc technology. The free ions bombard the substrate and form a firm film of coating on its surface.

All these evaporation techniques mentioned above fall into the category of physical vapor deposition, abbreviated to PVD, which differs from CVD, short for chemical vapor deposition. Note that there is another technique of PVD, called ion plating, a process that is beyond our service range.

Because all our processes involve coating metal on the surface of objects in a vacuum environment, they are also called vacuum metallizing. The machine that conducts the process is referred as the vacuum coater, or vacuum metallizer.

Important
Many Chinese vacuum coater manufacturers confuse arc vaporization with ion plating. Some have even created the term multi-arc ion plating, which is now plaguing the website. The biggest difference between the two processes is that ion plating uses electron beams to evaporate the target material, whereas arc vaporization creates electric arcs to vaporize the target. So next time you come across the term multi-arc ion plating, there is a good chance that what it really means is an arc vaporization system.
