For metals, in order to improve the performance of the metal, manufacturers carry out surface treatments to improve the metal. In our daily life, the common metal surface treatment techniques are: pickling and purification treatment, electrolytic polishing treatment, oil and rust removal treatment, Read More

Surface treatment is a process method for forming a surface layer on the surface of a substrate material that differs from the mechanical, physical and chemical properties of the substrate. The purpose of surface treatment is to meet the product's requirements for corrosiSurface treatment is a process method for forming a surface layer on the surface of a substrate material that differs from the mechanical, physical and chemical properties of the substrate. The purpose of surface treatment is to meet the product's requirements for corrosion resistance, wear resistance, decoration or other special functions. The following are common surface treatments.on resistance, wear resistan Read More

PVD coating is a common tool coating used in industrial production and has been developed for a long time, and is widely used in cutting tools, tooling and other finishing industries. However, as the level of industrial production increases, the requirements for tool coatings are becoming higher and higher. Although the preparation methods are progressing, it is inevitable that there will still be some shortcomings in the preparation process. Read More

The specific principle of PVD (ion coating) technology is the use of low voltage, high current arc discharge technology under vacuum conditions, the use of gas discharge to evaporate the target material and make the evaporated material and gas are ionised, the use of electric field acceleration, so that the evaporated material and its reaction products deposited on the workpiece.

Vacuum coating technology did not take long to start and it was only in the 1960s that CVD (Chemical Vapour Deposition) technology was applied to cemented carbide tools internationally. As the technology needs to be carried out at high temperatures, the coating type is single and the limitations are great, therefore, its development is not poor at the beginning. PVD coating technology, on the other hand, has two characteristics: low temperature and high energy, and can be applied to almost any substrate, so it is not surprising that the range of applications is very wide. The development of vacuum coating technology has also seen the emergence of new technologies such as PCVD (physical chemical vapour deposition) and MT-CVD (medium temperature chemical vapour deposition), and a variety of coating equipment and coating processes have emerged, and there is now a pleasing scene of a hundred flowers blossoming in this field.

There are four factors affecting the quality of cleaning, respectively: cleaning time, chemicals, mechanical action and cleaning fluid temperature, the four factors also affect each other, a weakening of factors, can be enhanced through the role of the other three factors to compensate, and vice versa. In these four factors, the cleaning time of the smaller is also the pursuit of the goal, so as to improve the efficiency of cleaning. Shorten the production time and delivery cycle. Read More

The tool is one of the most active elements of the cutting system. With the development of technology, the feed and cutting speeds of coated tools have been increased, while their service life has also been extended. Therefore, in today's rapidly developing machining technology, the performance of tools has gained importance, with coating technology being a key technology in tool manufacture. Read More

PVD coating technology, suitable for injection moulding, hardware, die-casting moulds, parts and cutting tools, has anti-wear and high temperature resistance characteristics, the service life can be increased by 2-10 times, can significantly improve production efficiency and reduce production costs. At present, there are still many mould companies who lack understanding of this technology. Read More

The homogeneity of the thickness of the coated film on a magnetron sputtering vacuum coating machine is a very important indicator of the film-forming properties, so it is very necessary to study the homogeneity of the coated film on a magnetron sputtering vacuum coating machine. Here enijor gives you more details. Read More

PVD is a surface treatment process in which metallic or non-metallic materials such as titanium, graphite, gold, crystals and gases are formed on a substrate by sputtering, evaporation or ion plating. PVD has many advantages over traditional chemical plating methods: for example, it is a green and environmentally friendly process; it is not harmful to the operator; and the film is strong, dense, corrosion resistant and of uniform thickness.

PVD processes can generally be divided into three types, namely vacuum vapour deposition, sputter coating and ion plating. The main barriers in the pvd coating materials industry are: technical barriers, financial barriers, talent barriers, and brand barriers Read More

PVD vacuum coating will greatly improve the hardness and adhesion of medical devices. The biocompatibility of the coating is a prerequisite for its use on medical devices. Read More

With the development of economy and the improvement of living standard, people like to decorate watch cases, watch straps, clothing, lighting, glasses frames, indoor and outdoor decorative parts, hardware luggage, mobile phone cases, mobile phone video screens sanitary ware, food packaging and other decorative items finely decorated with colorful. Here, Yingliyue introduces you to the main applications of pvd vacuum coating technology! Read More

The application of PVD coating technology is divided into two main categories: decorative coating and tool coating. The purpose of decorative coating is to improve the appearance and colour of the workpiece, and to make the workpiece more wear-resistant and corrosion-resistant to extend its service life. The purpose of tool plating is to improve the surface hardness and wear resistance of the workpiece, reduce the friction coefficient of the surface and improve the service life of the workpiece; this is mainly used in various knives and scissors, turning tools (such as turning tools, planing tools, milling tools, drills, etc.), various hardware tools (such as screwdrivers, pliers, etc.), various moulds and other products.

Physical Vapor Deposition (PVD) technology refers to the use of physical methods under vacuum conditions to vaporise the surface of a material source (solid or liquid) into gaseous atoms or molecules, or partially ionised into ions, and to deposit a thin film with a particular function on the surface of a substrate through a low pressure gas (or plasma) process, Physical Vapor Deposition is One of the main surface treatment techniques. PVD (Physical Vapour Deposition) coating technology is divided into three main categories: vacuum evaporation coating, vacuum sputtering coating and vacuum ion coating. The main methods of physical vapour deposition are: vacuum evaporation coating, sputtering coating, arc plasma coating, ion coating and molecular beam epitaxy. The corresponding vacuum coating equipment includes vacuum evaporation coaters, vacuum sputtering coaters and vacuum ion coaters. Read More
