Vacuum powder magnetron sputtering coating technology plays a pivotal role in enhancing the interfacial bonding strength between diamond micron powder particles and metal binders. By depositing transition layers, such as Ti (titanium) and Cr (chromium), onto the surface of the diamond powder, this technology effectively reduces the shedding rate. Over time, it has transitioned from a simple single nickel coating approach to more sophisticated, diversified, and functionalized multilayer film systems. Examples of these advanced systems include Ti/Cu and Ti/Cr combinations, which are designed to achieve a harmonious balance of robust bonding, high electrical conductivity, and excellent thermal conductivity.

However, the widespread adoption and scaling up of this technology in industrial settings encounter several challenges. Key bottlenecks include the need for efficient, uniform, and continuous coating processes for powders, stringent cost control measures, and the establishment of standardized operational procedures. To address these issues, Chenhao Vacuum has developed a range of coating equipment, including drum-type, vibration-type, and spiral lifting systems. These innovative solutions cater to the diverse surface modification requirements of various powder materials. Consequently, they have found extensive applications in emerging fields such as new energy technologies and heat sink manufacturing, showcasing their immense potential and broad application prospects.
