Ceramic mold surface PCVD technology developed successfully

Xi'an Jiaotong University and Beijing University of Aeronautics and Astronautics have recently completed the project of "Plastic Ceramics Surface PCVD Technology Development and Industrial Application". This achievement is of great significance in promoting the technological progress of China's manufacturing industry and improving the quality of mold and die products and core competitiveness.
PCVD (plasma-assisted chemistry) small laboratory equipment has been developed in China, but only for DC plasma power. Molds require large industrial equipment and must be equipped with pulsed DC power sources, which have not yet been developed at home. Foreign countries such as Japan and Austria have such industrial equipment. The project completed by Xi'an Jiaotong University and other units solved a number of theories and applied technologies for the preparation of hard films by pulsed DC PCVD, broke through the power bottleneck and process stability structural design of industrial equipment manufacturing, broke the monopoly of foreign technologies, and lowered equipment. cost. Can be applied to modern manufacturing, mainly the molding and processing of mechanical parts, such as CNC machine tools, integrated circuit high-speed drills, aero engine blades, etc., but also can be applied to the processing of various types of mechanical parts, such as cylinder pistons, friction disks Pins, transmissions, and couplings.
