Zirconia Ceramic Rod with Metal Head is based on a zirconia ceramic rod as the core body, supplemented by a special metal head to form an integrated structure. The zirconia ceramic rod has excellent thermal shock stability and can maintain structural integrity in the temperature range of -200℃ to 800℃. At the same time, its surface is ultra-finely ground, with a roughness as low as Ra0.02μm, which can meet the needs of micron-level positioning; the metal head is combined with the ceramic rod using a dissimilar material welding process, and the bonding surface strength is more than 200MPa, which not only retains the ductility of the metal to buffer the instantaneous impact force, but also improves the resistance to electrochemical corrosion through surface coating technology. The core function of this product is to balance the differences in material properties, not only using the rigidity of ceramics to achieve high-precision motion trajectory control, but also relying on the toughness of metals to reduce assembly stress, which is suitable for complex working conditions that require both stability and adaptability.
In the application scenario, the product shows multiple adaptability. In the field of precision machine tools, it can be used as a guide rod for the spindle feed system, reducing motion loss through the low friction coefficient of ceramics and improving the surface finish of the workpiece; in analytical instruments, it acts as a probe carrier for sample detection, using the chemical inertness of ceramics to avoid contamination of the test sample; in high-end valve devices, it serves as a valve core adjustment component, relying on the sealing performance of the metal head and the medium resistance of the ceramic rod to achieve precise flow control of corrosive fluids, meeting the stringent operating standards of the chemical, pharmaceutical and other industries.
