AI Technical Summary
Existing surface treatment processes for zirconia ceramic bearing assemblies are difficult to achieve a synergistic improvement in ultra-cleanliness and high biocompatibility, and are highly dependent on equipment, failing to meet the requirements of high cleanliness, non-cytotoxicity, and sterilization resistance for cell mixing bags.
Introducing bioactive microparticles into the plasma treatment process, combined with physical ultrasound and gentle chemical cleaning, utilizes plasma energy to achieve a synergistic effect of etching and cleaning with microparticle activation and deposition, reducing reliance on high-precision specialized equipment.
It achieves a synergistic improvement in the ultra-cleanliness and high biocompatibility of ceramic bearing components, making it suitable for small and medium-scale production, reducing equipment procurement and maintenance costs, and achieving a high product qualification rate, thus meeting the requirements for use in cell mixing bags.
