Technical difficulties of ceramic hip joint manufacturing
The latest generation of alumina toughened zirconia composite ceramic hip joint ball, one stroke optimization of the first three generations of hip joint ball, making it the most suitable hip joint material products, due to its material performance superiority and stability, raw material manufacturing process has high technical barriers, in addition to ceramic material brittleness, fracture toughness is low, machining technology is difficult, complex process, Artificial joint ceramic ball head and lining manufacturing for hardness, toughness, finish, precision have a high demand, so in the raw material end and machining end, the upstream of the ceramic joint has been foreign monopoly, a monopoly, is the key to the entire artificial joint industry want to break through, but has been unable to overcome the material performance.
Factors of raw materials:
A. the proportion of components in the material requires high precision;
B. the size uniformity of each component of the mixed slurry is difficult;
C. the moisture uniformity control requirements of slurry drying are high.一
Factors of machining:
The corresponding special equipment development will be a difficult problem, especially its outer spherical roundness 0.005 and roughness level Ra0.02, metal Ra0.1 is already mirror level, ceramic to reach Ra0.02, on the other hand, its inner hole Angle matching tolerance is ±0.042° and straightness 0.003 and roundness 0.008 multiple constraints, It makes the processing more difficult, so the accuracy and stability of the equipment used are extremely high, and the other is the detection problem. The current detection equipment is high-precision Zeiss trilinear coordinates measuring instrument, and the accuracy should reach 0.7um level or above.
