AB  - Objective: To analyze the wear debris characteristics ofcarbon-based nano- 
      multilayer coatings on Ti(6)Al(4)V alloys and compared with the cobalt chromium 
      molybdenum alloy (CoCrMo) femoral head to evaluate the friction and wear 
      performance of the new coated femoral head. Methods: Three groups were set up in 
      the wear simulation experiment according to the type of femoral head. Group A: 
      imported Cobalt-Chromium-Molybdenum alloy femoral head (CoCrMo); group B: 
      Titanium alloy femoral head (Ti(6)Al(4)V) with carbon-based nano-multilayer 
      coatings; group C: domestic Cobalt-Chromium-Molybdenum alloy femoral head 
      (CoCrMo). All heads were jointed with an ultra-high molecular weight polyethylene 
      (UHMWPE) acetabular cup. Serum samples were collected and stored in the hip joint 
      simulator. After the sample has been digested and diluted, it was filtered 
      through 5 mum, 1.2 mum and 0.4 mum filters, and the filter paper was collected for 
      testing. Scanning electron microscope (SEM) was used to randomly select regions 
      on the filter to obtain images of wear debris. Energy dispersive X-ray 
      spectroscopy (EDS) was used to determine the elemental type of the particle and 
      to eliminate possible contamination. The composition and structure of the 
      abrasive chips were measured using Fourier transform infrared spectrometer 
      (FTIR). The parameters related to the wear debris includingparticle size, shape, 
      number and volume were calculated. The differences in correlation parameters 
      between the groups were compared to evaluate the friction and wear properties of 
      the new coated joints. Results: The main component of the wear debris produced 
      was UHMWPE, and the particle size was mostly below 1 mum. The submicron particle 
      ratio of group B was 49.4%, which was significantly lower than that of the group 
      A and C (75% and 60%, respectively; chi(2)=66.032, 31.754, both P<0.017). The shape 
      was mainly round, and there was no statistical difference between the groups 
      (chi(2)=0.590, P=0.744). The number of particles in group B was significantly less 
      than that of group C on all filters (t=9.960, 8.019, 5.790, all P<0.01), and less 
      than group A on the 0.4 mum filter (t=7.810, P=0.000). Conclusion: The frictional 
      wear performance of the new carbon-based nano-multilayer coatings femoral head is 
      significantly better than that of the domestic femoral head, and even partially 
      exceeds the imported femoral head level, which helps to reduce the production of 
      particles and prevent osteolysis and aseptic loosening induced by UHMWPE 
      particles.
