“…the CoCr was unaffected. The actual 'roughening' mechanism appeared to be the transient transfer layers of PMMA onto the counterfaces and the accelerated wear came from 2-body abrasion between PMMA and CXPE surfaces [17,18]. Our duplication of the PMMA studies by Dr. Wang supported these conclusions and while different types of PMMA debris were used, there was agreement that the PMMA did not adversely affect CoCr roughness [29].…”

“…Thus it is universally accepted that wear will be exacerbated by increased surface roughness of the CoCr counterfaces [3,11,[15][16][17][18][19][20][21][22]24,28]. 3rd-Body particles may include CoCr, Ti64, bone cement (PMMA) and hydroxyapatite, all used as implant coatings to facilitate biological attachment in various implant designs [25,31].…”

“…However one laboratory study indicated an unexpected type of roughening mechanism. Using lubricant slurries loaded with particles of polymethyl-methacrylate (PMMA: bone cement used to fix implants), it was noted that CXPE wear doubled with a PMMA concentration of 5 mg/ml compared to 1 mg/ml and then quadrupled with a concentration of 10 mg/ml [17]. The authors noted that the increased wear did not result from an increase in counterface roughness, i.e.…”

“…However, with wear rates as high as 1000 mm 3 per million load cycles (1 Mc), this may have represented a non-physiological 3rd-body wear PMMA concentration model (10 mg/ml slurry). Therefore our goal was to repeat the study using a 5 mg/ml concentration of slurry and also contrast the relative performance of CoCr to Al 2 O 3 counterfaces [17].…”

“…Despite this, the values presented can be used for relative comparisons within the study and the C concentrations correlate well with what was expected from the deposition rates from the targets. For hip joints there is a risk that wear particles or bone cement particles become trapped in the contact and cause abrasion (Bragdon et al, 2003;Dowling et al, 1978 ;Wang and Essner, 2001). A higher hardness of the joint bearing surfaces could therefore be an advantage by increasing the resistance to two and three body abrasive wear.…”

Total joint replacements currently have relatively high success rates at 10–15 years; however, increasing ageing and an active population places higher demands on the longevity of the implants. A wear resistant configuration with wear particles that resorb in vivo can potentially increase the lifetime of an implant. In this study, silicon nitride (SixNy) and silicon carbon nitride (SixCyNz) coatings were produced for this purpose using reactive high power impulse magnetron sputtering (HiPIMS). The coatings are intended for hard bearing surfaces on implants. Hardness and elastic modulus of the coatings were evaluated by nanoindentation, cohesive, and adhesive properties were assessed by micro-scratching and the tribological performance was investigated in a ball-on-disc setup run in a serum solution. The majority of the SixNy coatings showed a hardness close to that of sintered silicon nitride (∼18 GPa), and an elastic modulus close to that of cobalt chromium (∼200 GPa). Furthermore, all except one of the SixNy coatings offered a wear resistance similar to that of bulk silicon nitride and significantly higher than that of cobalt chromium. In contrast, the SixCyNz coatings did not show as high level of wear resistance.

Clinical and in vitro studies on ceramic hip prostheses correlate cup implant position with hip noise, ceramic wear, or ceramic liner damage. A ceramic cup malposition could lead to edge load, ceramic head wear, and squeaking. A noise of a ceramic hip could also be correlate with implant instability and liner damage. Aim of this study was to investigate the long-term wear behavior of 12 commercial alumina-on-alumina bearings under severe conditions: different angles of inclination (23 degrees, 45 degrees, and 63 degrees) and the addition of third body particles (titanium and alumina powder) to address the effective role of cup position and ceramic particles on wear and hip noise. The study was performed using a 12-stations hip joint wear simulator (Shore Western, Monrovia) under bovine calf serum used as lubricant. Wear was evaluated by gravimetric method and the piezo-spectroscopic technique was used to evaluate the residual stress of the ceramic components and correlate this to the weight loss. After eight million cycles, we found that the inclination of the cup (63 degrees in this study) was the most disadvantaged and it was correlated with a hip noise. Gravimetric measurements showed higher wear than the other configurations and these results were in agreement with the Photoluminescence investigation. In particular, the results obtained in this work revealed a residual stress state greater not only with respect to the other angles of inclination but also to two retrieved alumina acetabular cups with a 10 years follow-up.
