“…What is in correlation with previous findings is the friction level for saline solution. In a recent study [ 23 ], a polyethylene disc conducted reciprocating motion against a metal pin (pure positive sliding), while the friction was from 0.12 to 0.16, which corresponds to the present results, see Figure 7 b.…”

The paper introduces an experimental investigation of frictional behaviour of materials used for joint replacements. The measurements were performed using a ball-on-disc tribometer, while four material combinations were tested; metal-on-metal, ceramic-on-ceramic, metal-on-polyethylene, and ceramic-on-polyethylene, respectively. The contact was lubricated by pure saline and various protein solutions. The experiments were realized at two mean speeds equal to 5.7 mm/s and 22 mm/s and two slide-to-roll ratios, −150% and 150%. It was found that the implant material is the fundamental parameter affecting friction. In general, the metal pair exhibited approximately two times higher friction compared to the ceramic. In particular, the friction in the case of the metal varied between 0.3 and 0.6 while the ceramic pair exhibited friction within the range from 0.15 to 0.3 at the end of the test. The lowest friction was observed for polyethylene while it decreased to 0.05 under some conditions. It can be also concluded that adding proteins to the lubricant has a positive impact on friction in the case of hard-on-hard pairs. For hard-on-soft pairs, no substantial influence of proteins was observed. The effect of kinematic conditions was found to be negligible in most cases.

“…Ancak Guezmil vd. UHMWPE' in tribolojik özelliklerini inceledikleri çalışmalarında oluşan debrislerin karşı malzemeye taşınmasından dolayı test sırasında oluşan çatlaklara ortaya çıkan debrislerin yerleştiği ve bu sonuçların kuru aşınmada ortaya çıkan sıcaklık artışı ile oluşan plastik deformasyon ile de ilgisi olduğunu aşınma bölgesi görüntüleri ile de göstermişlerdir [17]. Bu çalışmada saf su ortamında kompozit örneğinin daha fazla yorulma aşınmasına uğradığını gösteren çatlağın büyüklüğü, test sırasında örnek üzerinde saf su filminin zarar görmesinden ziyade, aşınma testi sırasında karşı malzemeye yapışan debrislerin oluşan çatlağa dolmasından kaynaklanmakta olduğu düşünülmektedir.…”

Ultra yüksek moleküler ağırlıklı polietilen (UHMWPE), biyo-uyumluluğu ve mükemmel özellikleri nedeniyle kalça ve diz protezleri için en uygun malzemedir. Bu çalışmada, düşük yoğunluğa ve yağlayıcı özelliğe sahip olan grafen dolgu maddesi olarak kullanılmış ve kompozitin performansını güçlendirmek için UHMWPE matrisine ilave edilmiştir. Saf UHMWPE ve ağırlıkça % 0,5 indirgenmiş grafen oksit (CRGO) dolgulu kompozitin (CRGO / UHMWPE) aşınma davranışları kuru ve sulu ortamlarda incelenmiştir. UHMWPE ve CRGO sıvı faz ultrasonik dispersiyon ile karıştırıldıktan sonra kompozit örnekleri sıcak pres kalıplama ile üretilmiştir. FTIR analiz sonuçları, dolgu maddesi ile polimer matrisi arasında etkileşim olduğunu, XRD analizi UHMWPE' nin kristali yapısında meydana gelen değişimi, SEM-EDS elementel haritalama analizi sonuçları ise oksijenin polimer matrikste homojen bir şekilde dağıldığını göstermiştir. Kompozit örneğinin sürtünme katsayısı ve aşınma hızı değerleri CRGO ilavesiyle hem kuru hem de sulu ortamda azalmıştır. Çünkü hem grafen hem de saf suyun yağlayıcı özelliği, kompozit örneğinin sürtünme ve aşınma davranışını önemli ölçüde etkilemiştir. Kompozit numune için kuru kayma koşullarında plastik deformasyon ve yorulma aşınması baskınken, sulu ortamda adhezif aşınma izleri gözlenmiştir.

“…Being a well-known engineering thermoplastics, ultrahigh molecular weight polyethylene (UHMWPE) has the advantages of low friction coefficient, superior wear resistance, good biocompatibility, high chemical stability, and good mechanical properties [17,18]. Because of the prominent wear resistance, UHMWPE has been widely studied and applied in biotribology fields [19][20][21], and also shows the great practical potency in water-lubricated bearings [22]. However, the limitations caused by the low viscosity of water still exist and result in the degradation of the lubricating performance of UHMWPE.…”

Designing soft/hard double network hydrogel microsphere/UHMWPE composites to promote water lubrication performance

Several soft tissues residing in the living body have excellent hydration lubrication properties and can provide effective protection during relative motion. In order to apply this advantage of soft matters in practical applications and try to avoid its disadvantage, such as swelling and weakening in water, a design strategy of a soft/hard double network (DN) hydrogel microsphere modified ultrahigh molecular weight polyethylene (UHMWPE) composite is proposed in this study. A series of microspheres of urea-formaldehyde (UF), polyacrylamide (PAAm) hydrogel, UF/PAAm double network, and their composites were prepared. The mechanical properties, swelling, wettability, friction properties, and the lubrication mechanisms of the composites were investigated. The results show that DN microspheres can have an excellent stability and provide hydration lubrication. The performance of 75 DN-1 composite was superior to others. This finding will provide a novel strategy for the development of water-lubricated materials and have wide application in engineering fields.
