WebOct 6, 2013 · Counterface samples of 15 × 4 × 1 mm 3 in size replicating 12 surfaces of different isotropic roughness (figure 1 b–d and table 1) were cast out of 2 Ton Clear Weld Epoxy, (ITW Devcon, Riviera Beach, FL, USA) using a two-step moulding technique . This helped studying the effect of surface topography only, while avoiding introduction of ... WebMay 1, 1996 · The effect of counterface selection on the tribological performance of a Ag/BaF{sub 2}-CaF{sub 2} containing composite coating is studied. Ceramic (Al{sub 2}O{sub 3}) and metal (Inconel X-750) pins are slid against PS300 (a metal bonded chrome oxide coating with Ag and BaF{sub 2}/CaF{sub 2} lubricant additives) in a pin-on-disk …

Web3.3. Study 3: influence of counterface arrangement. The effect of counterface arrangement was explored by using PEEK, CFR-PEEK and GUR1020 UHMWPE plates articulating with CoCrMo pins with a curved counterface of 35 mm radius. A curved pin surface was used to reduce the edge-effect of a metallic pin articulating with a polymer plate. WebThe counterface topographies of the wear plates were produced using techniques representative of current manufacturing methods. The surface roughness of the wear plates was varied in the range Ra = 0.005-0.04 micron; this was representative of femoral heads and femoral knee components currently used clinically. emmaus christian fellowship chorley
