Rapid Analyses of Polyetheretherketone Wear Characteristics by Accelerated Wear Testing with Microfabricated Surfaces for Artificial Joint Systems

Figure 1

Experimental setup of wear testing. (a) Schematic of the particle generation in which microfabricated surface texture is rubbed against PEEK pin. (b) Schematic of the setup for linear reciprocating wear testing. (c) Schematic of the microfabrication process of surface textures on the silicon wafer. (d) SEM images of the surface S; the wedges are 5 μm in width and 5 μm in length. The textures in the black circle are magnified on the right. (e) SEM images of the surface L; the wedges are 5 μm in width and 10 μm in length. The textures in the black circle are magnified on the right.
