Paper Title:
Study on Microstructure and Nanotribology Property of Antibacterial Bone China Film
  Abstract

Fracture surface and surface of two kind of membrane of antibacterial bone china, which includes 3% and 5% of weight of composite phosphate containing rare earth respectively, were characterized by SEM and nanoindenter, respectively. Nanohardness and nanoscale friction coefficients were measured by nanoindenter. Friction coefficients were conducted at the maximal load being 300un,500un,1000un and scratching speed 15um/s, 0.75um/s, 0.5um/s, respectively. The nanohardness and friction coefficients of ceramic membrane including 3% and 5% of rare earths are 2.03GPa,0.18282 and 8.54GPa,0.051998, respectively. The two kind of ceramic membrane has stable nanotribology property. Obvious plastic flow and pile-up scratch impression of ceramic membrane including 3% rare earths is observed by AFM in situ imaging, but scratch impression of 5% has no plastic flow and take on the sink-in topography. Nanohardness and friction coefficients of this two kind of ceramic membrane have strong relationships each other but weak relations with elastic modulus.
