Improvements of Wear Properties DLC Coated UHMWPE and PMMA for Biomaterial

Abstract:

Diamond-like carbon (DLC) films were deposited onto UHMWPE and PMMA substrates using plasma CVD process. To improve adhesion of DLC films, substrates were treated plasma before DLC deposition. Samples were analyzed by ball-on disk tester, atomic force microscopy (AFM), and scratch test. Wear and scratch resistance of DLC-coated each substrates were evaluated and showed good results.
