Friction and Wear Behavior of Boronized Chromium for Biological Applications

Enhanced corrosion and wear resistance are crucially important to prolong the service life of biomaterials. Boronizing has been reported to enhance the wear resistance of pure chromium. In this research, we investigate friction and wear behavior of boronized chromium. Pin-on-disc tribometer was used to conduct the wear and friction tests. Experiments were conducted in dry conditions as well as in simulated body fluid (SBF). Fundamental aspects of wear mode and lubrication behavior were studied using surface characterization techniques such as TEM, and X-ray diffraction. Results showed evidence of tribo-chemical interactions between SBF and work piece materials.
