alloy exhibited the highest corrosion rates of 432 μm/y as measured by electrochemical testing and 57.9 μm/y as measured by immersion testing. The as-cast Zn–xTi alloys showed lower wear losses than...Binary Zn–Ti alloys for orthopedic applications: Corrosion and degradation behaviors, friction and wear performance, and cytotoxicityKun Wang1,2,Xian Tong3,1,Jixing Lin1,Aiping Wei1,Yuncang......
/min. To prepare the wear samples, the tested wear surfaces of samples were polished to remove their oxidation surfaces. The dry sliding wear tests were conducted on a pin-on-disc wear testing machine... composites with different SiO2/C/Al molar ratios were fabricated by reaction hot pressing. The dry sliding wear characteristics of the composites were investigated using a pin-on-disc wear tester......
