Effect of mechanical activation of ultrahigh molecular weight polyethylene on its mechanical and tribological properties
The effect of the mechanical activation of original powders of ultrahigh molecular weight polyethylene on its physical-mechanical properties is studied. It is found that mechanical activation improves strength and tribological characteristics of ultrahigh molecular weight polyethylene. Methods of X-ray structure analysis, IR spectroscopy and optical and electron microscopy have revealed that the mechanical activation of the original powder governs the structure organization of the polymer
