Wear Resistance of Hypereutectoid Steel Alloyed with Copper and Aluminum

Abstract:

The structure, mechanical properties and wear resistance of hypereutectoid steel containing 0.09-8.97 wt. %copper were studied. It is found that an increase in copper increases lamellar pearlite microhardness. Triboengineering testings under conditions of sliding friction show that wear resistance of hypereutectoid steel alloyed with 8.97 wt. % copper is ~3.5 times higher than the wear resistance of bronze and by ~23 % higher than the wear resistance of bearing cast iron. Under conditions of friction on fixed abrasive particles a relative wear resistance of the hypereutectoid steel alloyed with copper is ~3 times higher than a relative wear resistance of bronze.
