CORROSIVE WEAR OF CARBON AND AUSTENITIC STAINLESS-STEELS IN NACL SOLUTION

The wear rates of AISI 52100 carbon steel and type 316 austenitic stainless steel and the corrosion current I from the rubbing steels were measured in a NaCl solution to study the interrelationship between the corrosion and wear of the steels. An on-off cyclic loading test was also conducted to examine the effect of static corrosion during the unloading period on the corrosive wear of the steels. It was found that the wear rates of the carbon steel and type 316 stainless steel reach a maximum at NaCl concentrations of about 3% and 0. 1%, respectively. The on-off cyclic test has shown that corrosive wear of the steels is influenced by static corrosion during the unloading period. The increment DELTA I of the corrosion current due to sliding was associated with the corrosive wear rate of the steels.
