Tribocorrosion of Low Carbon Steel C15E in 5 % NaCl and 5 % NaCl + SiO2

The article represents testing results of corrosion and erosion-corrosion wearing. Specimens have been made from low carbon steel C15E in four different states: delivery state and heat-treated (carbonising, boronising and carbonising + boronising). The results are shown as wearing of materials (losing of surface mass in mg/(cm2˙d)). Surface hardness method HV1 and micro hardness per section of specimen HV0, 2 method have been used during the analyses. A comparison of testing results of wearing in four different states was made. The best performances have shown samples which have been treated with duplex procedure (carbonising + boronising) as was predicted.
