Abstract
Using scanning tunneling microscopy, it is shown that a lath structure is formed in the heat-affected zone of the low-carbon, low-alloy 09G2S steel after electric arc surfacing. Analysis of the results of scanning tunneling microscopy revealed a number of subtle morphological features of the lath structure, which makes it possible to explain the mechanism of its formation and identify it as lower bainite. The lower bainite structure in the heat-affected zone of the base metal of the 09G2S steel is favourable for increasing the impact strength of the coating – base metal composition, which was established earlier in our work.
