Electrodes for manual arc overlay welding with coating containing nanomodifier TiN in concentrations between 0.2% and 1.5% were developed and manufactured. Samples of welded overlay layers with electrodes were both examined by electron microscopy and X-ray microanalysis. Some samples were subjected to heat treatment consisting of annealing and subsequent hardening in water and oil. The Vickers hardness HV_15/15 of the samples in the prepared state, and both after annealing and hardening were measured. It was found that growth of the hardness of nanomodified layers were up to 180 percent compared to the reference sample.
