Abstract:

The paper presents investigation of methods of injecting of nanocomponents into the welding pool, that are adapted for surfacing processes. They differ by form and way of injecting. A mixture of nanopowder with flux, spray technology, a mixture with alcohol and a paraffin rod were tested during research. Silicon oxide nanopowder and carbon fiber have shown a positive effect on the durability. Positive changes in the structure of weld metal and microhardness increase were detected when using nanocomponents. To assess the role of non-metallic inclusions on the structure of the surface, welds were examined for their chemical composition, dimensions and density of precipitates in a metal matrix. Statistical analysis of non-metallic inclusions in the weld metal was done. It has shown that cumulant coefficients and probability density functions of diameters of equivalent circles of non-metallic inclusions are sensitive to various types of additives in steel.
