Electric arc spraying is a promising technique for enhancing the wear resistance of components operating under abrasive and mechanical loads, particularly in agricultural soil-processing machinery. This study aims to comparatively analyze the properties of coatings formed using electric arc metallization with cored and solid wires of 30KhGSA and 51KhFA steel grades. Experimental investigations were carried out to evaluate the influence of wire type on the microstructure, microhardness, adhesion strength, and wear resistance of the sprayed coatings. Metallographic analysis and microhardness measurements revealed that coatings produced with cored wire exhibited a finer lamellar structure and higher hardness values compared to those formed with solid wire. Wear tests demonstrated improved resistance under abrasive conditions for cored wire coatings, indicating better performance under operational loads. The optimized spraying parameters were determined to ensure uniform and adherent coatings. The results suggest that using cored wire in electric arc spraying offers significant advantages in forming high-quality protective layers. These findings support the potential application of the developed coatings in extending the service life of soil-engaging machine parts under intensive field conditions.
