*2.5. Abrasion Resistant Layer Formed by GMA with Ceramo-Metallic Wire*

The abrasion-resistant layer was made by single-layer GMA welding of 15 HM steel using a ceramo-metallic wire with a 50% nickel carbide content of tungsten carbide (WC). The analysis of the chemical composition is shown in Table 5.
