Abstract
The wear-resistant layers of the chromium cast iron structure can be made by traditional casting methods as well as by the use of welding methods. The use of hardfacing allows for the creation of a protective layer on existing elements, often in the place of their use. Especially the use of hardfacing using self-shielding core wires allows obtaining layers with the desired properties. The paper presents the results of research on high-chromium hardfacings made in self-protective technology as well as using shielding gas. It was noted that the addition of shielding gas has a positive effect on the stability of the surfacing process and on the appearance of hardfaced surfaces. The hardness tests and erosive wear tests carried out also indicate a positive effect of shielding gas on the properties of hardfacings.
