Abrasive and impact-abrasive wear resistance of solid weld deposits

Machinery mining machines and metallurgical equipment fail due to abrasion during operation. Wear and tear causes the working surfaces to be reconstructed, which means costs and the increase of machine price. Therefore, the development of materials and technologies that will significantly increase the wear resistance of these parts without significant costs is an important task. The most promising here is the use of plasma-powder surfacing for wearing surface details. To fulfill the task a special surfacing powder, which is a high-carbon alloy of eutectic composition, was created. Due to optimal alloy building deposited coatings have high values of hardness, abrasion and impact-abrasive wear resistance. Moreover, the increase of wear resistance during surfacing by the proposed powder resulted from the refinement of the structure and from the orientation of its growth in the direction of force application.
