Features of changing the mechanical properties of the area of abrasion-resistant surfacing on heat-strengthened steel
New dependencies and relationships were identified for the first time after the implementation of abrasion-resistant surfacing technology on heat-strengthened steel 65G. This technology revealed the nature of the Vickers hardness distribution in the vertical and horizontal directions of the surfacing area and demonstrated their identity. It has been established that the thermal effects from the welding arc reduce the hardness of the base metal located directly in the lower part of the surfacing area. Compared with the planar direction, the thermal influences on metal hardness, size of the thermal influence zone, and the heat-affected zone are more pronounced in the depth of the surfacing area. This study clarifies the changes in HV hardness in various zones is provided based on recent studies in materials science and metallurgy.
