Abstract
Laser cladding, which is characterized by the minimal thermal impact on the substrate, is an advanced technique to restore the working dimensions of parts subject to wear. The Ni–Cr–B–Si system coatings can be used for parts operating at high temperatures. Our work aims at studying the effect of heating and subsequent cooling conditions in the process of high-temperature treatment on the features of the structural and phase state of the coating obtained by laser cladding of the PG-SR2 powder (chemical composition, wt %: 14.8 Cr, 2.1 B, 2.9 Si, 2.6 Fe, and 0.48 S; the rest is Ni) and the properties obtained as a result of this treatment (hardness and tribological characteristics in sliding on fixed abrasive corundum). Samples with a laser-clad layer were heated at a temperature of 1050°C (holding for 1 h) and subsequently cooled in water (which made it possible to record structural transformations under high-temperature heating), in air, and in a muffle and a vacuum furnace. It has been shown that the rate of cooling during the high-temperature treatment of the laser-clad PG-SR2 coating significantly affects the structure and properties. High-temperature heating leads to partial diffusive dissolution of nickel borides (Ni3B) and chromium carbides (Cr23C6) in a solid solution and a corresponding decrease in hardness and an increase in the abrasive wear intensity and the coefficient of friction. The reduction in the rate of cooling from 1050°C of the samples in air, a muffle furnace, or a vacuum furnace leads to the precipitation of chromium borides (CrB) and nickel silicide (Ni3Si), which were absent in the clad coating structure. High-strength CrB borides whose hardness is equal to or even exceeds that corundum abrasive hinder the development of the microcutting mechanism in the process of abrasive wear. Coarse chromium carbides and borides formed in the process of slow cooling in the furnace form wear-resistant framelike structures. This results in an increase in hardness and abrasive wear resistance to the values that exceed those of the original clad coating.
