Development and Testing of Materials with Reduced Wear by Fixed Abrasive

Abstract:

Abrasive wear into embedded abrasive (Al₂O3) of Fe–C–Si–Mn–Cr–B layers welded by an electric arc has been studied. The amounts of carbon (0.45–2.92%), chromium (1.1–18.7%) and hardness (73–82 HRA) of welded layers have no impact on wear. Due to great differences in hardness of welded layers and abrasive, the metal surfaces are intensively wearing due to microcutting. It is determined that the harder the layers, the greater their resistance to wear. Alloying of a medium content carbon layer (0.45% C) with boron of 0.51% reduces the wear up to 27%. Minimal amounts of carbon 0.45%, chromium 1.1%, boron 0.5% guarantee stable and high resistance of welded layers to wear.
