Özet
This study investigated the effect of powder-pack boronizing on the microstructure, hardness, and wear and corrosion behavior of AISI 304L austenitic stainless steel. Powder-pack boronizing was carried out using Baybora-1 boronizing agent for 2, 4, 6, and 8 h at 950 degrees C. Boronized AISI 304L steel exhibited a flatter and thinner morphology depending on the alloying elements. XRD analysis showed the presence of CrB, Cr2B, Ni2B, Ni3B, alpha-Mn, MnB, and alpha-SiO2 phases in addition to FeB and Fe2B. Boronizing time increased the boride layer thickness from 20.6 to 50.6 mu m. The highest Vickers microhardness value of 1316.1 HV0.1 was observed in the sample boronized for 2 h. In the wear tests applied with 80, 220, and 400 mesh Al2O3 abrasives under 10, 20, and 30 N loads, the boronized samples exhibited approximately 1.7-10 times more wear resistance than non-boronized steel. In the corrosion test performed in 10% H2SO4 acid solution, corrosion resistance increased with metal boride layer thickness. The sample boronized for 2 h was seen to have the lowest weight loss.
