Abstract

The aluminized coating on the X2CrNi19-11 austenitic stainless steel was produced by a pack cementation method at 1000 °C for 4 hours. For aluminizing process the following mixture of powders was used: aluminum in the form of fine powder applied to the substrate surface, AlCl3 as an activator and corundum (-Al2O3) as an inert filler in powder form to prevent sintering of powder mixtures at high temperatures. Aluminized sample was annealed in two 60-minutes cycles at 700 °C in oxidizing atmosphere. Microhardness HV 0.025 of bulk material and the aluminized coating was measured after aluminization and oxidation. Optical microscopy was used to investigate the microstructure and to measure the thickness of the coatings.
