[ 1 ] - EFFECTS OF TEMPERATURE AND AL-CONCENTRATION ON FORMATION MECHANISM OF AN ALUMINIDE COATING APPLIED ON SUPER ALLOY IN738LC THROUGH A SINGLE-STEP HIGH ACTIVITYGAS DIFFUSION PROCESS

Abstract: activity gas diffusion process has been investigated in this research. Effects of coating temperature and aluminumconcentration in powder mixture on formation mechanism were studied using optical and scanning electronmicroscopes, EDS and X-ray diffraction (XRD) techniques. For this purpose two different packs containing 1 and 2wt% aluminum powder, were used for coating the samples at ...
