N2 - Some mechanical properties of AISI 1045 bonded steels were estimated in the present work. The bonding process was carried out by the powder pack method at 950°C with 8 h of treatment. The fatigue strength on bonded notched specimens was evaluated with rotating bending tests (R=1) considering a stress concentration factor (Kt) of 2.53. Likewise, the presence of residual stresses in boride layers was established by the XRD technique. The Daimler-Benz Rockwell C test was used, also, to estimate the strength adhesion of the coated system. The results show a decrease in the fatigue strength of AISI bonded steels due to the presence of high porosity in the layers. Finally, the Rockwell-C adhesion test showed no coating failure for the boride layer.
