Abstract

  Nowadays, there is considerable attention to use of Ni-base COATINGs on steel because of its high CORROSION resistance in various corrosive environments; there is still a considerable void in our knowledge of the influences of additives on CORROSION and microstructure of these COATINGs. Besides, using of Ni-base PACK CEMENTATION method has been very attractive because of its low-cost and ability to coat complex shapes and even the internal surfaces of the samples. For these purposes various amounts of CeO2 (1wt%, 3wt% and 5wt%) was added to the Ni-base (NiCrBSi)(56% Ni, 24% Cr, 7.5% C, 4.5% Fe, 4.5% Si, 3.5% B) raw materials. The PACK CEMENTATION COATING method were used on a mild steel substrate. SEM, XRD, optical microscopy and X-ray diffraction analysis methods were used to characterize the coats. Moreover polarization dynamics CORROSION test was also used to study of CORROSION in a 3.5%t NaCl solution. The results showed that Ni-base PACK CEMENTATION coats are more CORROSION resistance. Besides, the CORROSION rates were decreased with increasing the CeO2 contents in the coat. By comparing the percent inhibition of samples coat a sample of 5% cerium cementation found that the criterion of 86% is the maximum percent inhibition.
