In this research, we studied the wear and diffusion behavior of two MoB/CoCr and MoB/CoTi coatings cladded on the 316L substrate. The morphology and chemical composition of the coating and base metal were investigated by optical microscopy, electron microscopy and X-ray diffraction analysis. It was found that both coatings contain boride and metal compounds. MoB/CoCr coatings contain tighter phases and a subtle structure, which is why it shows a higher degree of hardness. The hot-cycle corrosion test of samples at 900 ° C showed that by applying this two coatings, both samples were sharply reduced. The wear test was performed at ambient temperature and temperature of 500 ° C by means of pin on disk in 3 different forces. It was found that the wear mechanism of the coated and non-coated samples varies in ambient temperature and high temperature. At high temperatures due to oxidation, the samples exhibit better wear resistance and in general MoB/CoCr coating showed the best wear resistance. Samples were immersed in the melted zinc in 500° C for 6, 12 and 24 hours. Unlike the uncoated sample, after 24 hours, no effect of zinc penetration was observed on the coated samples.
