“…In general, boron additions to the mixtures resulted in increments of between 1.86 and 3.09 GPa in the maximum microhardness values ( Figure 6, Table 3). The maximum microhardness values of the chrome-boronizing-siliconizing coatings are similar to those reported by Chen et al 16 for a multi-components layer (chrome-boronizing-siliconizing, mixtures h and g) on medium-carbon steel. Also, they are higher than those obtained in previous works for chromizing layers 30 .…”

The chromium carbide coatings are widely used in the mechanical industry due to its corrosion resistance and mechanical properties. In this work, we evaluated a new source of chromium and silicon with micro-additions of boron on the deposition of multi-component coatings of chromium carbides in W108 steel. The coatings were obtained by the pack cementation method, using a simultaneous deposition at 1000 o C for 4h. The coatings were analyzed by X-ray diffraction, X-ray energy dispersive spectroscopy, optical microscopy, microhardness test method and pin-on-disc wear test. It was found that the coatings formed on W108 steel were mainly constituted by (Cr,Fe) 23 C 6 , (Cr,Fe) 7 C 3 , Cr 5-x Si 3-x C x+z , Cr 3 B 0,44 C 1,4 and (or) Cr 7 BC 4 . The carbide layers showed thicknesses between 14 and 15 µm and maximum values of microhardness between 15.8 and 18.8 GPa. Also, the micro-additions of boron to the mixtures showed statistically significant influence on the thickness, microhardness and abrasive wear resistance of the carbide coatings.

We report the in situ synthesis of a dense TiC ceramic layer between a titanium plate and graphite flakes in gray cast iron using heat treatment. The phases of the dense ceramic layer were determined by XRD, and the microstructures of the layer were characterized by SEM. The kinetics of the layer were also analyzed. The particle sizes of the as-prepared TiC samples varied from 1 mm to 10 mm. The thicknesses (d) of the layers, which increased gradually with incubation time, were 46, 65, 80, 96, and 110 mm after 1, 2, 3, 4, and 5 h of incubation at 1433 K, respectively. The formation of the dense layer involves diffusion, an in situ reaction, and the diffusion of C, Ti, and TiC atoms. The d of the layer changed parabolically with time, and the relationships between d, T, and t were determined.
