Processing of TiC-CNT hybrid composite coating on low alloy steel using TIG Torch technique
In the present study, a surface layer of TiC-CNT hybrid compositecoating has been developed on low alloy steel (LAS) by using powder preplacement and tungsten inert gas (TIG) torch melting techniques.The weighed powder mixture with the content of 1.0 mg per millimeter square area and containing T...

description |
In the present study, a surface layer of TiC-CNT hybrid compositecoating has been
developed on low alloy steel (LAS) by using powder preplacement and tungsten inert gas (TIG)
torch melting techniques.The weighed powder mixture with the content of 1.0 mg per millimeter
square area and containing TiC- 4wt. % CNT particles was preplaced on LAS surfaces using a
suitable binder and then melted under the TIG arc with an operating current of 100 A and energy
input of 1440 J/mm. The microstructural and microhardness characteristics of the processed
composites coating were analyzed using SEM, EDXand Vickers microhardness testers. Under the
melting condition used in this investigation, the arc completely dissolved the composite powder
mixture that resolidifiedinto a melt track with radial marks and smooth surfaces. Themelt cross
sections were hemispherical in shape and produced 1 mm deep hard coating layer which were free
from porosity and cracks. SEM micrographs TiC-CNT hybrid coated surface glazed at 100A
consists of fineprecipitated TiC in form globular and cubic dendrites and this is the reason for
hardness increment to an average of three times greater than that of substrate value. The result
obtained indicated that TIG arc melting process is applicable to generate resolidified layer of
precipitated TiC microstructure with uniformly distribution in the coating region. |
