Abstract :

Today’s technology requires creating high-value improvement and treatment, not from cost reduction alone, but from high
levels of skills in maximum integrity, quick production with less waste, density, surface quality and short time.This study
contains cladding two steps process on TiC-X nanocomposites coating in-situ by laser on the substrate in a controlled manner
without using the powder nuzzle.The following are listed some of the advantages for this manner such fullyfused coating to
the substrate with little/no porosity, minimal heat input results in narrow heat affected zone, minimal heat input also results
in limited distortion of the substrate and reduces the need for additional corrective machining and easy, fast and green peace
to automate production. A homogenous combination of a polymer as chemical adhesive, and the Ti, C and X powder particles
causes sufficient adhesion of the powders mixed on the substrate while inert gas flows upon the substrate surface during the
laser cladding process using an easy setup. Consequently, necessity of using powder nozzle can be eliminated without worrying.
Using the inert gas is well able to prevent oxidation of the TiC-X nanocomposite coating at high temperatures. This approach can
identify the reliable uniform and high quality nano-compositions coating during reinforcing TiC nanosized particles with insitu
formed X matrix. So, the hardness optimization of the group of nanocomposites with minimum fluctuation of distributions
while wear rate ratio of the TiC reinforced X-based matrix nanocomposite to the substrate very less than one is sufficiently
achieved.
