Reaction Spray by Laser-Plasma Jet : Synthesis of TiN Coatings(Physics, Process, Instruments & Measurements)
Search this Article
The synthesis of TiN coating has been investigated with using the laser-plasma spraying, Ti sprayed coating was formed by N_2 plasma jet, and it was irradiated with CO_2 laser beam in a low pressure nitrogen atmosphere. Main results obtained was summarized as follows: Ti sprayed coating can be more nitrized with irradiation of CO_2 laser in N_2 atmosphere, and the nitridation degree of the Ti sprayed coating was increased with the increasing of the laser output and number of the laser irradiation times. The hardness of the TiN coating obtaied was about 1300HV.
