Reactive Electric Spark Deposition of Ti(CN)–Based Ceramics Coating on Titanium Alloy Substrate

Abstract:

Article Preview

Ti(CN) -based ceramics coating was deposited on TC4 titanium alloy substrate using the home- made reactive electric spark deposition system, which is under nitrogen-sealed atmosphere and using the graphite electrode. It was showed that: (1) the single-pulse deposition zone presents irregular spattering shape and the phase of coatings was made up of TiC0.51N0.12 spherocrystal and dendritic crystal, Ti0.80V0.20 and C, (2) metallurgical bond between coating and substrate is realized, (3) the Ti(CN) ceramic particle, whose average grain size is 626nm, distributes dispersively among the coating and is in-situ synthesized by the reaction among titanium from the substrate, carbon from the graphite electrode and nitrogen from the shielding nitrogen gas.
