Abstract
This article presents the results of the effect of Supersonic Cold Gas Spraying parameters (variable pre-chamber gas temperature and gas pressure, while the traverse velocity and distance between substrates and nozzles were constant) on wear resistance, microstructure, chemical and phase composition, as well as microhardness of Ti/TiC coatings. Nanostructured powder containing of a varied mixture of Ti and TiC particles has been produced by high energy ball milling. The experiments revealed a strong effect of the deposition parameters and chemical composition of the powders on the structural characteristics of these sprayed cermets. These cermets are made up of two phases (Ti alpha and TiC) as revealed by electron microscopy and X-ray diffraction. Nanostructure was preserved from the powder to the coating. It is demonstrated that it is possible to fabricate the nano-structured Ti-TiC coatings with low porosity and relatively high hardness (similar to 860 HK) by cold spray deposition. The friction and wear behavior of these nanostructured sprayed cermets were compared to the ones of benchmark materials. It was found that the cermet coatings, due to an appropriate balance of hard and soft nano-phases, exhibit better tribological properties than the benchmark materials due to an appropriate balance of hard and soft nano-phases.
