Low pressure cold spray coating of Ti-6Al-4V with SiC-based cermet
The possibility of using the low pressure cold spray system to deposit SiC-based cermet on Ti-6Al-4V was investigated at 0.99 Mpa for 450, 500 and 550°C. The characterizations of the coatings reveal that the initial phases in the feedstock powder were retained in the coatings. No detrimental phase t...

| description | The possibility of using the low pressure cold spray system to deposit SiC-based cermet on Ti-6Al-4V was investigated at 0.99 Mpa for 450, 500 and 550°C. The characterizations of the coatings reveal that the initial phases in the feedstock powder were retained in the coatings. No detrimental phase transformation, decomposition and/or decarburization of the SiC. There was peak shift between the phases of the feedstock powder and that of the coatings. This is traced to impact-induced micro-straining, amorphization and grain refinement. Low pressure cold spray coating of Ti-6Al-4V with SiC-based cermet is plausible with partially homogenous distribution of the SiC, minimal porosity and improved micro-hardness value (approx 652±12.7 HV0.3) in the coating.
