In this study, TiC particle-dispersed Ti3Al/TiAl matrix ceramic layer on the Ti–6Al–4V alloy by laser cladding has been researched by means of X-ray diffraction, scanning electron microscope, electron probe micro-analyzer, energy dispersive spectrometer. The main difference from the earlier reports is that Ti3Al/TiAl has been chosen as the matrix of the composite coating. The wear resistance of the Al + 30 wt. TiC and the Al + 40 wt. TiC cladding layer was approximately 2 times greater than that of the Ti–6Al–4V substrate due to the reinforcement of the Ti3Al/TiAl + TiC hard phases. However, when the TiC mass percent was above 40 wt., the thermal stress value was greater than the materials yield strength limit in the ceramic layer, the microcrack was present and its wear resistance decreased. date: 2010 date_type: published publication: Applied Surface Science volume: 257 number: 5 publisher: Elsevier pagerange: 1550 - 1555 id_number: 10.1016/j.apsusc.2010.08.094 refereed: TRUE issn: 0169-4332 official_url: http://www.sciencedirect.com/science/article/pii/S0169433210011724 citation: Li, Jianing and Chen, Chuanzhong and Squartini, Tiziano and He, Qingshan A study on wear resistance and microcrack of the Ti3Al/TiAl + TiC ceramic layer deposited by laser cladding on Ti–6Al–4V alloy.
