The TiC/Ni functionally gradient coating on H13 steel surface was prepared by self-propagating high temperature synthesis and pseudo hot isostatic pressing（SHS/PHIP）.TiC/Ni functionally gradient coatings were measured in melted aluminum for 0.5 hand 2 hstatic erosion test at 700 ℃.The coating phases after erosion were analyzed by XRD

and the microstructure and composition of the coatings were observed by SEM-EDS.The results show that the main phase of the coating is composed of TiC

Ni

TiO

2

and AlNi

3

.The surface failure of coating is attributed to the corroded Ni binder phase and the oxidized TiC framework.The subsurface failure of coating is mainly caused by the erosion of Ni binder phase

while the TiC framework remains the original structure.The erosion resistance of TiC is better than that of Ni binder phase.
