The invention discloses an aluminum-based B4C-ceramic-contained electric arc spraying powder core wire material, and belongs to the field of material processing surface engineering. The melting pointof the B4C ceramic is up to 2350 DEG C, the vickers hardness is about 55-67 GPa, and the excellent chemical stability is achieved. According to the aluminum-based B4C-ceramic-contained electric arc spraying powder core wire material, the powder core of the wire material comprises the following components of, by mass, 1-5% of 250-300 micron B4C powder, 60-80% of 50-200 micron B4C powder, 10-20% of10-45 micron B4C powder and 5-19% of aluminum powder; a 5052 semi-hard aluminum strip is adopted to wrap the flux core powder, the filling rate of the powder core is 28-32%; and a prepared coating hasno obvious defects, the average microhardness of a B4C ceramic particle in the coating is 5000 HV or above, the friction abrasion performance of the coating is obviously superior to that of a pure aluminum coating.
