The invention discloses a method of adding nanocarbon tubes to prepare a laser light gradient composite material. The method comprises the following steps: mixing Ni60A-TiB2-CNTs-Cu with Ni60A-TiB2-Cu according to a certain mass ratio, and uniformly blending the mixed powder with a sodium silicate solution to be pasty; uniformly coating a titanium alloy surface with the pasty mixed powder, wherein the coating thickness is 0.1-2 mm, and naturally airing; after the airing, uniformly coating an Ni60A-TiB2-CNTs-Cu preset layer with the Ni60A-TiB2-Cu pasty mixed powder; performing laser cladding treatment on a titanium alloy specimen, wherein the technological parameters are as follows: the laser power is 0.20-4.50 kW, the spot diameter is 0.5-10 mm, the scanning speed is 1-25 mm/s, and the multichannel overlap rate is 35%, and the whole testing process is carried out in an argon shielding box. The method disclosed by the invention can be used for obtaining the gradient composite material with strong stability and abrasion performance.
