The invention discloses a preparation method of a high-strength high-toughness bionic-function surface wear resistance composite material, wherein carbon steel is taken as a base material, round pits with different intervals and ratios of pit-depth to pit-diameter or strip-shaped pits with different intervals and ratios of pit-depth to pit-width are processed in the surface of a smooth carbon steel base, original powder of an Al-Ti-C system hard unit is put into the pits and compacted, an in-situ endogenous TiC-Al base metal composited-structure hard unit is prepared through a sintering technique, and so that the high-strength high-hardness high-toughness bionic wear resistance composite material is manufactured. The bionic wear resistance composite material prepared according to the preparation method provided by the invention not only is good in wear resistance, but also is low in production cost, convenient in processing and manufacturing, and wide in scope of application. The effective method is provided to solve the problems of abrasion resistance of a part in the process.
