The invention provides an anti-wear bucket tooth for an excavator and a production process thereof, and relates to the technical field of bucket tooth production. The anti-wear bucket tooth comprisesthe following components in percentage by mass: 1.0-2.0 wt % of C, 12.0-20.0 wt % of Cr, 1.0-2.0 wt % of Ni, 0.5-1.5 wt % of Mn, 0.8-1.2 wt % of Si, 0.3-0.4 wt % of Ti, 0.2-1.0 wt % of Zr, 0.1-0.2 wt% of Re, 0.05-0.1 wt % of B, 0.2-0.3 wt % of Y, 0.1-0.3 wt % of W, 0.05-0.1 wt % of Nb, 0.06-0.10 wt % of P, 0.02-0.06 wt % of S, 2.0-3.0 wt % of a coupling agent, 1.6-2.0 wt % of a defoaming agent, 2.2-2.6 wt % of a flexibilizer and the balance of Fe and impurities. According to the invention, a plurality of wear-resistant components are adopted as bucket tooth fillers, and are reasonably proportioned, so that the components cooperate with each other, and the mechanical property of the bucket tooth is remarkably improved, and meanwhile, the prepared bucket tooth prepared through additive addition, heat treatment and the like is high in toughness, high in hardness, high in tensile strength, high in wear resistance and corrosion resistance, and is convenient to use and excellent in performance.
