Beschreibung
Zusammenfassung:	The invention discloses an auger bit with abrasion resistance and toughness. The auger bit includes an abrasion-resistant head, a bit body and a bit handle from top to bottom in sequence. The bit bodyand the bit handle are formed integratedly. The lower end of the abrasion-resistant head is inlaid in an abrasion-resistant head groove of the top end of the bit body. An alloy reinforcing micro-region is arranged on the surface of the bit body. The alloy reinforcing micro-region is formed by a micro-molten pool wrapping enhanced phase particles in the micro-molten pool in the subsequent rapid cooling and solidifying process, wherein the micro-molten pool is formed by laser melting a bit body base material. A preparing method comprises the steps that (1) raw material forging, (2) bit body vehicle outer round step, (3) abrasion-resistant head groove drilling at the top end of the bit body, (4) abrasion-resistant head brazing, (5) heat treatment, (6) shot blasting, (7) spring clamping, (8)rust removing treatment, a
