Abstract

As an important problem of construction machinery, it is necessary to study the boundary region of mechanical properties between metal and rock mass to get a rational maintenance of rock excavating tip. Here, the amount of wear and wear length of pure rippertip and hard surfaced one by means of spraying or welding were measured respectively at several different ripping operation sites of land reclamation. It was clarified that the amount of wear of pure tip is fairly correlated to the index of rock mass strength for wear, and the wear resistance and self-sharpness of tip coated by carbide composite welded metal presents to be higher than the other metals. And also, the effect of hardfacing of sprayed metal can not present under high contact pressure, but develops considerably under low pressure.
