【Abstract】 Electrodeposited diamond bits on thin-wall steel body are new drilling tools for construction. The key technical problems of the bond strength between the matrix and steel body,the concentricity and diamond segments sealing off from the body are successfully resolved in the studies. Application in construction engineering indicated that the bits have the advantage of high penetration rate,high bonding strength and long drilling life.更多还原
