Title: Method of forming screw hole in rigid member
Inventor: MASATOMI HIROAKI
IPC: B23G1/00
Filed: 1987-12-03
Abstract: PURPOSE:To improve reliability on a rigid member in which a screw hole is formed by a method wherein machining of a screw hole is effected such that a hole having size larger than that of the screw hole is formed in the rigid member, and is filled with mixture powder, a pressure powdery material, or preliminary sintered substance, formed by inevitable impurity consisting of a given amount of Cu and a rest on Ni to heat the filler, which is dispersedly bonded as a sintered substance with the inner wall of the hole. CONSTITUTION:A hole having size larger than that of a screw hole is formed in a spot where the screw hole of a rigid member is formed, and the hole is filled with mixture powder, a pressure powder material, or a preliminary sintered substance, having a mixture composition of 5-60wt.% Cu and the rest of Ni and inevitable impurity to heat it. The filler is dispersedly bonded as a sintered substance to the inner wall of the hole, and through application final machining of a screw hole, a screw hole is formed in the rigid member. As a result, a crack is prevented from production in a spot where the screw hole is formed, and a sintered substance can be buried with eminently high bonding strength. This method enables further improvement of reliability on the rigid member in which the screw hole is formed.
