The invention discloses a fully-constrained weak-sparse
metal powder explosive compaction and
powder plate explosion cladding method. The method comprises the following steps: (1)
processing a
metal plate: forming openings in the side surface of the
metal plate, and cleaning the inner walls of the openings, wherein the shapes and sizes of the openings can be designed and adjusted according to therequirements; (2) filling
metal powder: sealing one opened side of the metal plate, pouring the
metal powder into the openings step by step, compacting the
metal powder to the greatest extent, after all the openings are compactly filled, sealing the other side, wherein the filling density is relevant with the materials of the metal
powder; and (3) putting the metal plate filled with the metal powder on a
cushion plate, putting an explosive on the metal plate, firing the explosive through a
detonator so as to drive the upper part of the metal plate to downwards compact the metal powder to enable the metal powder to be closely combined with the metal plate, so as to finish the cladding between the metal powder and the plate. Compared with traditional explosion cladding techniques, the methodhas the advantages that by fully constraining the metal powder, sparse
waves are weakened, and the compaction of the metal powder and the cladding of the powder plate material can both be realized.
