Explosive cladding structure of aluminum-titanium steel composite board and method for preparing aluminum-titanium steel composite board

The invention discloses an explosive cladding structure of an aluminum-titanium steel composite board and a method for preparing the aluminum-titanium steel composite board. The explosive cladding structure of the aluminum-titanium steel composite board comprises a steel substrate board, a titanium board and an aluminum board; the steel substrate board is placed on the foundation; the titanium board is located above the steel substrate board; the aluminum board is located above the titanium board; a support sheet is used for separating between the steel substrate board and the titanium board, and between the titanium board and the aluminum board; an explosive layer is placed on the upper side of the aluminum board, the explosive layer comprises a main explosive and a high explosive velocity drug bar, and the explosive velocity of the high explosive velocity drug bar is higher than that of the main explosive; the main explosive is uniformly placed on the upper side of the aluminum board; the high explosive velocity drug bar is successively placed in the middle of the upper side of the aluminum board along the direction of the long edge; and the middle part of the explosive layer is connected to a detonator. The explosive cladding structure of the aluminum-titanium steel composite board has the advantages of high adhering rate, high bonding strength, and low cost, and has the characters of the good corrosion resistance and abrasive resistance of the aluminum materials and high strength of the steel board.
