Embodiment Construction

[0007] best practice

[0008] A honeycomb steel plate with a hole diameter of 8 mm, a hole depth of 2 mm, and a wall thickness of 0.5 mm is used as the die of the extrusion die. Prepare C powder and Ti powder with a particle size of 200 mesh at an atomic ratio of 1:1, then add Ni powder with a total weight of 10-20%wt of C powder and Ti powder, mix well to make a mixture, and use it to match the die The mold steel punch presses the mixture into the honeycomb holes of the honeycomb steel plate to form a prefabricated block. Put a 10mm thick steel plate at the bottom of the closed mold, arrange 5mm thick mixed powder of Ni powder and Ti powder on the surface of the steel plate, the mixing ratio of the two is 1:1 (atomic ratio), and place the honeycomb steel plate with the prefabricated block On the top of the mixed powder of Ni powder and Ti powder, and then put quartz sand on it, vacuum or inert gas protection 200 ℃ ± 10 ℃ after preheating, use laser beam to ignite the prefabr...

Abstract

The invention relates to a reaction hot pressing method for manufacturing a honeycomb ceramic interlayer composite plate on the surface of a steel plate. The method includes the following process: utilizing a honeycomb steel plate as a recessed die of an extrusion die, mixing carbon powder and titanium powder according to chemical quantity, adding nickel powder occupying 10-20%wt of the total quantity of the carbon powder and the titanium powder, evenly mixing to obtain a mixed material, pressing the mixed material into honeycomb holes through a terrace die matched with the recessed die to obtain pre-manufacture blocks, placing the steel plate at the bottom of a closed die, placing the mixed powder of the nickel powder and the titanium powder on the surface of the steel plate, placing the honeycomb steel plate with the pre-manufacture blocks on the mixed powder, then placing quartz sand on the honeycomb steel plate, ignite the pre-manufacture blocks and the mixed powder in the honeycomb holes through high-energy flame to enable the blocks and the powder to conduct self-propagating reaction, pressing the quartz sand through the terrace die to obtain a metal ceramic honeycomb coating plate and surfacing a metal surfacing layer on the surface of the metal ceramic honeycomb coating plate in pressurization mode by the plasma surfacing process to obtain the honeycomb ceramic interlayer composite plate. The honeycomb coating, a base body and surface metal are bonded in metallurgical mode and high in bonding strength.

Description

technical field [0001] The invention relates to a method for preparing a honeycomb ceramic sandwich composite plate on the surface of a steel plate. It belongs to the technical field of surface engineering. Background technique [0002] The honeycomb ceramic sandwich steel plate has good impact resistance. The honeycomb ceramic sandwich steel plate prepared on the surface of the steel plate by the existing technology is mostly bonded by adhesive bonding, which has low bonding strength, poor high temperature performance and low service life. Contents of the invention [0003] The object of the present invention is to overcome the above disadvantages and provide a reaction hot pressing method for preparing honeycomb ceramic sandwich composite panels on the surface of steel plates with high bonding strength, good high temperature performance and long service life. [0004] The object of the present invention is achieved like this: a kind of steel plate surface prepares the r...
