Description
Technical Field
The invention relates to a composite material, in particular to a preparation method of a strong corrosion-resistant titanium-steel explosion composite material.
Background
The strength of the titanium is high, and the tensile strength of the pure titanium can reach 180kg/mm2 at most. Some steels have higher strength than titanium alloys, but the specific strength (ratio of tensile strength to density) of titanium alloys exceeds that of high-quality steels. The titanium alloy has good heat-resisting strength, low-temperature toughness and fracture toughness, so that the titanium alloy is mainly used as aircraft engine parts and rocket and missile structural parts. Propellant and oxidizer tanks and high pressure vessels. Titanium alloy is also an important corrosion-resistant material for manufacturing chemical equipment, and because of high price, titanium and common metal (steel plate) are often used in a composite manner to meet the requirement. The explosive welding technology is that one material (composite material) is pushed to obliquely collide with another material (base material) at high speed by high-pressure pulse load generated by explosive detonation, the loading stress of the explosive welding technology is far higher than the yield strength of a metal material, the instantaneity (generally measured in milliseconds) of the loading process, the loaded locality of the material, interweaving occurs in a tiny adjacent area of an action point and moves at high speed, and the like, so that metallurgical bonding of the two metals is realized, and a bonding area is in wavy metallurgical bonding. Explosive welding is a high and new technology with practical value for carrying out intermetallic welding and producing metal composite materials by using explosive as energy. The method is characterized in that the metals can be combined instantly, and are welded together simply, quickly and firmly. Compared with welding technologies such as rolling, surfacing, casting and the like, the explosive welding technology has the advantages that: the material has wide adaptability and weldability, and is suitable for most plastic metals or alloys; especially for the welding of large-area metal, the method is the only connection method; the method is suitable for the combination of compatible metals, the combination of non-compatible metals and the metals and alloys which are easy to generate brittle intermetallic compounds; the thermal interface has good thermal conductivity and low interface resistance, the bonding area has no thermal influence area, and the interface is not or only slightly melted by the instant thermal process. However, the explosion welding method can cause the maximum possible bonding between the titanium plate and the substrate, so that a large amount of time is needed for repair welding of the non-bonded part subsequently.
