Embodiment 1

[0032] (1) Surface treatment: the substrate super austenitic stainless steel 904L (00Cr20Ni25Mo4.5Cu), the size is 9×2000×5000mm; the transition layer pure titanium plate TA1, the size is 3×2040×5050mm; the composite material 6061 aluminum alloy, The size is 12×2040×5100mm, and the surface of the three to be compounded is polished to remove the surface oxide skin.

[0033] (2) The first explosive welding: first place the transition layer pure titanium plate TA1, the substrate super austenitic stainless steel 904L and the backing plate (ordinary carbon steel, size 15×2000×5000mm) in order from top to bottom Put it on the welding platform, and weld the four corners in contact between the base material and the backing plate to avoid the displacement of the backing plate during the explosive welding process, and the transition layer and the base material are separated by supports with a distance of 8mm. Then brush a layer of butter on the surface of the transition layer and spread...

Abstract

The invention discloses a high corrosion-resistant steel-aluminum composite material for ships and warships and a preparation method thereof. A base plate of the composite material is super austeniticstainless steel, and a composite plate of the composite material is a 6061 aluminum alloy. The preparation method is an explosive welding method. By way of three layers and two times, the preparationmethod comprises the following steps of performing explosive cladding on a transitional layer pure titanium plate and the substrate super austenitic stainless steel first and performing explosive cladding with the composite material 6061 aluminum alloy. The preparation method aims to obtain a steel-aluminum composite material, the cladding rate of which is greater than 99% after explosive weldingtwice by normalizing the dimensions of the composite plate, the transitional layer and the base plate and the dosage of an explosive in explosion twice. Meanwhile, in order to save the explosive andreduce the detonation velocity, quartz sand is added into an emulsion explosive in a ratio of 1: 1. The steel-aluminum composite material prepared by the preparation method disclosed by the inventionhas the characteristics of being high in strength, high in corrosion resistance, light and the like, and has a wide application prospect in military equipment such as ships and warships.

Description

technical field [0001] The invention relates to a steel-aluminum composite material and a preparation method thereof, in particular to a ship-use steel-aluminum composite material with high-strength 6061 aluminum alloy as the composite material and high-corrosion-resistant super austenitic stainless steel as the base material Composite materials and methods for their preparation. Background technique [0002] Ship steel specifically refers to the hull structural engineering steel of sailing ships, mainly plates. Ship steel requires high strength and toughness as well as excellent seawater corrosion resistance. At present, the commonly used ship steels are 16Mn, 15MnTi, etc. Although these steels are cheap, their corrosion resistance is not good, which shortens the service life of ships and endangers the safety of ships. However, the production cost of high-strength and high-corrosion-resistant alloy steel such as HS130 is relatively expensive, and it is difficult to use it...
