Method for preparing titanium-coated low-carbon steel composite plate

Abstract

The invention relates to a method for preparing a titanium-coated low-carbon steel composite plate by adopting injection deposition and rolling treatment. According to the method for preparing the titanium-coated low-carbon steel composite plate, first a high-speed injection deposition technology is utilized to deposit 304 stainless steel powder on a pre-treated low-carbon steel plate to serve as a transition layer, pure titanium powder is injected at a high speed and deposited on the transition layer, a titanium-coated low-carbon plate with a compact coating and with an interface in metallurgical bonding is obtained finally through hot rolling, and the titanium-coated low-carbon steel composite plate comprising a low-carbon steel plate layer, a transition metal layer and a pure titanium layer. The singe side or two sides of the surface of the low-carbon steel plate can be coated with titanium conveniently by means of the preparation method, the thickness of a titanium-coated layer can be adjusted flexibly according to actual requirements, the thickness of the prepared titanium-coated layer ranges from dozens of microns to several millimeters, the method is simple in process, the thickness of the titanium-coated layer is controllable, and an interface of the prepared titanium-coated low-carbon steel composite plate is in metallurgical bonding and has the characteristic performance of high bonding strength.

Description

technical field [0001] The invention relates to a preparation method of a titanium-coated low-carbon steel composite plate, in particular to a preparation method of a titanium-coated low-carbon steel composite plate that adopts ultra-high-speed spray deposition and rolling treatment. Background technique [0002] Titanium has many excellent properties, such as low density, high specific strength, good heat resistance, excellent corrosion resistance and biocompatibility, etc., and is widely used in aviation, aerospace, navigation, chemical and other fields. With the development of metallurgical technology, the amount of titanium used in construction, automobile, medical and daily necessities is also growing rapidly. However, due to the low strength and high manufacturing cost of pure titanium, its application is limited. As the most commonly used structural material, carbon steel has some excellent properties, such as mechanical properties, weldability, thermal stability...

AI Technical Summary

Problems solved by technology

However, the common feature of the above methods is to directly use the finished titanium plate to be composited with the steel plate, but due to its own characteristics, the yield of titanium is low, and it is difficult to obtain a titanium-steel composite plate with a thinner titanium clad layer.
