A memory alloy spring, a method for manufacturing the same, and a spring valve

Abstract

The application relates to the functional material technical field, and provides a memory alloy spring, a preparation method thereof and a spring valve. The memory alloy spring comprises a spring base body and a deposition layer wrapped on the outer surface of the spring base body, and the deposition layer comprises manganese-containing deposits. The memory alloy spring provided by the application contains manganese elements in the deposition layer, the manganese elements can significantly improve the resistivity of the spring base body, after the resistivity is improved, the joule heat generation efficiency of the spring base body is significantly improved under the condition of the same loading voltage, so that the heating performance of the spring base body is obviously optimized, and the response speed is improved. Meanwhile, the deposition layer can be used as a protective layer to isolate the erosion of the external environment on the spring base body, the salt mist resistance of the memory alloy spring is improved, and the memory alloy spring has higher service life and reliability.
