Abstract
The invention discloses a preparation method of a brine-corrosion resistant alloy. The brine-corrosion resistant alloy is obtained by melting, and during smelting the following elements are added in percentage by weight: 4-8% of Ni, 0.5-0.9% of C, 1-2% of Pb, 0.3-0.6% of Cr and the balance of Cu. The alloy prepared by adopting the preparation method disclosed by the invention has good strength and toughness, and the galvanic corrosion effect between the alloy and the copper-nickel alloy can be reduced significantly.
Description
Technical field
The invention belongs to field of alloy material, be specifically related to a kind of preparation method of salt water resistance resistant alloy.
Background technology
In sea water system, nickelaluminium bronze is widely used because of good corrosion resistance nature, but when the defect of nickelaluminium bronze is to support the use with Alpaka, because both corrosion potentials differ greatly, galvanic effect clearly.
Summary of the invention
The technical problem to be solved in the present invention overcomes existing defect, provide a kind of can with the preparation method of the matching used salt water resistance resistant alloy of Alpaka.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
A preparation method for salt water resistance resistant alloy, described alloy is obtained by melting, the alloying element added during melting and percentage composition as follows: Ni 4-8, C 0.5-0.9, Pb 1-2, Cr 0.3-0.6, surplus is copper.
The alloy of gained of the present invention has good intensity and toughness, obviously can reduce the galvanic effect of itself and Alpaka.
