Embodiment 1

[0015] A method for preparing a nickel-silver alloy material. The metal silver sheet with a thickness of 0.3mm is stacked in a completely overlapping manner on top of a nickel foam material with a surface density of 320g / ㎡ and a thickness of 1.0mm, and then the thickness is 0.4m / min. The feed rate enters the heat treatment furnace filled with hydrogen for heat treatment. The volume of hydrogen accounts for 60% of the inner cavity volume of the heat treatment furnace. The entrance and exit of the heat treatment furnace are both 0.2m 3 The flow rate of / min is continuously filled with nitrogen gas. The heat treatment furnace is divided into the first temperature zone, the second temperature zone and the third temperature zone in turn from the inlet to the outlet. The temperature in the first temperature zone is controlled at 700 ° C. In the first temperature zone The heat treatment time is controlled to be 3min, the temperature in the second temperature zone is controlled to be 8...

Abstract

The invention provides a method for preparing a nickel-silver alloy material. Metal silver sheets are stacked on top of the nickel foam material in a completely overlapping manner, and then entered into a heat treatment furnace filled with hydrogen at a certain feed rate for heat treatment. The heat treatment furnace is divided into the first temperature zone, the second temperature zone and the third temperature zone in turn from the entrance to the exit. The temperature in the first temperature zone is controlled at 650-750°C, and the heat treatment time in the first temperature zone is controlled at 2-5 minutes. , the temperature in the second temperature zone is controlled at 750-850°C, the heat treatment time in the second temperature zone is controlled at 5-8min, the temperature in the third temperature zone is controlled at 960-1050°C, and the heat treatment time in the third temperature zone is controlled at 10min Above, the nickel-silver alloy material is obtained after cooling. The method of the invention has simple process and less pollution, and the nickel-silver alloy material prepared by it has lower resistance and higher elongation.

Description

technical field [0001] The invention relates to a preparation method of a nickel-silver alloy material. Background technique [0002] In modern civilization, cars have become an indispensable means of transportation for human beings. However, with the rapid development of the automobile industry and the continuous increase in automobile production and ownership, automobiles also bring air pollution, that is, automobile exhaust pollution. Gasoline will release a variety of harmful substances during combustion, such as nitrogen oxides, carbon monoxide, hydrocarbons and other pollutants. Among them, nitrogen oxides are more poisonous than carbon monoxide. They damage human eyes and lungs and form photochemical smog. , is the main substance that produces acid rain, which can turn plants from green to brown until they die on a large scale. The most direct consequence is global warming; It may induce angina pectoris, coronary heart disease and other diseases; hydrocarbons will f...
