Abstract

By applying an aluminum coating to the copper-nickel alloy resistor, we successfully utilized air sintering. At 800 and 850°C, the alloy was sintered within an aluminum layer. This coating of aluminum serves as a protective layer. The copper-nickel was not oxidized as a result. After wet etching, the protective coating of aluminum was removed, leaving alloy resistors with Temperature Coefficient of Resistance (TCR) values of 417.86 ppm/°C. We produced an alloy paste using copper-nickel alloy (7:3) and then used screen printing to create thick-film alloy resistors. Therefore, it is feasible to create copper-nickel alloy resistors by air sintering.

空气烧结铜镍合金电阻器，铝层可防止氧化

通过在铜镍合金电阻器上涂一层铝涂层，我们成功地利用了空气烧结技术。在 800 和 850°C 的温度下，合金在铝层中烧结。这层铝涂层起到了保护层的作用。铜镍合金没有因此而氧化。湿法蚀刻后，去掉铝保护层，合金电阻器的电阻温度系数 (TCR) 值为 417.86 ppm/°C。我们使用铜镍合金（7:3）制作了合金浆料，然后使用丝网印刷技术制作了厚膜合金电阻器。因此，用空气烧结法制造铜镍合金电阻器是可行的。
