如果銅的導電性被認為是100%,鈦 3.1%的導電率(lv)。 鈦(tai)(tai)合(he)金(jin)(jin)材(cai)(cai)(cai)料的(de)導(dao)電(dian)(dian)(dian)(dian)性能相對較差,電(dian)(dian)(dian)(dian)阻(zu)率(lv)約(yue)(yue)(yue)為(wei)1.5-2.5μΩ·cm,比同等(deng)條件下(xia)的(de)銅(電(dian)(dian)(dian)(dian)阻(zu)率(lv)約(yue)(yue)(yue)為(wei)1.7μΩ·cm)或(huo)鋁(lv)(電(dian)(dian)(dian)(dian)阻(zu)率(lv)約(yue)(yue)(yue)為(wei)2.7μΩ·cm)要高得多。 這(zhe)是(shi)由于(yu)鈦(tai)(tai)合(he)金(jin)(jin)材(cai)(cai)(cai)料本身具有(you)較強的(de)內(nei)阻(zu)和(he)層(ceng)狀結(jie)構導(dao)致的(de)。 鈦(tai)(tai)合(he)金(jin)(jin)材(cai)(cai)(cai)料的(de)不導(dao)電(dian)(dian)(dian)(dian)性主(zhu)要是(shi)由于(yu)其內(nei)部晶粒、晶界、空孔等(deng)缺陷(xian)所引起的(de)。 當(dang)電(dian)(dian)(dian)(dian)流通過鈦(tai)(tai)合(he)金(jin)(jin)材(cai)(cai)(cai)料時(shi),這(zhe)些缺陷(xian)會產生(sheng)散射,影響了電(dian)(dian)(dian)(dian)流的(de)流動(dong)。 此外,鈦(tai)(tai)但是(shi)在(zai)自然界,以及日常生(sheng)活中(zhong)一般(ban)很難見到純鈦(tai)(tai)(TA2/GR2)。
