超聲波探傷換能器性能及其測試、評價
超(chao)聲(sheng)(sheng)(sheng)(sheng)探(tan)傷儀、超(chao)聲(sheng)(sheng)(sheng)(sheng)波(bo)(bo)探(tan)頭、測試塊和(he)耦合劑等是超(chao)聲(sheng)(sheng)(sheng)(sheng)檢測系(xi)統的重(zhong)要(yao)組成部分(fen)。超(chao)聲(sheng)(sheng)(sheng)(sheng)波(bo)(bo)檢測的主要(yao)設備是超(chao)聲(sheng)(sheng)(sheng)(sheng)波(bo)(bo)探(tan)傷儀,它可以(yi)(yi)快速、方(fang)便、無損(sun)傷地檢測、定(ding)位(wei)、評估和(he)診斷工件(jian)中的各種缺陷。由于超(chao)聲(sheng)(sheng)(sheng)(sheng)波(bo)(bo)探(tan)頭可實現(xian)電聲(sheng)(sheng)(sheng)(sheng)轉(zhuan)換(huan)(huan),所以(yi)(yi)超(chao)聲(sheng)(sheng)(sheng)(sheng)波(bo)(bo)探(tan)頭也(ye)叫超(chao)聲(sheng)(sheng)(sheng)(sheng)波(bo)(bo)換(huan)(huan)能器,其電聲(sheng)(sheng)(sheng)(sheng)轉(zhuan)換(huan)(huan)是可逆的,且(qie)轉(zhuan)換(huan)(huan)時間極...
