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)(tan)傷儀(yi)、超(chao)聲(sheng)(sheng)(sheng)(sheng)波(bo)探(tan)(tan)頭(tou)、測試塊和耦(ou)合劑等是(shi)超(chao)聲(sheng)(sheng)(sheng)(sheng)檢(jian)測系(xi)統(tong)的(de)重要組(zu)成部分。超(chao)聲(sheng)(sheng)(sheng)(sheng)波(bo)檢(jian)測的(de)主要設備是(shi)超(chao)聲(sheng)(sheng)(sheng)(sheng)波(bo)探(tan)(tan)傷儀(yi),它(ta)可(ke)以(yi)快(kuai)速、方(fang)便、無損(sun)傷地檢(jian)測、定位、評估和診斷工件中的(de)各種缺陷。由于超(chao)聲(sheng)(sheng)(sheng)(sheng)波(bo)探(tan)(tan)頭(tou)可(ke)實現(xian)電聲(sheng)(sheng)(sheng)(sheng)轉換(huan),所以(yi)超(chao)聲(sheng)(sheng)(sheng)(sheng)波(bo)探(tan)(tan)頭(tou)也叫超(chao)聲(sheng)(sheng)(sheng)(sheng)波(bo)換(huan)能(neng)器,其電聲(sheng)(sheng)(sheng)(sheng)轉換(huan)是(shi)可(ke)逆的(de),且轉換(huan)時間極...
