超聲波探傷換能器性能及其測試、評價
超(chao)(chao)聲(sheng)(sheng)探(tan)傷儀、超(chao)(chao)聲(sheng)(sheng)波(bo)(bo)(bo)探(tan)頭、測(ce)試塊和耦合劑等(deng)是(shi)超(chao)(chao)聲(sheng)(sheng)檢測(ce)系統的(de)重要(yao)組成部分。超(chao)(chao)聲(sheng)(sheng)波(bo)(bo)(bo)檢測(ce)的(de)主要(yao)設備是(shi)超(chao)(chao)聲(sheng)(sheng)波(bo)(bo)(bo)探(tan)傷儀,它可(ke)以快速、方便、無損傷地(di)檢測(ce)、定位(wei)、評估和診(zhen)斷工件中(zhong)的(de)各種(zhong)缺(que)陷(xian)。由(you)于超(chao)(chao)聲(sheng)(sheng)波(bo)(bo)(bo)探(tan)頭可(ke)實現電聲(sheng)(sheng)轉換(huan),所(suo)以超(chao)(chao)聲(sheng)(sheng)波(bo)(bo)(bo)探(tan)頭也叫超(chao)(chao)聲(sheng)(sheng)波(bo)(bo)(bo)換(huan)能器,其電聲(sheng)(sheng)轉換(huan)是(shi)可(ke)逆的(de),且轉換(huan)時間極(ji)...
