超聲波探傷換能器性能及其測試、評價
超(chao)(chao)(chao)(chao)聲(sheng)(sheng)(sheng)探傷儀、超(chao)(chao)(chao)(chao)聲(sheng)(sheng)(sheng)波(bo)(bo)探頭(tou)、測試塊(kuai)和(he)耦合劑等是超(chao)(chao)(chao)(chao)聲(sheng)(sheng)(sheng)檢(jian)測系統的重要(yao)組成部分。超(chao)(chao)(chao)(chao)聲(sheng)(sheng)(sheng)波(bo)(bo)檢(jian)測的主要(yao)設(she)備是超(chao)(chao)(chao)(chao)聲(sheng)(sheng)(sheng)波(bo)(bo)探傷儀,它可(ke)以快速、方便、無(wu)損傷地檢(jian)測、定位、評(ping)估和(he)診斷工件中的各種(zhong)缺(que)陷。由于超(chao)(chao)(chao)(chao)聲(sheng)(sheng)(sheng)波(bo)(bo)探頭(tou)可(ke)實現電聲(sheng)(sheng)(sheng)轉換(huan)(huan),所(suo)以超(chao)(chao)(chao)(chao)聲(sheng)(sheng)(sheng)波(bo)(bo)探頭(tou)也叫超(chao)(chao)(chao)(chao)聲(sheng)(sheng)(sheng)波(bo)(bo)換(huan)(huan)能(neng)器,其電聲(sheng)(sheng)(sheng)轉換(huan)(huan)是可(ke)逆的,且轉換(huan)(huan)時間極...
