Description

1one

Изобретение относитс  к неразрушающим методам контрол  и может быть использовано дл  изготовлени  демпферов ультразвуковых пьезоэлектрических преобразователей.The invention relates to non-destructive testing methods and can be used to manufacture ultrasonic piezoelectric transducer dampers.

Известны сплавы Вуда и Розе, примен емые в качестве особо легкоплавких припоев L J.Wood and Rose alloys are known that are used as very low-melting solders L J.

Указанные сплавы обладают высоким затуханием ультразвука и характеристическим акустическим импедансом , близким к импедансу пьезокерамики .These alloys have a high attenuation of ultrasound and a characteristic acoustic impedance close to the impedance of piezoceramics.

«"

Предлагаетс  применение сплавов Вуда или Розе в качестве материала демпферов пьезопреобразователей ультразвуковых дефектоскопов и толщино- jo мерев.It is proposed to use Wood or Rose alloys as a material for the dampers of piezoelectric transducers of ultrasonic flaw detectors and thicknesses.

В таблице приведены характеристики сплавов Вуда и Розе.The table shows the characteristics of alloys Wood and Rose.

toto

Сплавы Вуда и Розе имеют температуру плавлени  значительно ниже точки Кюри большинства пьезоматериалов , что не требует дополнительной пол ризации пьезопреобразователей после изготовлени  демпферов.Wood and Rose alloys have a melting point well below the Curie point of most piezomaterials, which does not require additional polarization of piezo transducers after the manufacture of dampers.
