用は困難であつた。 Conventionally, methods such as the Telefunken method, active metal method, and hydrogen compound method have been used to metallize ceramics, but all of them are processed at high temperatures.For example, in the Telefunken method, an alloy film is formed on ceramics in advance in a high-temperature furnace. , which then requires high-temperature treatment and complicated operations such as joining with metal by silver brazing, etc., and also requires high-temperature furnaces, vacuum or gas atmosphere, etc., which increases work and cost. However, it was difficult to use it for anything other than items with considerable added value.
本発明は、用途としては、300〜400℃程度以下

An alloy consisting of 0.05 to 40% Cd, with melting points of Zn, Sb,
Depending on the Cd mixing ratio, it can be selected from a wide range of temperatures, from a relatively low temperature of around 330°C to a medium temperature of around 500°C, and has good wettability and excellent workability.

応じて得ることができる。 As described above, the metallizing alloy of the present invention is a Zn-based alloy, which has stronger strength and a higher melting point than a Pb-Sn-based alloy. In other words, by increasing the Sb ratio, it can be used as an alloy for metallization in the medium temperature range, and
If the ratio of Cd is increased, it is possible to create an alloy for metallization in a relatively low temperature range.If these ratios are selected and used appropriately, the alloy for metallization can be made with the required melting point between medium and low temperatures. You can get it depending on.
しかも、三者の比率を選択することにより、ぬ

果を得た。 Next, an example of the present invention will be described. For example, as shown in FIG . And ultrasonic vibration 1KW, 18KHz
is applied to the immersed surface of the alumina, and in the molten state of the metallization 3, it is immediately bonded to the metal substrate 5 as shown in FIG.
In this case, the metal substrate 5 may be preheated to near the melting temperature of the metallized alloy 1, or flux may be used in combination to facilitate bonding, if necessary. The shear fracture strength of the Al 2 O 3 2 and the metal substrate 5 bonded in this way is 4 Kg/mm 2 or more when the immersion time is 60 seconds or more, as shown in the relationship between immersion time and shear strength in Figure 3 . For example, the metal substrate 5 is used as a wear-resistant member for parts that are subject to severe wear, such as hoppers.
When a composite of Al 2 O 3 2 is ultrasonically bonded with the metallizing alloy of the present invention is used, the metallized joint does not peel off during use.
The result was that Al 2 O 3 2 could withstand long-term use until it wore out.

には充分使用できるものである。 As described above, the ceramic metallizing alloy of the present invention is an alloy for metallizing ceramics by ultrasonic vibration at relatively low temperatures, and by changing the alloy ratio, a wide range of required strength and melting point can be selected. This is possible, and it can be used satisfactorily for wear-resistant parts in terms of mechanical strength and heat resistance.
また、超音波により比較的低温でメタライズで
