1 Introduction
Joining ceramic materials with each other and with metals is carried out by two main
methods:
(1) brazing with molten metallic solders [1–3];
(2) solid-phase pressure welding [4–6].
Since ceramic materials, particularly oxide ones, are usually poorly wetted by
molten metals, metal coatings are often used and applied in various ways (electron
beam sputtering, magnetron sputtering, chemical deposition, etc.). Adhesive-active
metals such as titanium, chromium, niobium, and others are most commonly used
to make such coatings. Then, thus metallized ceramic parts are brazed in vacuum or
an inert medium (argon, helium, etc.) by molten metallic solders on the basis of tin,
silver, copper, nickel, etc. In this case, the thickness of the solder seam is from 50 to
100 µm up to several millimeters. Sometimes, multilayer metal coatings are used,
but the thickness of the layers and brazed seams remains high [7–9].
At the same time, there is information that the reduction in the thickness of the
brazed seam leads to a significant increase in the strength of the brazed joint [10–
12]. Obtaining brazed or welded joints of metallized ceramics is possible through
