摘要：

The hybrid-technological combination of the atmospheric plasma spraying for the application of a high-temperature filler metal followed by a brazing process was analyzed in terms of structure and mechanical properties of X5CrNi18 10 and NiCr20TiAl brazing joints. The thickness of the filler metal layer was minimized at < 50 mum by optimization of the atmospheric plasma spraying process. The brazing seam is hence partly free from brittle phases and yields a increased ultimate tensile strength of brazed and heat-treated joints at different temperatures (room temperature, 500-degrees-C and 700-degrees-C). Additional information concerning the mechanical properties of the brazing joints was derived from the results of the fractographic examinations of the fracture surfaces and from the characteristic strength values of the long-period creep tests. It was also attempted to apply the results of inductively brazed, cylindrical samples to complex (overlapping joints) and large-surface components produced under practical conditions in the vacuum furnace.
