Brazed Joint

Presents the results of studies on the microstructure an opposite combination of nickel heat-resistant alloys of a brazed joint. The chemical composition of the phases formed as a result of the interaction of the mono-crystal alloy VKNA-25, heat-resistant alloy EP975 and complex alloyed solder VPr56 was investigated. The main regularities of the microstructure of the brazed joint changes during heat treatment were established. The dependence is established and the formula is derived for obtaining the optimal microstructure of the brazed seam with different duration of heat treatment and the size of the assembly gap.

Microhardness distributions, surface morphology, and elemental composition of a deposited layer of a heat-resistant alloy of the type P2M8U steel formed by plasma surfacing in a protective-alloying nitrogen medium are studied. It was established that the surfacing technology and surfacing material allows to obtain a high-quality deposited alloy without cracks, pores, slag inclusions and defects of macro- and microstructure. It has been established that the deposited material is pearlite grains at the boundaries and grain junctions of which are carbonitrides based on iron, tungsten, chromium, molybdenum, aluminum (Fe6 W6 NC and AlN).
