The interaction of the SiC–SiCw–B4C–AlN system ceramic composite material (CCM) with the EP648 alloy in the process of high-temperature brazing was studied. The smallest erosion activity both in relation to CCM, and to the EP648 alloy, has HMP solder VPr50. An experimental constructionally similar sample of the nozzle assembly sector was made using uncooled nozzle blade prototypes from CCM. Tests of an experimental constructionally similar sample of the nozzle assembly sector at a temperature of 1500 °C were carried out. No traces of material ablation from the surface of the CMC were found.
