Beschreibung
Zusammenfassung:	A refractory metal core laminate assembly, comprising: a first refractory metal core (64) having exterior surfaces (66) and a first side (68) and a second side (70) opposite the first side (68); a second refractory metal core (72) having exterior surfaces (74) and a first side (76) and a second side (78) opposite the first side (76), the second refractory metal core (72) being arranged above the first refractory metal core (64) with the second refractory metal core first side (76) facing the first refractory metal core second side (70); a layer (82) of a powder bed material (80) between the first refractory metal core second side (70) and the second refractory metal core first side (76); and a coating (92) of the powder bed material (80) coupled to the first refractory metal core exterior surfaces (66) and the second refractory metal core exterior surfaces (74).
