Beschreibung
Zusammenfassung:	A raw powder having a composition containing, in weight percent, B: 2.2 to 3.0%; Si: 3.0 to 5.0%; Mo: 18 to 25%; Cu: 1 to 15%, the balance of Ni and unavoidable impurities, with a weight ratio of Mo content to B content being from 7 to 9, is produced using a molten metal spraying method, and the raw powder is then sintered, thereby a corrosion-resistant and wear-resistant Ni-based alloy is produced.
