Beschreibung
Zusammenfassung:	A tooth (20) that is a part resistant to erosion wear comprises a base (25), a first built-up layer (271) that is disposed in contact with the base (25) so as to cover a distal end face (25A) that is a part of the surface of the base (25), and a second built-up layer (272) that is disposed on the first built-up layer (271). The first built-up layer (271) and the second built-up layer (272) each comprise a parent phase (95) made from steel or iron, and cermet particles (91) that consist of cermet and that are dispersed in the parent phase (95).
