Zusammenfassung:	The invention provides a part resistant to erosion wear and a manufacturing method for same. 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). 本发明提供种耐砂土磨损配件及其制造方法。耐砂土磨损配件即斗齿(20)具有：基部(25)、覆盖基部(25)的表面的部分即前端面(25A)而与基部(25)接触来配置的第堆焊层(271)、以及在第堆焊层(271)上配置的第二堆焊层(272)。第堆焊层(271)及第二堆焊层(272)各自包括：由铁或钢形成的母相(95)、以及在母相(95)中分散且由金属陶瓷形成的金属陶瓷粒(91)。
