| description | PROBLEM TO BE SOLVED: To provide a heat-resistant sintering material that has excellent oxidation resistance and is also excellent in both of high temperature wear resistance and salt damage resistance, and a method for producing the heat-resistant sintering material.SOLUTION: A heat-resistant sintering material that is excellent in oxidation resistance, high temperature wear resistance, and salt damage resistance, has a structure in which hard phases are dispersed in a host phase. The total composition has a structure consisting of, in mass%, Cr: 20-38%, Mo: 0.5-3%, Si: 3-7%, C: 0.5-2.5%, with the balance being Fe and unavoidable impurities. The host phase comprises Fe-Cr-Mo-Si, the hard phase comprises Cr-Fe-Mo-C, and the material has a porosity of 2.0% or less.SELECTED DRAWING: Figure 1
【課題】本発明は耐酸化性、耐摩耗性と耐塩害性の両方に優れる耐熱焼結材とその製造方法の提供を課題とする。【解決手段】本発明に係る耐酸化性、高温耐摩耗性、耐塩害性に優れた耐熱焼結材は、母相中に硬質相が分散された組織を有し、全体組成が質量％でＣｒ：２０〜３８％、Ｍｏ：０．５〜３％、Ｓｉ：３〜７％、Ｃ：０．５〜２．５％、残部がＦｅおよび不可避不純物からなる組成を有し、前記母相がＦｅ−Ｃｒ−Ｍｏ−Ｓｉからなり、前記硬質相がＣｒ−Ｆｅ−Ｍｏ−Ｃからなり、気孔率が２．０％以下であることを特徴とする。【選択図】図１ |
