Zusammenfassung:	According to the present invention, a method for evaluating a nickel-chromium-aluminum based coating comprises: a pretreatment step of polishing a coating; a copy step of copying a surface corrugated shape of the polished coating to a copy base material; an analysis step of analyzing the number of alpha-chromium (-Cr) for each unit area in the copy base material; and a calculation step of calculating remaining durability, hardness, or a thermoregulatory coefficient of the coating from the number of the alpha-chromium (-Cr). 본 발명의 니켈-크롬-알루미늄계 코팅의 평가방법은 코팅을 연마하는 전처리단계; 상기 연마된 코팅의 표면 요철형상을 복제기재에 복제하는 복제단계; 상기 복제기재에서 단위면적당 알파-크롬(α-Cr)의 개수를 분석하는 분석단계; 및 상기 알파-크롬(α-Cr)의 개수로부터 코팅의 잔여수명, 경도 또는 열화도 계수를 산출하는 단계; 를 포함한다.
