Abstract

철계금속 부품의 내마모성과 내식성을 개선하는 방법은 질화 확산기술을 사용하여 미리 처리된 철계금속 부품을 탄산염, 질산염, 수산화물 및 산소화 알칼리 금속염으로 이루어진 용융염욕에 침지하는 것으로 이루어진다. 이것들의 나트륨염으로 환산되고 욕에서 액상인 활성상에 대응하는 탄산염, 질산염 그리고 수산화물의 상대적 음이온 중량비는 11＜CO3 2-＜23, 19＜NO3 -＜37, 6＜Oh-＜19 이고 Cr2O7 2-의 당량으로 환산된 산소화 알칼리 금속염의 중량비는 0.05＜산소화 음이온＜0.5이다.
이 방법은 처리된 부품의 종류에 관계없이 결과의 고도한 재현성을 보증한다.
