一、概述为了改善钢的抗腐蚀性和抗氧化性,提高其持久强度和疲劳强度;为了用普通的钢材代替昂贵的不锈钢和耐热钢,许多工业发展国家广泛地研究了铁碳合金的渗铬工艺,并在工业生产中推广使用。
I. Overview In order to improve the corrosion resistance of steel and oxidation resistance and improve its long-term strength and fatigue strength; in order to replace the common steel expensive stainless steel and heat-resistant steel, many industrialized countries extensively studied the carbon-carbon infiltration Chromium technology, and promote the use of industrial production.
