METHOD FOR TREATING METAL SURFACE BY CHROMIZING AND ION NITRATION

摘要

PURPOSE: A treatment of metal surface is provided by chromizing and ion nitration, which is characterized by good anti-oxidation and abrasion-resistance. CONSTITUTION: The chromizing step(S13) comprises washing step which washes surface of sample more than 10 minutes with acetone after polishing it more than 10um and NH4Cl, Al203 mixture-manufacturing step using Al203 ball. The container with sample and Ti is treated at reduction circumstance of 1000-1300°C about 1-10hours. CrN layer is formed by the ion nitration treatment(S23) after chromizing treatment. The process of ion nitration step comprises sample-washing step, sputtering step(S22), sample-treating step and sample-cooling step(S24).
