Abstract

In this study, monolithic carbon coatings were successfully produced onto iron substrates by conventional plasma spraying using fullerene granules. The monolithic carbon coatings obtained here are continuous and dense, and the interfaces with the iron substrate have good adhesiveness. The coating speeds estimated from the thickness of the carbon coatings are more than 1 um/min, which are much higher than that of DLC coatings produced by the conventional chemical vapor deposition (CVD) method. The deposited fullerene granules were transformed into nano-crystalline graphite and/or amorphous carbon during the plasma spraying process, and Fe3C was also formed by carburizing. From the obtained results, it is found that plasma spraying is applicable to produce monolithic carbon coatings.
