Coatings Remelted by Carbon Arc

摘要

Coatings with six kinds of materials of materials and different thickness were prepared by oxy- acetylene flame spraying on carbon steel A3 substrates and then remelted by a new type of carbon arc remelting treatment (CRT) device. The results indicated that all the deposited layers are homog- eneous and compact. The CRT obviously increases the carbon content and the hardness of the de- posited layers.
