In the present study, powders produced from the volcanic basalt rocks was coated on AISI 1040 steel pre-coated with Ni-5%Al bond-coat by atmospheric plasma spray coating technique. The coated samples were heat-treated at 800C, 900C and 1000C for 1-4 h for crystallization. The phases formed in the basalt base glass ceramic coatings were augite, Fe-diopsite, anorthite and andesine which were detected by x-ray diffraction analysis. The crystallinity degree of the coating layers increased with increase in heat treatment time and temperature. X-ray diffraction intensities of all the phases formed in the coating layer increased with increase in treatment time at 800C and 900C, but increase in the heat treatment time of the heat treatment realized at 1000C resulted to increase of the intensity of augide and diopsite phases while decrease of the intensity of anorthite and andesin phases.
