Abstract

Zirconia is a ceramic material that is relatively cheap and easy to purify from mineral form. Zirconia powder has stable properties under high temperature conditions making it suitable for use as a coating for steel substrates. Ceramic composite coating is one option that can be used to increase its durability by adding filler which has lubricant properties. In this research, hBN, MoS2 and graphite were used as filler coatings. The coating method used is slurry spray, which is a simple method and there is a subsequent sintering process so that the resistance of the coating to the substrate is better. The effect of the coating is seen before and after the sintering process on the surface and thickness. And to see the adhesion of the coating to the substrate, a thermal shock test was carried out. From the test results, it was found that sintering had a significant effect on the coating surface, where the defects on the coating surface became fewer and more even. The optimum temperature for sintering is 600oC where the least porosity is obtained.
