This study aimed to understand the effect of TiO2 content on the thermal shock performance of Al2O3/TiO2 air plasma spray coatings. Three kinds of commercial feedstock powders were used, i.e. Al2O3, Al2O3-13wt%TiO2 and Al2O3-40wt%TiO2. The resulting coatings were studied in terms of micro Vickers hardness test, XRD, SEM and thermal shock test. The last was conducted using a water quenching method. The results showed that both the coating hardness and thermal shock performance decreased with the TiO2 content.

The most common industrial needs of coatings are to improve the surface properties such as, wear resistance, corrosion resistance and thermal conductivity/insulation. The use of expensive high strength materials and super alloys can be mitigated by using low grade materials covered with suitable coatings compatible with the media and service. Air plasma spray deposition method is used to achieve dense coating on substrate. The present research work demonstrates the wear properties of Ni-Cr/Micro-ZrO2 coating prepared through air plasma spray deposition (PSD) method. In this process, ZrO2 particulates of average particle size (10-40µm) were sprayed on Ni-Cr coated AISI 410 grade steel substrate. Distribution of ZrO2 particle was found uniform throughout the coating as revealed from SEM microphotographs. Dry sliding wear tests were performed on Pin-On-Disc Tribometer at room temperature with moderate humidity conditions. Significant improvement in wear performance was observed in Ni-Cr/Micro- ZrO2 coating deposited on steel via PSD which was also evident from worn surface morphology.
