Slurry erosion performance of detonation gun (D-gun) spray ceramic coatings (Al 2 O 3 and Al 2 O 3 -13TiO 2 ) on CF8M steel has been investigated. Slurry collected from an actual hydro power plant was used as the abrasive media in a high speed erosion test rig. Attempt has been made to study the effect of concentration (ppm), average particle size and rotational speed on the slurry erosion behaviour of these ceramic-coated steels under different experimental conditions. The analysis of eroded samples was done using SEM, XRD and stylus profilometry. The slurry erosion performance of the D-gun spray Al 2 O 3 -13TiO 2 -coated steel has been found to be superior to that of Al 2 O 3 -coated steel. Both the coatings showed brittle fracture mechanism of material removal during the slurry erosion exposure.

“…Plasma sprayed Al 2 O 3 based coatings are mostly utilized for distinct industrial applications owing to their better properties like low production cost, excellent wear, abrasion and erosion resistance. Sundararajan et al [11] observed that thermal sprayed Al 2 O 3 and Al 2 O 3 -TiO 2 coating can be utilized to resist wear. However, the coatings deposited by HVOF processes have indicated good tribological performance [12].…”

The current work evaluates the effect of hot corrosion on ASTM-SA213-T-22 Steel with a coating of 100Al 2 O 3 and 20TiO 2 -Al 2 O 3 at 900°C in the molten salt environment of (Na 2 SO 4 -60% V 2 O 5 ). The coatings were sprayed by plasma spray technique. The bare and coated samples were placed inside the muffle furnace at 900°C for 50 cycles. Each cycle consisted of heating for 1 h and 20 min of cooling at ambient temperature. The kinetics of hot corrosion was analyzed by measuring mass gain after each cycle. The results were achieved by using visual examination, mass change measurement, XRD and SEM/EDS analysis. The result revealed that bare steel was more affected with corrosion and gained more mass due to the development of iron oxide (Fe 2 O 3 ) than the coated sample. Fe 2 O 3 and Cr 2 O 3 were found as major phase in oxide scale of T-22 uncoated steel specimen. The 100Al 2 O 3 and 20TiO 2 -Al 2 O 3 coated specimen indicated the reduction in mass gain by 25.41% and 67.02% respectively as compared to uncoated specimen. Al 2 O 3 coating with the combination of TiO 2 showed better adhesion properties. The presence of TiO 2 enhanced the durability and strength of Al 2 O 3 coating to withstand high temperatures.

“…D-Gun sprayed coatings are more wear resistant than bare or uncoated material which is in agreement with what was observed by Murthy et al [22], Sundararajan et al [23], and Wang et al [24]. The wear rate is observed to increase with increase in applied load which is in agreement with what was observed by Qureshi and Sheikh [25].…”

Thermal spray coatings can be applied economically on machine parts to enhance their requisite surface properties like wear, corrosion, erosion resistance, and so forth. Detonation gun (D-Gun) thermal spray coatings can be applied on the surface of carbon steels to improve their wear resistance. In the present study, alloy powder cermet coatings WC-12% Co and Cr3C2-25% NiCr have been deposited on ASTM A36 steel with D-Gun thermal spray technique. Sliding wear behavior of uncoated ASTM A36 steel and D-Gun sprayed WC-12% Co and Cr3C2-25% NiCr coatings on base material is observed on a Pin-On-Disc Wear Tester. Sliding wear performance of WC-12% Co coating is found to be better than the Cr3C2-25% NiCr coating. Wear performance of both these cermet coatings is found to be better than uncoated ASTM A36 steel. Thermally sprayed WC-12% Co and Cr3C2-25% NiCr cermet coatings using D-Gun thermal spray technique is found to be very useful in improving the sliding wear resistance of ASTM A36 steel.
