“…The Taguchi approach is normally suitable for the optimization of a single objective. To solve the multi-objective optimization of thermal spray processes, several authors have developed the Taguchi-OEC technique, 9 Taguchi-based gray relational analysis 10,11 and response surface methodology. 12,13 Pal and Gauri 14 introduced the multiple regression-based weighted signal-to-noise ratio (MRWSN) optimization method, which was based on a combination of the Taguchi and mathematical regression techniques.…”

In this study, the optimal process parameters for a high-velocity oxygen fuel spray, which was used to deposit WC-12Co coating on a 16Mn steel substrate, were studied to simultaneously improve the microhardness, adhesion strength, and porosity of the coating. To this end, trial tests were conducted to determine the feasible ranges of the spray parameters: powder feed rate ( A), spray distance ( B), and oxygen/propane mixture ratio ( C). Taguchi orthogonal array (L9) experimental design was used to determine regression formulae for the microhardness, adhesion strength, and porosity. Then, based on a method using the multiple regression-based weighted signal-to-noise ratio, the optimal spray parameters were identified. To verify the optimization results, confirmation experiments were carried out. An analysis of variance was also conducted to check the proportion of contribution of the spray parameters on the output quality characteristics. The confirmation test results proved that the predicted and measured results were in good agreement. The optimal conditions of the high-velocity oxygen fuel spray were: A = 32 g/min, B = 0.35 m, and C = 5. The estimated optimal coating properties were: microhardness = 1335.784 HV, adhesion strength = 64.659 MPa, and porosity = 1.797%. The oxygen/propane ratio showed the highest contribution to the microhardness, whereas the most influential factor for both adhesion strength and porosity was the spraying distance.

“…A decrease in spraying particle size increases the corrosion resistance of coating materials [8]. The best quality of spray can be obtained by optimising HVOF parameters such as particle velocity, powder feed rate, and spray distance, and in the response optimisation, the spray distance is indicated as the most significant factor affecting the spray/coating quality [9]. It was reported that pit corrosion occurred at the boundary of a crystalline Fe alloy solid [10].…”

The high-velocity oxyfuel spraying (HVOF) method was used to coat Fe-Cr-Ti-based coating material Fe60Mo5C15Si10Cr0Ti10, Fe50Mo5C15Si10Cr10Ti10, Fe50Mo5C15Si10Cr10Ti0 on base material 316L stainless steel. A comparative analysis was performed to investigate the effect of alloying element chromium and titanium on corrosion and erosion properties of Fe-Cr-Ti coating material. NaCl solution (3.5 wt.) was used for the study of corrosion behaviour. The steady-state erosion wear was examined by varying parameters such as impact speed and impact angle. It was found that the micro-hardness and fracture toughness of Fe-Cr-Ti coating material with 10 wt-% titanium were 18.02 and 5.08% more than those of the coating material with 10 wt-% chromium, respectively. This showed that titanium played a more significant role than chromium in terms of mechanical and erosion properties and a less significant role in terms of corrosion behaviour. Fe50Mo5C15Si10Cr10Ti10 indicated the least wear and a smooth surface with very few pores and wear scars.
