Manufacturing nanostructured YSZ coatings by suspension plasma spraying (SPS): effect of injection parameters
The suspension plasma spraying process is investigated by using shadow imaging techniques to appreciate the different trajectories of the liquid jet interacting with a DC highenergy plasma flow. Then, the modelling of different liquid injections (isolated droplet, train of droplets and continuous jet) helps to determine which injection type must be preferred. From that, coating depositions have...
متن کاملPerformance Testing of Suspension Plasma Sprayed Thermal Barrier Coatings Produced with Varied Suspension Parameters
Suspension plasma spraying has become an emerging technology for the production of thermal barrier coatings for the gas turbine industry. Presently, though commercial systems for coating production are available, coatings remain in the development stage. Suitable suspension parameters for coating production remain an outstanding question and the influence of suspension properties on the final c...
متن کاملEffect of TiO2 addition on the microstructure and nanomechanical properties of Al2O3 Suspension Plasma Sprayed coatings
Alumina-titania coatings are widely used in industry for wear, abrasion or corrosion protection components. Such layers are commonly deposited by atmospheric plasma spraying (APS) using powder as feedstock. In this study, both Al2O3 and Al2O3-13 wt% TiO2 coatings were deposited on austenitic stainless steel coupons by suspension plasma spraying (SPS). Two commercial suspensions of nanosized Al2...
متن کاملNano Crystalline Ceramic and Ceramic Coatings Made by Conventional and Solution Plasma Spray
Nanostructured ceramic coatings produced by plasma spray processes are being developed for a wide variety of applications that require resistance to wear, erosion, cracking and spallation [1]. In addition the process is being developed to make near net shaped ceramic performs by dissolution of the substrate after spraying. Attractive properties associated with a nanostructure (in general referr...
متن کاملThermal Conductivity Analysis and Lifetime Testing of Suspension Plasma-Sprayed Thermal Barrier Coatings
Suspension plasma spraying (SPS) has become an interesting method for the production of thermal barrier coatings for gas turbine components. The development of the SPS process has led to structures with segmented vertical cracks or column-like structures that can imitate strain-tolerant air plasma spraying (APS) or electron beam physical vapor deposition (EB-PVD) coatings. Additionally, SPS coa...
