Sintering of Fine Particles in Suspension Plasma Sprayed Coatings

Suspension plasma spraying is a process that enables the production of finely grained nanometric or submicrometric coatings. The suspensions are formulated with the use of fine powder particles in water or alcohol with some additives. Subsequently, the suspension is injected into plasma jet and the liquid additives evaporate. The remaining fine solids are molten and subsequently agglomerate or ...

Suspension Plasma Sprayed Titanium Oxide and Hydroxyapatite Coatings

The paper aims at development of TiO2, Ca5(PO4)3OH (hydroxyapatite, HA) and their multilayer coatings onto stainless steel, titanium and aluminum substrate using suspension plasma spraying. The total thickness of the coatings was in the range 10 to 150 μm. The suspension on the base of distilled water, ethanol and their mixtures was formulated with the use of fine commercial TiO2 pigment crysta...

Performance 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...

Thermal 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...
