Cold spray deposition of Inconel 718 in comparison with atmospheric plasma spray deposition

Applied Surface Science, 2021
Abstract Inconel 718 is a Ni-based superalloy which has been widely used in aerospace industry. Repairing of Inconel 718 components has been usually carried out using atmospheric plasma spray (APS) and high velocity oxy fuel (HVOF) spray techniques.

Ablation properties of HfB2 coatings prepared by supersonic atmospheric plasma spraying for SiC-coated carbon/carbon composites

Surface & Coatings Technology, 2019
In order to improve the ablation resistance of carbon/carbon (C/C) composites, hafnium boride (HfB 2 ) coatings were prepared on the surface of SiC-coated C/C composites by supersonic atmospheric plasma spraying (SAPS).

Mechanical properties and thermal cycling behavior of Ta2O5 doped La2Ce2O7 thermal barrier coatings prepared by atmospheric plasma spraying

Journal of Alloys and Compounds, 2019
La2Ce2O7 (LC) is drawing increasing attention to be a new candidate material for thermal barrier coatings (TBCs) because of its higher phase stability, lower thermal conductivity and larger thermal expansion coefficient (TEC) than the traditional yttria ...

Atmospheric Plasma-Sprayed Hydroxyapatite Coatings with (002) Texture

Journal of Thermal Spray Technology, 2018
Hydroxyapatite (HA) coatings are being widely used in biomedical applications owing to their excellent biocompatibility and osteoconductivity. Recent studies have demonstrated that the crystallographic texture plays an important role in improving the chemical stability and mechanical properties of HA coatings. In this study, optimized APS parameter was

Modelling of plasma spraying of ceramic coatings at atmospheric pressure

Ceramics International, 1991
Abstract Many works have been devoted to the study of plasma sprayed coatings and, if progresses have been made, the coatings are still resulting more from an empirical understanding than from a scientific one. In this paper are presented what is the present state of our knowledge in the modelling and measurement of the parameters controlling the ...

Present status of low pressure and atmospheric plasma spraying

Vacuum, 1990
Abstract New developments in the fields of spray gun engineering, powder engineering, process control and plasma technology are seen to stimulate each other. As a result, plasma spraying extends its application field. We report recent achievements in spray equipment, powders and plasma models: strongly vortex-stabilized guns, guns with adjustable arc

Thermal and mechanical properties of Ta2O5 doped La2Ce2O7 thermal barrier coatings prepared by atmospheric plasma spraying

Journal of the European Ceramic Society, 2019
La2Ce2O7 (LC) is a new promising thermal barrier coating (TBC) material for high-temperature applications. However, the sudden decrease of thermal expansion coefficient (TEC) at ∼623 K limits its application. In this study, the plasma-sprayed La2Ce1.7Ta0.

Graded coating of hydroxyapatite and titanium by atmospheric plasma spraying

Materials Letters, 1999
Abstract Graded coating of hydroxyapatite and titanium by plasma spraying was attempted as an alternative means to direct deposition of hydroxiapatite on titanium. The application of multiple layers of hydroxyapatite and titanium mixtures ensured a gradual change in composition across the interface.

Microstructure and self-healing properties of multi-layered NiCoCrAlY/TAZ/YSZ thermal barrier coatings fabricated by atmospheric plasma spraying

Applications of Surface Science, 2019
In this paper, the multi-layered self-healing thermal barrier coatings (TBCs) have been fabricated by atmospheric plasma spraying (APS). The phase composition of the sprayed feedstock and the as-sprayed coating have been characterized.
