“…Most experimental conditions were for coatings at a high-temperature state for non-corrosive media [3]. However, TBCs also gradually fail due to erosion and calcium-magnesium-aluminosilicate (CMAS) attack following long-term exposure to harsh environments [4][5][6]. In reality, the CMAS on the surface of TBCs is usually composed of sand, ash and dust, and melts at temperatures of more than 1200°C.…”

The deterioration of thermal barrier coatings in reaction engines due to Ca-Mg-Al-Si (CMAS) attacks has been an important issue in recent years. Al 2 O 3 -20 wt-% TiO 2 (AT) powder was mechanically doped into yttria-stabilized zirconia (YSZ). The corresponding coatings were fabricated using APS to modify the CMAS corrosion resistance. The corrosion-induced microstructure evolution and the composition development in the YSZ and AT-YSZ coatings were investigated. The AT-YSZ coating contained smaller voids and fewer cracks with a much more obvious laminated structure in contrast with the YSZ coatings. After CMAS attack, the YSZ coating flaked off, while the AT-YSZ coating was strongly bonded to the substrate. Phases from tetragonal (t'-ZrO 2 ) to monoclinic (m-ZrO 2 ) were detected, while the MgAl 2 O 4 spinel and gehlenite Ca 2 Al 2 Si 2 O 8 phases were formed after the CMAS corrosion. AT20 exists independently in the AT-YSZ coating, which readily causes Al 2 O 3 to accumulate in the CMAS and effectively arrests its infiltration.

Plasma Spray Physical Vapour Deposition (PS-PVD) method was designed for production of ceramic layer on nickel superalloys. In typical process before deposition the base material is heated by plasma up to 900 °C. In present article the yttria stabilized zirconia (YSZ) was deposited on low melting point materials: 2017A-type aluminium alloy and Cu-ETP copper. The influence of power current, process time and powder feed rate on structure and thickness of obtained coatings was analysed. During first deposition process the overheating of Al-sample was observed and as result the power current was decreased to 1600 A. In the next experimental the approx. 5 mm thick dense coating was formed. During experimental processes of YSZ deposition on copper the thickness of coating increased from approx. 5 to 22 mm. The copper-oxide layer was formed under ceramic layer. The microscopic assessment showed the difficulties in formation of columnar ceramic layer on use base materials. The obtained coating was characterized by dense structure as a result of lower plasma energy during process. The increasing of power current is not possible in the case of overheating of base material.

“…The Yttria-Stabilized Zirconia (YSZ) coatings are widely used in different applications for increasing of wear or thermal resistance of base materials. In aerospace industry it is used as a thermal insulator in thermal barrier coating (TBC) [1,2,3]. In last year this type of ceramic was applied in biomedical applications such as dental implants [4].…”

The plasma spraying is commonly used in medical application. The Atmospheric Plasma Spray (APS) method was applied for production of yttria-stabilized zirconia (YSZ) on AISI 316L stainless steel surface and also on Ti6Al4V titanium alloy surface. In present article two examples of coatings production were presented. In first experimental the YSZ was plasma sprayed (APS) on 316L stainless steel surface. The coating was deposited using A60 (Thermico) plasma torch. The initial parameters were selected and it was concluded that minimal power current was 500A. The thickness of obtained coating was in range 100-150 micrometers. The X-ray phase analysis showed the presence of tetragonal t-phase of ZrO2. The lamellar structure of coatings with large porosity was observed. In second experimental the newly developed Plasma Spray Physical Vapor Deposition method (PS-PVD) was used. The YSZ coating was deposited on titanium Grade 5 surface. The conducted research showed the formation of two types of coatings structure. When the power current was lower (2000 A) the dense lamellar-like coatings was obtained. If the power current was increased (up to 2200A) the columnar ceramic coating was observed.
