The article presents the results of a study on the exploitation properties of flame-sprayed ceramic coatings produced from an oxide ceramic material in the form of powder based on an aluminum oxide (Al2O3) matrix with an addition of 3 % titanium oxide (TiO2) and also on a zirconium oxide (ZrO2) matrix with 30 % of calcium oxide (CaO) on a substrate of unalloyed structural steel of grade S235JR. The buffer layer was produced from a metallic powder on the basis of Ni-Al-Mo. Plates with dimensions of (5 × 200 × 300) mm and also the front surfaces of f40 × 50 mm cylinders were flame-sprayed. The buffer coatings were produced using a RotoTec 80 torch and external specific coatings were produced with a CastoDyn DS 8000 torch. Investigations of the coating properties were based on metallography tests, a phase-composition research, a measurement of microhardness, a research of the coating adhesion to the substrate, the abrasive-wear resistance (acc. to ASTM G65 standard), the erosion-wear resistance (acc. to ASTM G76-95 standard) and a thermal-stroke study. The coatings were characterized by a high adhesion to the substrate and also high erosion and abrasive-wear resistance and the resistance to cyclic thermal strokes. Keywords: flame spray, coating, ceramic powder, abrasive-wear resistance, erosion-wear resistance, adhesion strengtĥ lanek predstavlja rezultate {tudija uporabnih lastnosti plamensko nane{enih kerami~nih premazov, izdelanih iz materiala oksidne keramike v obliki prahov na osnovi aluminijevega oksida Al2O3 z dodatkom 3 % titanovega oksida TiO2 in tudi na osnovi cirkonovega oksida (ZrO2) s 30 % kalcijevega oksida (CaO) na podlagi iz nelegiranega konstrukcijskega jekla S235JR.

“…Thermal spraying methods have been notably developed within the last years, due to more and more technologically advanced heat sources and until now new unused coating materials [1][2][3]. Currently, about 70% of the industrial use of this technology consists of manufacturing new machinery parts and equipment demanding a high quality of execution and suitable surface properties.…”

“…The aim of the study was to produce a ceramic coating on the base of Al 2 O 3 with a low content of TiO 2 by cold flame spraying (with minimal pre heating to the range of 40°C) to ensure high hardness and high adhesion. Formation of thin ceramic coatings by flame spraying with such characteristics is relatively difficult to obtain [7][8][9][10][11]. Parameter optimization of spraying and the use of the primer coating such as: Ni-Al-Mo, could minimize the stress level between the substrate material and the coating, at the same time ensuring its high resistance to abrasive wear, erosive wear and also to the cyclic heat stroke.…”

The paper presents the results of the properties of flame sprayed ceramic coatings using oxide ceramic materials coating of a powdered aluminium oxide (Al2O3) matrix with 3% titanium oxide (TiO2) applied to unalloyed S235JR grade structural steel. A primer consisting of a metallic Ni-Al-Mo based powder has been applied to plates with dimensions of 5×200×300 mm and front surfaces of Ø40×50 mm cylinders. Flame spraying of primer coating was made using a RotoTec 80 torch, and an external coating was made with a CastoDyn DS 8000 torch. Evaluation of the coating properties was conducted using metallographic testing, phase composition research, measurement of microhardness, substrate coating adhesion (acc. to EN 582:1996 standard), erosion wear resistance (acc. to ASTM G76-95 standard), and abrasive wear resistance (acc. to ASTM G65 standard) and thermal impact. The testing performed has demonstrated that flame spraying with 97% Al2O3 powder containing 3% TiO2 performed in a range of parameters allows for obtaining high-quality ceramic coatings with thickness up to ca. 500 µm on a steel base. Spray coating possesses a structure consisting mainly of aluminium oxide and a small amount of NiAl10O16 and NiAl32O49 phases. The bonding primer coat sprayed with the Ni-Al-Mo powder to the steel substrate and external coating sprayed with the 97% Al2O3 powder with 3% TiO2 addition demonstrates mechanical bonding characteristics. The coating is characterized by a high adhesion to the base amounting to 6.5 MPa. Average hardness of the external coating is ca. 780 HV. The obtained coatings are characterized by high erosion and abrasive wear resistance and the resistance to effects of cyclic thermal shock.
