Wear behavior of flame-sprayed Al2O3–TiO2 coatings on plain carbon steel substrates

Microstructural, thermal and mechanical properties of HVOF sprayed Ni–Al-based bond coatings on stainless steel substrate

“…The physical bonding is a result of particle adhesion to the substrate by Van Der Waals forces (Celik et al, 2006;METKO, 2001). Cohesive strength depends on the roughness, temperature difference and bond/cohesive strength of the previously coated surface (Shimadzu, 2003;Ak et al, 2004;Kusoglu et al, 2005;Celik et al, 2003;Cetinel et al, 2003;Uyulgan et al, 2003;Scrivani et al, 2001;Liao et al, 2000). The bond strength achieved by the HVOF system is 25% greater than that found using other thermal spraying processes.…”

“…Sample was mounted on a plate that has a reciprocating motion with 1 Hz and 12 mm stroke while pin was fixed. The total sliding distance was 9.6 m. Further details regarding wear tests of coatings were described elsewhere (Celik et al, , 2006METKO, 2001;Kusoglu et al, 2005;Cetinel et al, 2003;Uyulgan et al, 2003;Scrivani et al, 2001). The microstructural analysis of the worn surfaces was examined by SEM.…”

Mechanical properties of atomic layer deposition (ALD) TiO2 layers on stainless steel substrates

“…One of the most commonly used materials of this type is titanium dioxide (TiO 2 ) [8][9][10]. Thin layers based on TiO 2 are characterized by such properties as high transparency, stability (thermal, chemical), corrosion resistance and biocompatibility [11][12][13]. Literature data indicates, however, a number of undefined phenomena accompanying the production of TiO 2 films using the atomic layer deposition method on the surface of metal materials [14][15][16][17][18].…”

Influence of Surface Modification on Properties of Stainless Steel Used for Implants / Wpływ Modyfikacji Powierzchni Na Właściwości Stali Nierdzewnej Stosowanej Na Implanty

“…Thus, ceramic coatings seems to be very attractive for their good resistance to heat, corrosion, and wear (higher than metals) [2][3][4][5]. In recent years TiO 2 has been the focus of extensive research its due to versatile applications in self-cleaning surfaces, sterilization, air-and water-purifications, solar cells, and bio-compatible devices etc [6][7][8]. TiO 2 and its mixture with other oxides such as SiO 2 , Al 2 O 3 have also been used as protective coatings to stainless steel [9][10][11].…”
