Effect of plasma sprayed and laser re-melted Al2O3 coatings on hardness and wear properties of stainless steel

Micromorphology analysis of sputtered indium tin oxide fabricated with variable ambient combinations

“…Our previous studies demonstrated that the corner frequency is found similar to average decay length, and hence to average grain diameter [28,29]. As a quick characterization tool, fractal analysis proved to be useful in studies of morphology and mechanical properties of various surface structures upon heat treatment [30][31][32], nanomechanical processing [33,34], in contact with body tissues and fluids [35][36][37][38]. Obtained results established a bridge between specific geometry of residual surface and its tribological and physical characteristics [39][40][41].…”

Anticorrosion assessment of Al2O3‐TiO2 composite thin films derived from sol‐gel dipping technique

“…As mentioned in previous studies, TiO 2 thin film could diminish corrosion current density and make the steel substrate passive . On the other hand, Al 2 O 3 as a ceramic material with high hardness has been identified as causing the increase in corrosion resistance and improving surface hardness when it is applied on steel . By simultaneous application of these two ceramic materials over steel, we can take advantage of corrosion and abrasion behaviors.…”

“…[5][6][7][8][9]15,16 On the other hand, Al 2 O 3 as a ceramic material with high hardness has been identified as causing the increase in corrosion resistance and improving surface hardness when it is applied on steel. 17 By simultaneous application of these two ceramic materials over steel, we can take advantage of corrosion and abrasion behaviors. So far, some efforts have been made for synthesizing Al 2 O 3 -TiO 2 combination in the form of powder and thin film.…”

Surface remelting treatment of 7075 aluminum alloy—microstructural and technological aspects

“…One of the modern methods of modifying the surface layers of engineering materials is surface heat treatment carried out using concentrated heat sources such as a laser beam or plasma jet. For instance magnesium alloys [7,8], plasma sprayed coatings [9,10], aluminum alloys [11][12][13] and other engineering materials are subjected to treatment by means of concentrated heat sources. Aluminum alloys are materials with a very wide application resulting from their low density and good strength properties.…”
