EN Metallic materials such as titanium and titanium alloy generally show good mechanical properties but their biocompatibility is limited. In order to manufacture implants which combine improved mechanical properties of metallic material with biotolerance of ceramics, hydroxyapatite coatings are applie[...]

EN This study presents the test results of Ti-46Al-7Nb-0.7Cr-0.1Si-0.2Ni alloy isothermal oxidation with regard to a coating of SiO2 deposited by the sol-gel method. The oxidation test was carried out in air at 900°C. The SiO2 coating is not an effective and stable diffusive barrier, which would consid[...]

PL Powłoki organiczne są najbardziej powszechnie stosowanym i stosunkowo tanim sposobem ochrony przed korozj metalowych elementów i obiektów inżynierskich. Obecnie nie istnieją wiarygodne i skuteczne metody wyboru i oceny organicznych powłok przeciwkorozyjnych. Można to tłumaczyć skomplikowaniem kinety[...]
EN Organic coatings are the most common and cost effective mode of corrosion protection for metallic objects and engineering structures. Nowadays, there are no reliable and efficient methods for the choice of protective coatings and evaluation of their efficiency. This can be explained by the very comp[...]

EN Properties of Fe-Zn coatings depend mainly on their phase composition. Therefore, steel sheets with Fe-Zn coatings, so called "galvannealed" coatings with various iron content - underalloyed, optimally alloyed and slightly overalloyed Fe-Zn coatings were used to perform formability tests. Phase comp[...]

EN The modern coatings used in arthroplasty for long term implants are reviewed. The phosphate coatings are the most popular technique to improve the bone-implant interfacial strength and promote the osseointegration. The plasma spraying, electrophoretic precipitation, powder metallurgy, ion beam sputt[...]

EN In the present work an influence of heat treatment temperature on the morphology of TiO2 sol-gel coatings is presented. The sol-gel TiO2 coatings were deposited onto Co-Cr-Mo alloy substrate. Scanning electron microscopy examination revealed very good quality of the coatings treated up to 600oC temp[...]

PL Materiały metaliczne, takie jak tytan i jego stopy, posiadają zazwyczaj dobre własności wytrzymałościowe, natomiast ich biotolerancja jest ograniczona. Hydroksyapatyt jest dobrze znanym materiałem bioceramicznym, który ze względu na swoje zalety (bioaktywnośé) znajduje szerokie zastosowanie w medycy[...]
EN Metallic materials such as titanium and titanium alloy generally show good mechanical properties but their biocompatibility is limited. Hydroxyapatite is a well-know bioceramics that is extensively used in medicine. Due to its reasonable mechanical behaviour under low-load conditions and excellent b[...]
