Characterization of the tribological properties of bismuth-titanate coatings synthesized by sol-gel on 316L stainless steel substrates
Bautista-Ruiz, Jorge; Aperador Chaparro, Willian; Olaya, Jhon (Tribology in IndustryBelgrado , Serbia, 2019)The objective of this investigation was to obtain ceramic coatings of bismuth titanate by Sol-gel synthesis on 316L stainless steel substrates using bismuth nitrate pentahydrate (III) and titanium tetrabutoxide as precursors. ... -
Effect of nitrogen flow ratio on microstructure, mechanical and tribological properties of TiWSiN x thin film deposited by magnetron co-sputtering
Olaya, Jhon; Macias Ramirez, Hugo Alejandro; Aperador Chaparro, William Arnulfo; Yate, L; L.E, Coy (Applied Surface ScienceBogota , Colombia, 2018-10-31)We investigate the deposition of TiWSiNx thin films by means of the method of reactive magnetron co-sputtering, setting the nitrogen flow ratios N2/(Ar + N2) at 4.8%, 9.1%,16.7 and 33.3%. The crystallographic structure of ... -
Synthesis and corrosion resistance evaluation of coatings of SiO2-TiO2-ZrO2-BiO2 on 316L stainless produced by sol-gel
Olaya, Jhon; Bautista-Ruiz, Jorge; Alfarez, Fabio Leonardo (Boletin de la Sociedad Espanola de Ceramica y VidrioMadrid , España, 2018-10)En este trabajo se presenta la síntesis y la evaluación de la resistencia a la corrosión de recubrimientos de SiO2-TiO2-ZrO2-BiO2 depositados por la técnica de centrifugado sobre acero inoxidable AISI 316L.
