“…Similar results was noticed elsewhere [13]. The reduce of the anodic current of the coated substrates was owing to that Ti and Zr ions will react with nitrogen and deposited onto AISI304 substrate by PMS technique cause high dense with compact grain distribution, this dense in coat protects the corrosive ions penetration through surfaces in coated layers [30]. -4 mm/year to 0.526x10 -4 mm/year for the sample that was coated for applied power of 175 W. This can be revered to the raise of the relative intensity of hard (Ti, Zr) N (111) plane with increasing the applied power up to 175 W as in Fig.…”

Abstract-The effectivness of applied power on structure and tribomechanical properties of Ti-Zr-N films, deposited on AISI304 stainless steel substrate, by pulsed magnetron sputtering PMS technique was investigated. The composition and Ti-Zr-N films properties were varied as the applied power changing from 125 W up to 225 W at a fixed deposition time of 90 min and constant nitrogen / argon gas ratio of 20%. XRD analysis reveals that, formation of FCC structure Ti-Zr-N as a solid solution phase and TiN as a chemical compound phase. The dominant phase Ti-Zr-N shows a preferred orientation in (111) orientation. It was obtained that all Ti-Zr-N coatings have a nanostructured appearance. The microhardness of the thin films is increased up to 1000 HV0.025 which approximately represents 4-folds as that of AISI304 stainless steel substrate. Furthermore, the rate of wear has been improved from 66.64 mm 3 /Nm for AISI 304 substrate to 15.75 mm 3 /Nm after depositing TiZr-N. Over and above, the coefficient of friction (C.O.F) is decreased from nearly 0.69 for the austenitic substrate to nearly 0.16 after coating. Finally, the corrosion performance of Ti-Zr-N films is improved about 1000 times as that of AISI304 substrate.

“…It showed that compared to ZrO 2 coatings, Ag–ZrO 2 composite coatings had better results against Escherichia coli and Staphylococcus aureus strains . Another study with the reactive magnetron co‐sputtering technique on implants demonstrated less bacterial attachment, hemocompatibility, and anticorrosion activities of TiZrN coating on 316L SS against S. aureus and E. coli . Furthermore, the 316L SS substrate was modified with TiN, TiO 2 single‐layer and TiN/TiO 2 multilayer coatings by the magnetron sputtering technique.…”

The growth of technology and requirements globally for various commodities has brought about new challenges. Biofilms are aggregations of microbial cells, which contaminate and spoil industrial components and environments. These microbial cells with extracellular polymeric substances colonize living and nonliving surfaces and pose a serious problem for all industries, affecting their processes, leading to a reduction of product quality and economic loss. Industries, such as medical, food, water, dairy, wine, marine, power plants are exposed to biofilm formation. Pipe blockages, waterlogging and reduction of the heat‐transfer efficiency, hamper the operating system of plants. Many industries do not set up remedial measures to control biofilm formation as they are not aware of this threat. Various conventional methods to control these biofilms are adopted by industries in their regular workflow, but these are temporary solutions. This calls for further research into remediation of the biofilm and its control for industrial components. This review article addresses the problems of biofilms and proposes solutions for various industrial components. Nanotechnology promises several options, and bring about a new aspect into the industrial economy, by solving the problems of environmental biofilms.

“…Se puede observar que los picos de los patrones DRX de los recubrimientos producidos se localizan entre los picos del ZrN y TiN, con valores 2θ de 34,76°, 40,15° y 73,13°, correspondiendo con los planos (111), (200) y (222) de la fase (Ti,Zr)N con estructura cristalina FCC. Estos valores concuerdan con la tarjeta JCPDS 89-5214 y trabajos previos donde estudian recubrimientos de TiZrN (Kaliaraj, et al, 2015;Chinsakolthanakorn, et al, 2012) y TiZrSiN Saladukhin, et al, 2015b), ambos depositados por co-sputtering reactivo.…”

Películas delgadas de ZrTiSiNiN fueron depositadas sobre sustratos de vidrio y silicio mediante co-sputtering reactivo con magnetrón usando blancos de Ti5Si2, Zr. En esta investigación se varío el contenido de Ni en los recubrimientos mediante la adición de cubos de Ni ubicados sobre el blanco de Zr. La morfología superficial, la estructura cristalina y el espesor de las películas fueron evaluadas mediante microscopía electrónica de barrido (SEM), difracción de rayos X (XRD) e interferometría respectivamente. La resistividad eléctrica se midió mediante el método de cuatro puntas y sus propiedades ópticas se caracterizaron por espectroscopía ultravioleta / visible (UV/Vis). Con base en los resultados de XRD se observó que el Níquel actúa como refinador de grano al lograr disminuir el tamaño de cristalito de 27 nm hasta 15 nm cuando la concentración de Níquel aumenta de 0 at% a 6,8 at%. Tanto la resistividad eléctrica y el “band gap” óptico de los recubrimientos aumentaron con la disminución del tamaño del cristalito como resultado del aumento de la densidad de límites de grano y del efecto de confinamiento cuántico.
